Authors: Zhang Qingwen , Chen Zhongbin , Li Jizhou , Cai Qingnian , Zhang Qin , Zhang Fuling
Published: April 2008

Abstract Total mRNA from venom glands of newly emerged queen bees was reversely transcribed into cDNA and cloned into the EcoRI site of plasmid λgt11; cDNA library for bee venom was thus constructed. PCR technique was used to produce the melittin coding sequence from the cDNA library. A 87 bp product was produced and inserted into the EcoRI and PstI sites of the high level expression vector pBV220. Recombinant plasmid pBM95 was transformed into the competent cells of E.coli JM101. After screening transformants on LB medium with ampicilin, structure of the recombinant plasmid pBM95 from transformants was analyzed and melittin gene in pBM95 was sequenced. The cloned cDNA coding for honey bee melittin was obtained.

Authors: Wu Deming , Yan Yunhua , Cui Junrong
Published: April 2008

Abstract Gas chromatographic and mass spectral analyses were conducted on the pheromone gland extracts of female moth of Helicoverpa armigera (Lepidoptera:Noctuidae). Saturated aldehyde (16:Ald), (Z)‐9‐hexadecenal (Z‐9–16:Ald), (Z)‐11‐hexadecenal (Z‐11–16:Ald), hexade‐canol (16:OH) and (Z)‐11‐hexadecenol (2–11–16:OH) were found from gland extracts in the ratio of 6.1:4.5:100:3.5:8.8. In field tests of Shandong and Shanxi Provinces, 2 mg blends of Z ‐11–16:Ald and Z‐9–16:Ald (97:3) applied on a rubber dispenser effectively attracted H. armigera males. The addition of 4%‐7%16:Ald to the binary mixture caused increase over that of the binary mixture. The addition of 1%Z‐11–16:OH to binary or trinary mixture may reduce catches, while addition of 5% Z‐11–16:OH reduced catches singnificantly.

SYSTEMIC INSECTICIDAL ACTION OF AZADIRACHTIN, NEEM SEED AND CHINABERRY SEED EXTRACTS APPLIED AS SOIL DRENCHES TO POTTED PLANTS
Authors: Hu Meiying , Klocke James A. , Barnby Mark A. , Chiu Shinfoon
Published: April 2008

Abstract  The systemic insecticidal activities of: 1) azadirachtin, a potent insect antifeedant and growth regulator isolated from seeds of the neem tree, Azadirachta indica, 2) a neem seed extract containing 0. 30 quantitative fraction of azadirachtin, and 3) a methanolic extract of seeds from the chinaberry tree, Melia azedarach, a close relative of neem were determined. Soil drenches of azadirachtin or the neem seed extract at 1 and 2. 5 mg to potted potato (Solanum tuberosum) and tomato (Lycopersicon esculentum), remarkably retarded the growth of Manduca sexta larvae and strongly disrupted the pupation of Leptinotarsa decemlineata larvae, respectively. However, five to ten times as much azadirachtin or neem seed extract was needed to reduce the amount of tomato and potato foliage consumed. On sorghum (Surghum biocolor), much higher quantity (≥25 mg) of azadirachtin or the neem seed extract was necessary to slow the population growth of Schizaphis graminum, and prolong the survival of treated plants. But methanolic extracts of chinaberry seeds (M. azedarach) from two sources (Guangdong, PRC and Hurricane, Utah, USA) at 150 mg per pot were ineffective in reducing aphid population growth and preventing plant damage.

SINGLE‐HELICOVERPA ARMIGERA TEST TO DETERMINE INSECTICIDE RESISTANCE GENOTYPE FREQUENCY*
Authors: Qiao Chuanling , Yan Yanchun
Published: April 2008

Abstract  A sensitive technique for identifying insecticide resistance genotype frequency of the Ace gene existing in natural populations of Helicoverpa armigera in China is described. The technique is based on the comparison of acetylcholinesterase (AChE) activity in 3 equal aliquots, which are taken from the homogenate of a single H. urnzigera: 1) in absence of inhibitor (well No. 1); 2) in absence of enzyme precursor (well No. 2); and 3) in presence of a concentration of propoxur inhibiting the AChE coded by the AceSallele but not by the AceRallele (well No. 3). An intensity of same strength in wells No. 1 and No. 3 indicates that propoxur has no effect on AChE activity, and the genotype should be AceRR(when well No. 3 = well No. 1). A same weak intensity in well No. 2 and No. 3 (and a strong intensity in well No. l), indicates that propoxur completely inhibited AChE activity; and the genotype should be AceSs(when well No. 3 = well No. 2). Well No. 3 displaying an intermediate intensity between well No. 1 (strong intensity) and well No. 2 (weak intensity) indicates that AChE activity was partially inhibited by the propoxur concentration and genotype should be AceRs(when well No. 2<well No. 3<well No. 1). The genotype frequency was determined in 1995 and 1996. the AceSSis 76. 1%, 70. 6% for low resistance populations respectively whereas the AceRRis 68. 3%, 65. 3% for high resistance population respectively.
MORPHOLOGICAL STUDIES ON MYZUS PERSICAE IN CHINA
Authors: Yang Xiaowen , Zhang Xiaoxi , Zhang Sufang
Published: April 2008

Abstract  Experiments were carried out to study the morphological characters of Myzus persicae (Sulzer) on tobacco, rape and peach from different localities of China. The results showed that the number of accessory hairs on ultimate rostral segment had no difference among all samples in 14 morphological characters used by Blackman in this study. Cluster analysis indicated that the morphological differences between samples from peach and samples from other host plants was the biggest, the next was the samples from Changchun on tobacco. Compared with peach, the aphid from rape was more similar to that from tobacco in morphology. For the samples on tobacco from the central and southern China, they can be clustered into yellowish‐green group and reddish‐brown group. It shows unlikely to separate successfully the aphids on tobacco from those on non‐tobacco host plants only by morphological characters.
THE RELATIONSHIP BETWEEN INSECT GROWTH REGULATORS WITH JUVENILE HORMONE ACTIVITY AND INSECT FEEDING BEHAVIOURAL RESPONSE
Authors: Jiang Zhisheng , Shang Zhizhen , Zhao Shanhuan , Chiu Shinfoon
Published: April 2008

Abstract  Five insect growth regulators (IGRs) with juvenile hormone (JH) activity including fenoxy‐carb, methoprene, NC‐170, NC‐184 and NC‐196 were selected to study on the relationship between IGRs and feeding behaviour of the fourth instar larvae of Calospilos suspecta (Warren) and the fifth instar larvae of Ostrinia furnacalis Guenee, by topical and dietary applications as well as “diet column” methods. The results indicated that the antifeeding indices of methoprene, fenoxycarb, NC‐170, NC‐184, NC‐196 and toosendanin against the fifth instar larvae of Ostrinia furnacalis in no‐choice test were ‐37. 7, 14. 6, ‐12. 3, 10. 9, 14. 7 and 62. 2% respectively. Methoprene could stimulate the two species of insects to feed, whereas fenoxycarb had some antifeeding activity, and the effects of all the tested chemicals were different. Therefore, disturbances of IGRs with JH activity on insect feeding behavioural response may be one of the mechanisms of action not to be ignored. Moreover, by comparing “diet column” method with “faeces weight” method, it was suggested that the two methods might be applied in bioassay of antifeeding behaviour.
CYTOCHROME P450 MONOOXYGENASES ASSOCIATED WITH PYRETHROID RESISTANCE IN HELICOVERPA ARMIGERA (HÜBNER)
Authors: Dong Yuxin , Zhuang Peijun , Tang Zhenhua
Published: April 2008

Abstract  The relationship between the cytochrome P‐450 (cytP450 monooxygenase and insecticide resistance mechanisms in Helicoverpa armigera was studied. The level of cytP450 and activity of p ‐ni‐troanisole (p ‐NA) O‐demethylase in resistant strain were 1. 71 times and 2. 21 times respectively higher as compared with those of the susceptible strain. Aldrin epoxidase activity showed 1. 35 fold strain difference. Therefore aldrin epoxidase might not be important for H. armigera resistance mechanism, the level of cytP450 and activity of p ‐NA O‐demethylase might play a vital role in H. armigera resistance mechanisms. The reason of different resistance mechanisms among different H. armigera resistant strains is discussed.
STUDIES ON THE PHYLOGENY AND HOST PLANT ASSOCIATION OF LACHNIDAE (HOMOPTERA: APHIDINEA)*
Authors: Zhang Guangxue , Chen Xiaolin
Published: April 2008

Abstract With reference to the material related to the evolution of host‐plant associations, phylogenetic analyses of aphids in Lachnidae are carried out by using 20 taxa and 26 characters. The monophyly of Traminae and Cinarinae are recognized. However, Lachninae is proved to be a polyphyletic group. Three traditional subfamilies, Cinarinae, Lachninae and Traminae are still retained. Three tribes within Cinarinae which include Cinarini, Eulachnini and Schizolachnini are suggested. It is concluded that the ancestral host plants of Lachnidae were deciduous plants rather than coniferous trees or other plants.

ECDYSTEROIDS IN THE LARVA OF HAEMAPHYSALIS LONGICORNIS NEUMANN (ACARI: IXODIDAE)*
Authors: Liu Jingze , Zhao Xiuying
Published: April 2008

Abstract The ecdysteroids (ECs) concentration and their components in the larvae of Haemaphysalis longicornis were determined by radioimmunoassay (RIA) and high performance liquid chromatography (HPLC). ECs ware found in feeding and engorged larvae and absent in unfed larvae. During feeding and the first 3 days after engorgement, ECs were in low level (less than 14. 35pg EE /larva). On the 5th day, they began to increase sharply (29. 87pg EE /larva) and reached their peak (56. 04pg EE /larva) on the 7th day. Then they declined to low value again (19. 38pg EE /larva). HPLC analysis revealed that the ECs components of the RIA peak could be 20‐hydroxyecdysone (20E) and ecdysone (E) on the ratio of 20E: E = 3. 07: 1, which meant 20E was probably the main effective hormone.
SOME BIOCHEMICAL ASPECTS OF RESISTANCE TO CONTROLLED ATMOSPHERE IN LIPOSCELIS BOSTRYCHOPHILA BADONNEL (POSCOPTERA: LIPOSCELIDIDAE)*
Authors: Wang Jinjun , Zhao Zhimo , Li Lungshu
Published: April 2008

Abstract  Adults of the psocid Liposcelis bostrychophila were exposed to an atmosphere containing 35% CO2 and 1% O2 for 30 successive generations at 28 C and 70%–80% RH in order to select a resistant strain to controlled atmosphere (CA). At the 30th generation the resistance factor (LT50 for selected generation / LT50 for non‐selected generation) reached to 5. 6‐folds. The results of biochemical assays showed that the activities of carboxylesterase (CarE) and superoxide dismutase (SOD) in vitro increased considerably from generation to generation during the selection process, and they were closely correlated with the resistance levels. At the 30th generation, the CarE and SOD activities in the resistant strain to CA (CA‐R) were 4. 06‐and 5. 22‐folds as much as those in the susceptible strain to CA (CA‐S), respectively. Exposure to CA resulted in decrease in CarE activity; however, the decreasing range for CA‐S was significantly greater than that for CA‐R. CA had induction effect on SOD within short time, but for CA‐R the induction time was longer and activity induced was higher than CA‐S. Catalase (CAT) activity was also raised with the resistance development, but no statistical relationship was found between CAT activity and CA resistance. No significant difference of both acid phosphatase (ACP) and alkaline phosphatase (ALP) was found in CA‐R and CA‐S during the selection process. Peroxidase (POD) activity was not detected in L. bostrychophila. These suggest that the major mechanism responsible for CA resistance appears to be the enhanced CarE and SOD activities, and probably CAT plays an additionary role to adopt low O2 concentration in CA resistance.
BACILLUS THURINGIENSIS SPECIFIC TO SCARABAEID BEETLES: A REVIEW
Authors: Hori Hidetaka , Kumaraswami N. Selvamuthu , Hayakawa Tohru , Mitsui Toshiaki
Published: April 2008

Abstract  Since the first report of Bacillus sotto by Ishiwata in 1901, thousands of related papers about Bacillus thuringiensis have been documented. In the field of biocontrol of insect pests by this bacterium, after the initial discovery of several B. thuringiensis isolates specific for lepidopteran insects, the isolation of B. thuringiensis israelensis, specific to dipteran larvae by Goldberg and Margalit, and B. thuringiensis tenebrionis, specific to some group of coleopteran insects by Krieg et al. were epoch making advances. In 1992, Ohba et al. isolated B. thuringiensis ja ponensis strain Buibui, which was specific to only scarabaeid larvae. This isolate is the main target of our discussion in this review. These discoveries by which not only B. thuringiensis sciences, but also applied biological control strategies have been enriched, which inspirit us to screen novel isolates.

On the other hand, the fields of molecular biology and biochemistry studies on the structural elucidation of toxin proteins and mechanism of action have also tremendously progressed. But the complete mechanism has yet to be solved. For instance, interaction between receptor proteins locating on the plasma membrane of insect midgut epithelial cells and insecticidal proteins has not been fully sketched‐ In a way, this field is still in chaos. Addressing these exciting and enigmatic subjects will eventually lead to the construction of sustainable agriculture in the 21st century.

Published: April 2008

Abstract  Differences in sequences of ribosomal DNA second internal transcribed spacer (ITS) among Anopheles sinensis, An. lesteri and An. yatsushiroensis from Korea were compared. The PCR amplified rDNA‐ITS2 fragments were sequenced directly. Three samples of each species were individually determined.

Lengths of the ITS2 regions were 468bp in An sinensis, 451bp in An lesteri and 453bp in An yatsushiroenesis and GC contents were 44.87 % 46.2 % and 45.7 % respectively. Variations of the sequences ranged from 12.16 % to 30.7 % among the three species. The differences of the rDNA‐ITS2 sequences would be useful for molecular identification of the three members of Anopheles hycanus complex from Korea.

Authors: Peng GONG , Xiao‐xi ZHANG , Xiao‐wen YANG , Xiao‐fen CHEN
Published: April 2008

Abstract  The RAPDPCR technique was used to determine the DNA polymorphism of the aphid Aphis gossypii(Glover) collected from different host plants and in different seasons. Three primers were selected from 20 primers and used for cluster analysis based on the data of Nei's genetic distance (D). The results showed that the aphids on Chinese prickly ash differentiated obviously from the aphids on the other four host plants at DNA level. The seasonal population of cotton aphid might be clustered into three groups, i.e. the spring and autumn yellow colored aphids, the spring and autumn green colored aphids and the yellow dwarf form aphid in summer.

However, the genetic relationship of dwarf form was more closely to the spring and autumn green colored aphid.

EFFECTS OF SUBLETHAL ESERINE ON THE CHEMICAL COMMUNICATION SYSTEM OF ASIAN CORN BORER, OSTRINIA FURNACALIS (GUENEE)*
Authors: Zhi‐hua YANG , Jia‐wei DU , Hong‐chun ZHOU , Shao‐fu XU
Published: April 2008

Abstract Topically applied sublethal doses of eserine may interrupt chemical communication between the two sexes of Asian corn borer, Ostrinia furnacalis (Guenee), by affecting calling and sex pheromone titre released by the females. (1) Studies on the effects of sublethal eserine on the chemical communication system of O. furnacalis indicated that there was a decreasing probability of females calling and sex pheromone titre as the eserine dosage increased from 0.27 to 2 700 ng, with no effect on the periodicity. However, at 2 700 ng, the E/Z ratio of the sex pheromone components was affected. The sexual chemical communication system could not control within narrow level. (2) The recovery test of 27ng‐treated female indicated that the calling percentages of the 1st, 2nd and 4th day post‐treatment were 50%, 78% and 84% respectively. Sex pheromone titre was 40%, 40% and 80% of control female repectively. There was a trend toward recovery. The sexual chemical communication system could control within narrow level from the 2nd day post‐treatment.
ESTERASE PHENOTYPES IN NATURAL POPULATIONS OF CULEX PIPIENS PALLENS (DIPTERA: CULICIDAE) AND THEIR VARIATIONS UNDER INSECTICIDE SELECTION*
Authors: Jin‐fu WANG
Published: April 2008

Abstract Three populations of Culex pipiens pallens Coquillett, from Hangzhou, Linhai and Jinhua, were determined for their probability of resistant esterase phenotypes. Further, each population was selected with dipterex, chlorpyrifos, temephos and malathion at a given dose of 60%‐70% mortality and was determined for the variation of resistant esterase phenotypes in its offspring. The results indicated that esterase B1 phenotype was dominant in three populations although different natural populations have a different probability distribution of esterase B phenotypes. Insecticide selection showed that various esterase loci seemed to have different selective advantages under different insecticide pressures. The esterase B1 phenotype was selected under temephos, and the esterase B2 phenotype was selected under dipterex and chlorpyrifos. Except for the esterase B1 phenotype, the heterozygote of B1/B2 phenotypes was detected under malathion pressure. These results are discussed in relation to the selective advantages of esterase genes to OP pressure and mosquito control strategies.

STUDIES ON THE KINETICS OF ACETYLCHOLINESTERASE IN THE RESISIANT AND SUSCEPTIBLE STRAINS OF HOUSEFLY (MUSCA DOMESTICA)
Authors: Ming‐an SHI , Jian‐zhong YUAN , Jun WU , Pei‐jun ZHUANG , Zhen‐hua TANG
Published: April 2008

Abstract Acetylcholinesterase (AChE) in the susceptible (S) and the resistant (R) strains of housefly (Musca domestica) was investigated using kinetic analysis. The Vmax values of AChE for hydrolyzing acetylthiocholine (ATCh) and butyrylthiocholine (BTCh) were 4578.50 and 1716.08nmol/min/mg* protein in the R strain, and were 1884.75 and 864.72 nmol/min/mg. protein in the Sstrain, respectively. The Vmax ratios of R to S enzyme were 2.43 for ATCh and 1.98 for BTCh. The Km values of AChE for ATCh and BTCh were 0.069 and 0.034 mmol/L in the S strain, and 0.156, 0.059 mmol/L in the R strain, respectively. The Km ratios of R to S enzyme were 2.26 for ATCh and 1.74 for BTCh. The ki ratios of S to R enzyme for three insecticides propoxur, methomyl and paraoxon were 46.04, 4.17 and 2. 86, respectively. In addition, kcat and kcat/Km for measuring turnover and catalytic efficiency of AChE were determined using eserine as titrant. The kcat values of AChE from the R strain for both ATCh and BTCh were higher than those values from the S strain. But the values of kcat/Km were in contrary to the kcat values with R enzyme compared to S enzyme. The AChE catalytic properties and sensitivity to the inhibition by three insecticides in the R and S strains of housefly were discussed based on contribution of Vmax, Km, ki, kcat and kcat/Km. All these data implied that AChE from the R strain might be qualitatively altered. We also observed an intriguing phenomenon that inhibitors could enhance the activity of AChE from the resistant strain. This “flight reaction” of the powerful enzyme might be correlated with the developing resistance of housefly to organophosphate or carbamate insecticides.

Abstract The resistance mechanism underlying phoxim resistance was investigated through biochemical assays. The results show that there are marked relations between the phosphatase activity and resistance to phoxim. Furthermore, there is a significant difference in the Ki values of AChE between the two strains and it is inferred that the change in ability of binding to phoxim is a mechanism responsible for resistance to phoxim. The metabolic inhibitors Triphenyl Phosphate (TPP) and O,O‐diethyl‐O‐phenyl‐thiophosphate (SV1) displayed significant synergism of phoxim toxicity to the two strains. It implied that esterase might be involved in resistance. However, there is no marked correlation between resistance and CarE.

Published: April 2008

Abstract The preference and density response test9 of egg parasitoid, Ooencyrtus nezarae Ishii, to the eggs of soybean stick bugs, Riptortus clavatus Thunberg and Piezodorus hybneri Gmelin, were carried out in this study. In the free choice test, O. nezarae emerged from both eggs of stick bug prefer R. clavatus eggs only in the various ratios of host egg densities. In non‐choice test, O. nezarae emerged from P. hybneri eggs parasitize both R. clavatus and P. hybneri eggs, showing a high parasitism on host eggs. However, O. nezarae reared on R. clavatus eggs had a significantly lower parasitism on the eggs of P. hybneri. Olfactometer test showed that the odor emitted from R. clavatus eggs had a great influence on the host searching and parasitizing behavior of O. nezarae. The number of R. clavatus and P. hybneri eggs parasitized by O. nezarae gradually increased with the increase of host egg densities. However, the parasitism of O. nezarae to R. clavatus eggs decreased with the increase of host density. The parasitism of O. nezarae are significantly lower (P < 0.05) on host egg P. hybneri under the laboratory condition, especially for O. nezarae emerged from R. clavatus eggs. This research results implied that in the soybean field, there were some optimal or spatial barriers for O. nezarae to find R. clavatus eggs efficiently.

Authors: Jun‐xiang WU , Feng YUAN , Ya‐mei ZHANG
Published: April 2008

Abstract The changes of fatty acids in larvae of the wheat blossom midge, Sitodiplosis mosellana (Gehin) at different periods were examined by gas choromatography. There were 10–16 kinds of fatty acids, of which the predominant ingredients were palmitic (C16:0), oleic (C18:1) and linoleic (C18:2) acids which were more than 95% in total fatty acids, stearic acid (C18:0) about 2%‐3.5% and any of the others was less than 1%. The fatty acid compositions increased from mid‐May, when larvae of the wheat blossom midge left the wheat‐ears and fallen on the ground, to April of next year before pupating and emerging. No arachidic acid (C20.0) was discovered in over‐summering, over‐wintering as well as inactive over‐wintered larvae. The content of saturated fatty acids in over‐summering, overwintering as well as inactive over‐wintered larvae were less than those of in active over‐wintered larvae and wheat‐ear larvae. Therefore, changes of the arachidic acid and the proportions of saturated fatty acids/unsaturated fatty acids could be used as one of the biochemical criteria to determine the active state and the degree of diapause in larvae of the wheat blossom midge.

Published: April 2008

Abstract A 6.12 kb Xbal‐H fragment of the Helicoverpa armigem single nucleopolyhedrovirus (HaSNPV) gemone was cloned and the complete sequence of this fragment was sequenced by random sequencing method. Sequence comparison and analysis revealed an ORF13 which was homologous to ie‐1 of Auiographa California nucleopolyhedrovirus (AcMNPV). The homologous encoding gene is ie‐1. The total length of the encoding region of HaSNPV gene was 1986 bp and was predicted to encode 661 amino acid protein(IE‐1) with molecular weight of 76.5 kD. The alingment of putative HaSNPV IE‐1 amino acid sequence with those of other 9 reported baculoviruses IE‐Is showed that the HaSNPV IE‐1 was most closely related to Helicoverpa zea nucleopolyhedrovirus (HzNPV) IE‐1, with 97% amino acid identidy. But it showed a low degree of sequence similarity to those of AcMNPV, Bombyx mori nucleopolyhedrovirus (BmNPV), Choristoneura fumiferana nucleopolyhedrovirus (CfMNPV), Lymantria dispar nucleopolyhedrovirus (LdMNPV), Orgyia pseudotsugata nucleopolyhedrovirus (OpMNPV), Spodoptera exigua nucleopolyhedrovirus (SeMNPV), Plutella xylostella granulovirus(PxGV) and Xestia c‐nigrum granulovirus (XcGV), with 23%, 23%, 23%, 25%, 23%, 14%, 27% and 7% amino acid identity, respectively. A phylogenetic tree of ten baculoviruses IE‐1 was also given.

Authors: Jun CAI , Gong‐yin YE , Cui HU
Published: April 2008

Abstract Studies on the effect of parasitization by the endoparasitoid on host humoral immune reactions are carried out with the pupal endoparisitic wasp, Pteromalus puparum, and its host, Pieris rapae. Phenoloxidase (PO) activity of parasitized hosts hemolymph increased significantly at 12 h, day four and day five after parasitization. Hem‐agglutination activity of parasitized hosts hemolymph was always higher than that of wounded and unparasitized ones. Moreover, antibacterial activity of parasitized hosts hemolymph became more and more stronger, whilst wounded and unparasitized pupae only owned a weak antibacterial activity. It suggested that activities of humoral immune factors of Pieris rapae could be influenced to some degrees by P. puparum.

Abstract After ammonium sulphate precipitation, Sephadex G‐75 gel filtration, Lys‐Sepharose 4B affinity chromatography and elution from electrophoresis, the fibrinolytic protease (TAFP) was isolated and purified from the extract of T. amaenus Walker gut. It appeared a single band corresponding to molecular weight of approximately 67kD on SDS‐PAGE and an probably pI of 7.2 on IEF. On fibrin plate and plasminogen‐free fibrin plate (heated at 85°C for 30 minutes to eliminate plasminogen), TAFP showed same fibrinolytic activity. The result might indicate that TAFP is a fibrinolytic enzyme degrading fibrin, as well as a plasminogen activator degrading fibrin via activating plasminogen. The result of chromogenic substrates indicated that TAFP possesses trypsin‐like activity specifically degrading argininyl amide bond or peptide bond, but has no chymotrypsin activity. TAFP was almost inhibited powerfully by antipain, PMSF, soybean trypsin inhibitor and soybean Bowman‐Birk inhibitor. However, leupeptin, antitrypsin and TLCK was more powerful effective inhibitors of TAFP. Optimal reaction pH of TAFP was 7.5, and it was stable in 5.5–7.0 of pH range.

Abstract To obtain new ideas on optimal composite material structure, the fine structures of the trabeculae of the elytra of Allomyrina dichotoma (Iinné) and Prosopocoilus inclinatus (Motschulsky) were investigated using scanning electron microscope. The shape and size of trabeculae, which form the internal bridges between the upper and lower surfaces of the elytra, depend on the species of beetles. Complex surface structures (stripes or bandings) were found in those of A. dichotoma, but less in P. inclinatus. The trabeculae consisted of three parts: the surface part, the cylindrical layer and the central part. The surface and the central part were mainly protein substances which could be dissolved by KOH. The cylindrical layer had many chitin fibers with different orientation, and they were embedded in a protein matrix, and were connected to endocuticle chitin fibers on the upper and lower parts of the lamination.

Abstract The population of the citrus red mite, Panonychus citri (McGregor), does not increase on pear from spring to mid‐summer but thereafter increases abruptly. To elucidate this phenomenon, we compared the performance of the mites on pear leaves with that on citrus leaves, at different time throughout the pear‐growing season. No significant difference was detected between the oviposition rate on pear and that on citrus throughout the season. However, the survival rate of ovipositing females that had fed on pear and the hatch rate of eggs laid by those females were significantly lower than those for females that had fed on citrus, until August. However, no significant difference was observed thereafter. The results showed that the decline of the population of citrus red mite before autumn is due to the high mortality of adult females that had fed on pear leaves and the low hatch rate of the eggs produced by those females.

Published: April 2008

Abstract Ten populations of the whitefly Bemisia tabaci (Gennadius) collected from eight fieed and ornamental crops from seven provinces/cities in China were determined using RAPD‐PCR. Results showed that the 10 populations of B. tabaci could be classified into three distinct groups: a Biotype B group, a Guangxi group, and a Fujian group. The whiteflies in the Biotype B group were collected from sweetpotato and cotton in Beijing, tomato in Shandong, poinsettia in Shanghai and Guangdong, cabbage in Fujian, and hemp and eggplant in Xinjiang. The Guangxi group were collected from pumpkin in Naming, Guangxi, and the Fujian group, from sweetpotato in Fujian. It was notable that B. tabaci specimens collected on cabbage in Fujian belonged to the Biotype B group. It is clear that Biotype B does now occur in China, in Reijing, Shandong, Xinjiang, Shanghai, Fujian and Guangdong. It is likely that the Guangxi and Fujian groups are native to China.

Abstract The bionomics of Campoletis chlorideae and the regularity of its seasonal fluctuations were studied in Changsha district, Hunan province. Field investigation indicated that there were ten generations of C. chlorideae a year, of which seven occurred in cotton fields. Three peaks of cotton bollworm parasitization by C. chlorideae were observed, early May to late June, mid August to early September, mid September to mid October respectively. One peak occurred in tomato and tobacco fields, the other two in cotton fields. The parasitization rate ranged from 25. 1 % ‐63. 1 %. The total development time from egg to adult ranged from 13. O days at 32°C to 75. 5 days at 11. 6 °C. Each wasp could parasitize the 5–23 second instar larvae of tobacco caterpillar. C. chlorideae could parasitize the cotton bollworm, beet armyworm and tobacco caterpillar, but preferred the cotton bollworm larvae. C. chlorideae could parasitized 1st‐ 3rd instar larvae of the tobacco caterpillar, but seldom parasitzed 4th ‐ 6th instar larvae. Moreover, C. chlorideae preferred second instar larvae. Theoretical models for developmental speed, adult longevity and the influence of temperature were proposed. The overwintering of C. chlorideae Uchida was also discussed. Moreover, methods for utilization of C. chlorideae Uchida in crop protection were presented and the bionomics of Curyoletis chlorideae in both the Yangtze River Valley and Yellow River Valley were compared.

Published: April 2008

Abstract Coccophagus scutellaris (Dalman) is one of the specific parasitoids that attack soft scale insects in Egypt. In the present study, C. scutellaris was reared from 6 species of soft scale insects. These are Ceroplastes flori‐densis Comstock, Coccus hesperidum L., Pulvinaria floccgera (Westwood), P. psidii Maskell, Saissetia coffeae (Walker) and S. oleae (Oliver). The abundance of C. scutellaris was monitored from July to Nov. 1999–2000 in five localities in Egypt, the Beni‐Suef, Cairo, Giza, Gharbiya and the Northern coast. C. scutellaris is considered an effective parasitoid of S. coffeae and S. oleae with maximum parasitism rates reaching 26% and 22% in Nov. and Aug. 1999, respectively.

Published: April 2008

Abstract Acetamiprid is a novel neonicotinoid insecticide invented by Nippon Soda Co., Ltd. To explore the possibility of acetamiprid as larvicide of mosquitoes, lethal and sublethal effects of acetamiprid on the larvae of Culex pipiens pallens were studied by immersion method in the laboratory. The results indicated that the larvae of Culex pipiens pallens were sensitive to acetamiprid. The mortality of larvae peaked at 72 h after treatment. The 1 st instar larvae was the most susceptible to acetamiprid, and the 4th instar larvae was the most tolerant to acetamiprid, the LC, values were 0. 020 mg/L and 0. 296 mg/L at 72 h after treatment, respectively. Sublethal concentrations of acetamiprid could delay the development of larvae and decrease the weight of pupa. We suggested that acetarniprid is a safe and effective substitute for the using larvicides of mosquitoes.
