Authors: Stratopoulou Ε.Τ. , Kapatos Ε.Τ. 
Published: November 2017

The action of parasites of Saissetia οleae (OIiv.) (Homoptera-Cοccidae) is studied in Corfu from 1980 in the framework of an ongoing project on the population dynamics of Saissetia οleae. Results obtained during the period 1980-1983 from 17 experimental sites indicate the following: a) the population of S. οleae increased in 1981 but from 1982 it declined to very low levels; following the overall decline of the host population, parasitization rates of third instar larvae (mainly by Μetaphycus helνolus Comp.) were relatively low and ranged from 2.1% to 6.7% for the autumn period and from 14.6% to 29.4% for the spring period; this does not minimize the possibility that Μetaphycus helνolus plays an important role on the regulation οf S. οleae populations; b) a considerable proportion of females of S. οleae is attacked during summer by Μetaphycus lounsburyi How. (an internal parasite on preovipositing females), Μoranila californica How. and Scutellista cyanea Μοtsch. (egg predators), but their significance upon the population system of S. οleae is not expected to be great. The action of Μetaphycus lounsburyi in spring, when the peak of the suitable stage occurs (i.e. fourth instar larvae), appears to be very low, at least for these three years. Its action is delayed and most of the specimens of this parasite emerge from ovipositing females in early summer. Among the species attacking S. οleae females, Μ. californica (recently introduced in Corfu) was the most abundant and it might be worthy to be introduced to other parts of Greece too.

First record of Polyphagotarsonemus latus (Banks 1904) (Αcari: Tarsonemidae) on greenhouse peppers in Crete
Authors: Roditakis Ν.Ε. , Drossos Ν.Ι. 
Published: November 2017

The broad mite, Polyphagotarsonemus latus Banks (Acari: Tarsonemidae), was first noticed on greenhouse pepper cv Cleopatra and Sonar in Ierapetra (Southeastern Crete) in 1984. During 1984 there were scattered mite infestations in a few greenhouses but in the following years it has become an increasingly important pest of peppers. The mite has been also found on cucumber cv Cnossos, aubergine cv Flaska and Solanum aviculare (indigenous of Amazonios) in the greenhouses of the Ierapetra Experimental Station. It atta­cks the growing points, young foliage, stem flowers and fruits. The growing points and bud are distorted, the young leaf margins down curl, the apical leaves crinkle, the leaf veins fuse and distort and the color changes to dark green, the fruits and stem crack and turn russet, mis-shape resembling like a fruit or stem scab and finally the small leaves and flowers fall off. Severely affected plants have little or no young growth, remain stunt and all fruitlets are aborted. The general look of the infested plants is similar to those affected by hormone weedkiller. Affected plants could not recover easily and the symptoms persisted for many weeks in spite of the acaricide treatments applied by the growers. In an artificial infestation of young pepper plants cv Sonar by 100-200 individuals, the symptoms of broad mite damage appeared in eight to ten days under growth chamber conditions (24±0.5°C, 60±5% R.H., 12.000 Lux for 16 hours daily).In Greece, the broad mite was first recorded on cotton leaves in 1969 and later on citrus trees. In Britain, it causes serious problems since 1978. It has been also noticed in several other countries of Europe. The spread of P. latus in many greenhouse plants in Britain was caused by the absence of acaricide treatments in green­houses where biological control against the two spotted spider mite Tetranychus urticae was ap­plied and the predator Phytoseilus persimilis was introduced by French bean leaves which was a recorded host of broad mite. The female longevity varies between 7-18 days depending mainly on temperature. The mean number of eggs/female is 40-50. The life cycle of broad mite is completed in 441, 205 and 98 hours at 14, 24 and 30°C, respectively. The developmental rate of various stages of the mite increased with the temperature but declined at about 35°C. The broad mite has been recorded on a wide range of hosts: tea plant, beans, tomatoes, cucumber, pep­pers, aubergines, citrus, zerbera, fuchsia, jasmin­um, magnolia, cotton, jute, coffee, avocado etc.
Larval development and timeliness of pupation in the laboratory of the navel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Phycitidae), on certain diets, under various Ρhοtoperiοd, tempera­ture, aeration and humidity conditions
Authors: Tzanakakis Μ. Ε. , Barnes Μ. Μ. 
Published: November 2017

Development of larvae of the navel orangeworm, Arn.ielois transitella (Walker) (Lepidoptera: Phycitidae), was studied under various photoperiods, temperatures and larval diets, in an effort to induce dormancy. Ready – to – batch eggs or neonate larvae were placed in transparent vials half – full of diet. Fully grown larvae not pupating within 14 days at 26.7oC and L:D 16:8 were considered as being in dormancy. With artificial larval diets containing bran, yeast, vitamins, and fortified or not with a high protein cereal and egg yolk, none of the treatments induced dormancy to a substantial percentage of laboratory stock or wild larvae. With dry walnut meats, larval growth was slower and survival much lower than with the artificial diets. With walnut meats, when eggs were incubated at 32.2oC and L:D 0:24, a certain percentage of grown larvae of the laboratory stock underwent dormancy when grown as larvae under the conditions that follow: 40% at 21oC and L:D 12:12, 17% at 21oC and L:D 0:24, 19% at 26.7oC and L:D 16:8, and 22% at 26.7oC and L:D 0:24 for the first 14 days than at 21oC and L:D 8:16 for the rest of larval life. When both embrya and larvae developed at 21oC and L:D 0:24, 17% of the larvae underwent dormancy. Yet, the relatively small number of grown larvae in the groups fed walnut meats suggests further work for the occurrence of dormancy in this insect to be proven. No larvae developed on straight brewers’ yeast powder. Straight soybean flour or 9:1 and 7:3 mixtures of it with yeast powder allowed the production of grown larvae, pupae and adults of normal appearance. The rate of larval growth on the soy:yeast diets was significantly slower than on a reference diet. At 26.7oC, a L:D 16:8 photoperiod was as good as a 14:10 one. Continuous darkness resulted in significantly reduced yield in adults and rate of larval growth. High relative humidity on the surface of the diet allowed excessive growth of fungi on and in the soy:yeast diets and resulted in a much faster larval growth. Larvae developed well on dry walnut meats and in cracked dry and water-soaked walnuts. Inside the walnuts the rate of larval growth was uneven, some larvae being still fairly small on the 53rd day at 26.7oC, while the majority was fully grown or had already pupated.
Characteristics of infestation of olive trees by Prociphilus oleae (Le­ach ex Risso) (Homoptera: Pemphigidae)
Authors: Tzanakakis M. E. , Prophetou-Athanasiasdou D. Α. 
Published: November 2017

A widespread infestation of olive trees in and near the city of Thessaloniki by Prociphilus oleae (Leach ex Risso) (Homoptera: Pemphigidae) was observed in 1988. Colonies including immatures and young slate adults were observed as late as early June. Infested trees were abundant along the streets of the Kalamaria section of the city. Infestations were also recorded 12 Km to the south and 75 Km to the southeast of the city, as well as on the island of Thassos, 200 Km to the east. Most infested trees had broad leaves and dense foliage, as well as scars, fissures, or other cavities on the trunk and limbs, and were shaded during part of the day by other trees or neighboring buildings. Compact colonies of the aphid occupied usually the basal part of 2 to 3-year old shoots at various heights in the trees up to 4 m, and mostly 1.5 to 2.5 from the ground. Usually there was one colony per shoot, and exceptionally up to 5.

First record and occurrence of Μacrosiphum euphorbiae (Thomas) (Homoptera: Aphididae) on cotton in Central Greece
Authors: Lykouressis D.P. 
Published: November 2017

The potato aphid, Macrosiphum euphorbiae (Thomas), is a highly polyphagous species on secondary hosts feeding on over 200 plant species, but is especially found on Solanum tuberosum L. M.euphorhiae was first noticed on cotton (cv Zeta 2) at Thiva in central Greece in May 1988 during a study on the population dynamics of cotton aphids carried out in a cotton field in the above mentioned region. This species has been recorded on other host-plants in Greece. It resembles Acyrthosiphon gossvpii Mordvilko, a species which also colonizes cotton but has not been recorded yet in Greece. They can be distinguished from each other since the former has shorter siphunculi, hearing a zone of polygonal reticulation on their apices, than the latter. Moreover, it is easily distinguishable from Aphis gossypii Glover, Aphis fabae Scopoli and Aphis craccivora Koch, species which also colonize cotton. A. gossypii is the most important aphid species attacking cotton at Thiva region and has also been recorded previously on cotton by various authors. The species A. fabae and A. craccivora have also been recorded on cotton in Greece. M. euphorbiae was found in the first three samplings that occurred between mid and the end of May when plants were young. From early June and during the rest of the growing season this species was not found in the field. In a total of about 50 plants sampled in each sampling only a few individuals were found. The majority of aphids were alatae, representing 69, 60 and 43 percent of the population at the first. second and third sampling dates, respectively. Alatae started to reproduce on the plants after their alightment, since first and second instar nymphs were present even from the first sampli­ng which took place after the appearance of plants. However, the number of nymphs was kept low during the period M. euphorbiae was present, suggesting that this was possiblydue either to the partial unsuitability of the cotton variety as host or to the effect of the systemic insecticide, phorate which had been applied at sowing, but this needs further investigation. This species was found again in low numbers in another cotton field at Thiva region, from mid May to early June of 1989. The fact that this species was not found from early June onwards in both years reveals that cotton is only a temporary secondary host-plant, possibly not very suitable for aphid development and reproduction. However, cotton may play some role on the population dynamics of M. euphorbiae on subsequent crops and mainly on potatoes, a crop which is widely planted at Thiva region. This might be of particular con­cern because M. euphorbiae is a vector of several viruses.

Epithrix hirtipennis, a New Pest of Tobacco in Greece, with Notes on its Morphology, Bioecology and Control
Authors: Lykouressis D.P. 
Published: November 2017

The tobacco flea beetle, Epithrix hirtipennis (Melsheimer) (Coleoptera: Chrysomelidae) was first noticed on tobacco in Agrinio area in early May 1988. In the next year it was also found to attack tobacco in the same area. Heavy attacks were also recorded on eggplant while a low infestation was noticed on potato and pepper. To date this species is widespread in several areas of Phthiotis (Central Greece) where tobacco is grown developing quite large populations. The adult feeds on the leaves causing almost circular holes, usually 1-2 mm in diameter, and irregular shape ones when they are larger. The adult starts feeding usually from the upper surface of the leaves and to a lesser extent from the underside. When large numbers of adults are present, larger holes are caused on the tobacco leaves while in higher population densities, the whole lamina except of nerves can be eaten, leading to severe damage of the crop. The adult was usually found on the upper surface of the lower tobacco leaves. It showed a strong feeding preference for the lower then the upper leaves of tobacco, as well as plants of reduced growth. The latter preference could be taken into account in an integrated pest management programme for tobacco pests. E. hirtipennis is of nearctic origin, known in U.S.A., Canada, Cuba, Mexico, Guatemala, Panama, Colombia and pos sibly occurs in other areas of Central and South America. It is a polyphagous species attacking cultivated plants and weeds such as tobacco, eggplant, potato, tomato, pepper, Jimson weed, ground cherry, nightshade, horse nettle and to a lesser extent many other plants. In tobacco, one adult has been estimated that can eat leaf quantity equal to ten times of its own weight in a day. Therefore, it can lower both the quantity and quality of leaves. E. hirtipennis was unknown to European countries until 1983. The first record in Europe was on tobacco in the area of Benevento, in the Campania region, South Italy. Later, it was recorded in Toscana, whilst Sannino and Balbiani reported that it was already present in the provinces of Campania, Basilicata, Lazio, Puglia, Abruzzo, Toscana and Umbria; Toscana and Umbria are the last areas in which the species was recorded. After its appearance, it has progressively spread into South and Central Italy causing damage which depends upon tobacco type. The record of E. hirtipennis at first in Agrinio area and later in other areas of Central Greece reveals that it rather invaded West Greece through transport from Italy and has spread to other areas.

The application of an Integrated Control on Eggplant for the Greenhouse Whitefly, Triαleurodes vαporαriorum
Authors: Abdalla SAFEL DAWLA , Michelakis S. 
Published: November 2017

Integrated control of the greenhouse whitefly on eggplant, using physical (traps), chemical and biological methods, was tested. The mort efficient combination was the use of Quinomethionate and traps. Applaud and Actellic mixture was fairly effective in controlling the greenhouse whitefly. Biological control by the parasite Encarsia formosa (Gahan), resulted in moderate, but adequate control when combined with traps. Traps clone gave reasonable results. All treatments were effective in reducing whitefly population to a satisfactory low level, when compared to the untreated populations. Parasitoid/host release ratio play an important rote in the results of biological control using E. formosa. The higher relcase ratio of 4:1, parasitoid:host, gave the maximum parasitization percentage.
Comparisons Between Alate Aphids Caught in Υellow Water Traps and Aphid Populations on Tomato Plants
Authors: Lykouressis P. , Perdikis D. CH. , Chalkia CH.A. , Vardaki S. C. 
Published: November 2017

Aphid monitoring was conducted by means of yellow Moericke water traps placed in tomato fields in two different localities in Co Boiotia during the growing seasons in 1992 and 1993. Additionally, aphid population densities were estimated by plant sampling. Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulzer) were the only species which developed populations on plants. Regression analysis between the number of alates from traps with either the number of alates or the total aphid population on plants showed that there was no correlation in the case of M. persicae for both localities and years. However, there were significant relationships between the number of alates in traps and either the number of alates on plants (r2=0.83) or the total aphid population on plants (r2=0.69) for M. euphorbiae in 1992. In 1993, such significant relationships were not found for the latter species, most probably due to extremely low trap catches. Significant relationships were also found between alates in traps, during their immigration period, with either alates on plants (r2=0.93) or the total population on plants (r2=0.80) in M. euphorbiae in 1992.
Elecroantennogram Responses of the Cherry Fruit Fly Rhαgoletis cerαsi (Diptera: Tephritidae) to Naturally Occurring Volatiles

Published: November 2017

EAG responses of the cherry fruit fly, Rhagoletis cerasi (Linne) (Diptera: Tephritidae) were recorded in response to seventy-eight generally occurring plant volatiles and male cherry fruit fly volatiles. The test compounds are representatives of three major classes of organic compounds, aldehydes, ketones, and monoterpenes. No differences were observed in the degree of response between males and females, Carbon-chain length, unsaturation, and position of functional groups all have significant effect on the magnitude of EAG response.
