Evaluation of a Synthetic Juvenile Hormone Against Two Species of Fly Larvae (Dipt.)1
Authors: Mahadeo C. Raymond , Salman Wasti S. 
Published: July 2010

AbstractLarvae of the house fly, Musca domestica L. and the blow fly, Phormia regina (Meig.) were treated with a juvenile hormone analogue Stauffer R-20458 (6, 7-epoxygeranyl (p-ethyl) phenyl ether) at various concentrations. Flies were reared on artificial diets and were tested within 48 hours after ec1osion. A definite dosage-efficiency correlation was observed and abnormalities in addition to death before pupation and emergence was recorded in treated larvae.
Two Pauropodidae Species (Myriapoda, Pauropoda) from the Subantarctic Crozet Islands
Authors: Scheller Ulf 
Published: July 2010

AbstractPauropoda (Myriapoda) are reported for the first time from the subantarctic islands. The study is based upon a collection from the Crozet Islands brought together by Dr. Lewis Davies, Durham. Two species were found, both new to science. They belong to the genera Pauropus and Stylopauropoides, the former having a world-wide, the latter a restricted southern distribution. The new species of this genus is closely related to one South American and one Australian species.

Revision of the North European Species of Cosmetopus Becker (Dipt. Scatophagidae)
Authors: Andersson Hugo 
Published: July 2010

AbstractLectotypes are designated for Cordylura dentimana Zetterstedt, 1838, Cordylura fulvipes Zetterstedt, 1838, Cosmetopus bergrothi Becker, 1900, and Cosmetopus simplicipes Becker, 1900. C. fulvipes Zett. is found to be a synonym of C. dentimana Zett. (n. syn.). The opinion that C. bergrothi is a synonym of Cosmetopus longus (Walker, 1849) and that C. simplicipes Beck. should be treated in a separate genus, Pleurochaetella Vockeroth, is confirmed. Cosmetopus ringdahli n. sp. is described and figured on material from Sweden and Finland. Distinctive characters of the other species are discussed and partly figured.
Observations on the Luminescence of the Larval Glowworm, Lampyris noctiluca L. (Col. Lampyridae)
Authors: Dreisig Hans 
Published: July 2010

AbstractThe larval luminescence in L. noctiluca consists in a glow lasting for several seconds (average 7.3 sec.) emitted at irregular intervals while the animal is crawling about during the active period at night. In the adult female the glow is continuous often for several hours. Also some larvae in the last instar were able to glow continuously for hours. Onset of activity in the larvae occurred at a lower critical ambient illumination (6.85 log lux +10) than in adult females (10.10 log lux+10). The dispersion of onsets was greater in larvae than in females. The duration of luminescent activity in the field was ca. 5 hours and at experimental conditions ca. 8 hours. In thc field larvae were mostly seen during late summer, probably because of the low critical illumination, which was also the reason why activity was suspended on moonlit nights. The intensity of moonlight around full moon was ca. 8.00—9.00 log lux+10. In the discussion the following subjects are treated: The function of larval luminescence; the reaction of larvae to ambient illumination; and the difference between glowing and flashing.
Abundance of Tundra Arthropods in Spitsbergen
Authors: Bengtson Sven-Axel , Fjellberg Arne , Solhöy Torstein 
Published: July 2010

AbstractThe late summer abundance of higher taxonomic units of arthropods on different types of coastal tundra in Spitsbergen (approx. 79°N, 12°E) was assessed by means of suction sampling of vegetation and litter and soil samples. Acari and Collembola comprised 96—99 % of the total number of arthropods and some Araneae and Diptera and a few Hymenoptera were regularly recorded. The total abundance (ind./m2) varied between 42—63,000 on lichen covered tundra, 268,000 on wet moss tundra, and 518,000 on grassland. There were considerable similarities in the abundance of major groups of arthropods between the Spitsbergen tundra and high alpine grounds in southern Norway, although in the former area some groups were absent.
The Concept of Oligophagy and the Natural Habitats and Host Plants of Papilio machaon L. in Fennoscandia
Authors: Wiklund Christer 
Published: July 2010

AbstractIn this paper a hypothesis is advanced according to which oligophagous insects have adopted two distinct strategies of habitat/host plant utilization, (1) a "monophagic strategy" being favoured in predictable habitats, making it possible to maximize reproductive success on one host plant per habitat only, (2) a "polyphagic strategy" being compulsively adopted in unpredictable habitats where two or more host plants per habitat have to be utilized for the maintenance of the species. For a partial preliminary test of this hypothesis the natural habitats and host plants of Papilio niachaon in Fennoscandia were investigated. The results indicate that (1) the predictable formations of inland wet-lands and coastal foreshores are the most important habitats (2) Peucedanum palustre, Angelica silvestris, Angelica archangelica ssp. littoralis and norvegica are the dominant host plants and (3) P. machaon appears to have adopted a "monophagic strategy" of habitat/host plant utilization in the predictable habitat categories.

Chromosome Numbers and Notes on Testicular Morphology of some Lebanese Rhopalocera (Insecta: Lepidoptera)
Authors: Larsen Torben B. 
Published: July 2010

AbstractThe chromosome numbers of 54 Lebanese Rhopalocera are given. 11 of them represent species not previously studied, while 26 of the remainder are endemic subspecies (often very characteristic) of species studied elsewhere. The findings are compared to the existing body of knowledge. The karyology is found to be very stable over wide geographical areas and, therefore, chromosome counts are a useful taxonomical tool for many groups of Rhopalocera. The chromosome counts of species not previously studied generally fall within the expected range for the respective genera and families. A simplified technique for karyological studies through non-permanent squash preparations is outlined.

The Gyrinidae of the Bismarck Archipelago and the Solomon Islands (Coleoptera: Gyrinidae)
Authors: Brinck Per 
Published: July 2010

AbstractThree species of whirligig beetles occur in the Bismarck archipelago (Gyrinus sericeolimbatus Rég., Macrogyrus ovatus Ochs, and Dineutus neobritannicus Ochs). Nine species occur on the Solomon Islands, viz. G. sericeolimbatus Rég., D. heterandrus Ochs and the following species of Dineutus (Callistodineutus): bougainvilleanus Ochs, bufo n.sp., choiseulicola n.sp., cristobalensis n.sp., dispar Ochs, dispersus n.sp., and pagdeni Ochs. - The morphological spectrum of subgenus Callistodineutus is reviewed and the distribution pattern and the differentiation of the species analysed. Ten species (of 11) are endemic. The general character is Indonesian. The Callistodineutus have spread twice over the islands, resulting in an older eastern group and a younger western. The western species are associated with a former continuous land connection, severed about 10 000 years ago. A stage of secondary dispersal (exchange of species among the islands) is still in progress.
Review of genus-group taxa included in the genus Tychius Germar (Coleoptera: Curculionidae)
Authors: Clark Wayne E. 
Published: July 2010

AbstractReview of world genus-group taxa heretofore assigned to Tychiinae indicates that the subfamily should be delimited to include the genera Apeltarius Desbrochers, Dichotychius Bedel, Itychus Kissinger, Mecynopyga Pierce, Paragoges LeConte, Sibinia Germar, Tychius Germar, Xenotychius Reitter, and their subgenera and synonyms. The status and relationships of formally recognized genus-group taxa within the genus Tychius are reviewed. Henonia Pic and Miccotrogus Schönherr are newly placed in sonynymy with Tychius; Lepidotychius Penecke is considered a subgenus of Tychius. All known host plants of species of Tychius are members of the legume subfamily Papilionoideae. Species from South America and Australia described as Tychius were not correctly assigned and belong in other tychiine genera or in other subfamilies.

Revision of the notescens-group of the genus Micropsectra Kieffer, 1909 (Diptera: Chironomidae)
Authors: Wedal Lars Sä 
Published: July 2010

AbstractThe Palearctic species in the notescens-group of the genus Micropsectra Kieffer are revised. Six species are redescribed and three new species, Micropsectra lindebergi, M. montana and M. nepalensis are described. Lectotypes are designated for 19 species and a neotype is designated for M. insignilobus Kieffer. The females and pupae are included as far as they are known. - Morphologically some of the species are very similar. In one case the only morphological difference between two species is found in the females. An analysis, presented in graphs and tables, is given to make it possible to separate the males of M. insignilobus and M. lindebergi, two morphologically very similar species. Most of the species which are difficult to separate on morphological grounds have a marked difference in their ecology, thus making an identification possible. - Notes on the distribution and ecology of the species are given. - Keys to the males and pupae of the species in the notescens-group are presented.

Post-embryonic development of Lithobius forficatus (L.), (Chilopoda: Lithobiidae)
Authors: Andersson Göran 
Published: July 2010

AbstractThe larval stadia of L. forficatus are easily distinguished by the number of legs and are separated from all other Scandinavian species in having more than 2+2 teeth on the forcipular coxosternite. The variation during development in size, number of coxal pores, ocelli, antennal articles, teeth on forcipular coxosternite, spinulation, projections on tergites 9, 11 and 13, accessory apical claw on the 15 th pair of legs and genitalia are described. Also the difference between male and female and correlation with size within each stadium are given. The number of coxal pores is the best feature for separating the post-larval stadia of L. forficatus. There are probably 9 post-larval stadia in Sweden. The larva media (sensu Verhoeff) is an accidental stadium and only occasionally included in development.
