Effect of melatonin on the release of prothoracicotropic hormone from the brain of Periplaneta americana (Blattodea: Blattidae)
RICHTER K.*, PESCHE E., PESCHE D.
Eur. J. Entomol. 96 (4): 341-345, 1999
The occurrence of melatonin is known in nearly all organisms, but nothing is known exactly about its function outside of vertebrates. Long-term perifusions as well as short-term batch incubations of brains and moulting glands of the cockroach Periplaneta americana were used to identify the effect of melatonin on the release of prothoracicotropic hormone, a glandotropic neuropeptide in the brain, which stimulates the production of the moulting hormone ecdysone in the moulting gland. This is the first experimental evidence of a neurohormonal releasing effect of melatonin in the insect nervous system.

Plumbagin and azadirachtin deplete hemolymph ecdysteroid levels and alter the activity profiles of two lysosomal enzymes in the fat body of Helicoverpa armigera (Lepidoptera: Noctuidae)
JOSEPHRAJKUMAR A., SUBRAHMANYAM B.*, SRINIVASAN S.
Eur. J. Entomol. 96 (4): 347-353, 1999
The profile of hemolymph ecdysteroid was studied in the gram pod borer, Helicoverpa armigera, during larval-pupal transformation. The changes closely correspond to the developmental events occurring at metamorphosis. Two insect growth regulators, plumbagin and azadirachtin, significantly depleted the content and altered the profile of ecdysteroids at crucial stages, when applied at ED50 doses. The activity profiles of two fat body lysosomal enzymes, acid phosphatase and b-galactosidase, were also significantly affected by the insect growth regulators. It is suggested that plumbagin and azadirachtin treatments primarily modify...

Food remains in the guts of Coccinella septempunctata(Coleoptera: Coccinellidae) adults and larvae
Eur. J. Entomol. 96 (4): 355-364, 1999
From 1994-1997 the food of Coccinella septempunctata L. was investigated on the basis of gut dissections of adults and larvae collected in the field. Additionally, the gut contents of adults fed under laboratory conditions were investigated. The likelihood of recovering different prey types during gut dissection was variable, which will be illustrated by presenting some common prey fragments. The food eaten by adult C. septempunctata throughout a year was studied at a locality in Berlin-Staaken. Ladybirds were collected from March 1994 until November 1997 in different crops and habitats on roughly a monthly basis. Aphid feeding was detectable...
Effect of host plant on body size of Frankliniella occidentalis (Thysanoptera: Thripidae) and its correlation with reproductive capacity
DE KOGEL W.J.*, BOSCO D., VAN DER HOEK M., MOLLEMA C.
Eur. J. Entomol. 96 (4): 365-368, 1999
The effect of different host plants on Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) body size was investigated. Thrips from three different populations, from the Netherlands, Italy, and USA, achieved greater body sizes when reared on cucumber than on bean. The same thrips grew larger when reared on susceptible than on resistant cucumber. On the latter, reproduction was reduced, suggesting that smaller thrips have a lower reproduction. However, no evidence was found for a correlation between size and reproduction in experiments with thrips from four different populations, from the Netherlands, New Zealand, France, and USA that...
Host spatial pattern influences induction of parasitization by Trichogramma (Hymenoptera: Trichogrammatidae)
VOINOVICH N.D., UMAROVA T.Y., REZNIK S.Y.*
Eur. J. Entomol. 96 (4): 369-373, 1999
The influence of host intrapatch spatial distribution on parasitoid host acceptance behavior was investigated with Trichogramma principium parasitizing eggs of grain moth, Sitotroga cerealella. Single females were placed in Petri dishes, each containing 60 host eggs arranged either as a compact patch or partitioned into 60 or 12 clusters each consisting of 1 or 5 eggs, respectively. Partitioned patches provoked parasitization more often than compact patches. The percentage of ovipositing females (i.e., females parasitizing at least one of 60 host eggs) increased with the number of clusters, while it was independent of the intercluster...

Contributions of Monte-Carlo test procedures for the study of the spatial distribution of the European Vine Moth, Lobesia botrana (Lepidoptera: Tortricidae) in European vineyards
BADENHAUSSER I.*, LECHARPENTIER P., DELBAC L., PRACROS P.
Eur. J. Entomol. 96 (4): 375-380, 1999
The efficiency of Monte-Carlo procedures to test some hypotheses about the spatial patterns of larvae and damages of Lobesia botrana was studied. Two hypotheses were tested to detect spatial heterogeneity and spatial dependence. The most practical implication is to provide an efficient sampling scheme. The study of the relationship between spatial patterns and grape availability was required to explain scales of spatial heterogeneity and population dynamics studies were needed to relate it to oviposition behavior. It was tested through a third hypothesis. We adapted Monte-Carlo simulation procedures for the analysis of exhaustive count data...
Diversity and abundance of insect herbivores collected on Castanopsis acuminatissima (Fagaceae) in New Guinea: Relationships with leaf production and surrounding vegetation
Eur. J. Entomol. 96 (4): 381-391, 1999
Insect herbivores were collected from Castanopsis acuminatissima (Fagaceae) at Wau, Papua New Guinea, by beating the foliage of 15 trees during four one-month sampling periods, each representing different leaf-flush events. The association of leaf-chewing beetles with C. acuminatissima was verified with feeding trials. Of 59 species of leaf-chewing beetles that were collected, 36 species could be used in feeding trials. Only 9 of these species fed on C. acuminatissima. A further 27 beetle species were tested in feeding trials but did not feed. Of these, 7 were specialists feeding on other tree species within the surrounding vegetation....

Genetic identity and relationship between four Anagrus species (Hymenoptera: Mymaridae) using RAPD analysis
CHIAPPINI E.*, SORESSI L., FOGHER C., ZANIRATO M.
Eur. J. Entomol. 96 (4): 393-400, 1999
Four species of Anagrus (A. breviphragma Soyka, A. incarnatus Haliday, A. fennicus Soyka and A. obscurus Foerster sensu Soyka), that live on Carex riparia Curtis (Cyperaceae) in uncultivated areas along the Po river in the Piacenza province in Italy were analysed using RAPD markers in order to investigate their genetic relationships. High levels of RAPD polymorphism were found in the genus Anagrus, which permitted the fingerprinting of the four species. Analysis of average genetic similarities within species and comparison with average values between species confirms that A. breviphragma, A....
Hybridisation between Aphis grossulariae and Aphis schneideri (Sternorrhyncha: Aphididae): An experimental approach
Eur. J. Entomol. 96 (4): 401-408, 1999
A. schneideri and A. grossulariae clones from southern Poland produced fertile hybrid eggs under experimental conditions. Established hybrid clones expressed normal parthenogenetic reproduction but bisexual generations were not obtained, though a few sexuales developed in some cases. Morphological features of A. schneideri and host-specificity of A. grossulariae tended to dominate in the majority of hybrid clones. Independent inheritance of the studied morphological characters and host specificity can therefore be presumed.
Present results do not exclude the possibility of natural hybridisation of studied aphid species....
Field observations, laboratory rearing and descriptions of immatures of the planthopper Hyalesthes obsoletus (Hemiptera: Cixiidae)
SFORZA R.*, BOURGOIN T., WILSON S.W., BOUDON-PADIEU E.
Eur. J. Entomol. 96 (4): 409-418, 1999
The cixiid planthopper Hyalesthes obsoletus Signoret is an efficient vector of the stolbur phytoplasma, the cause of various crop diseases. In the field, this monovoltine species feeds on a wide variety of woody and herbaceous plants. It overwinters as larvae on the roots of its host plants. During this study, we collected adults mainly from lavender (Lavendula angustifolia Miller), bindweed (Convolvulus arvensis L. and C. sepium L.), hoary cress (Cardaria draba L.), and occasionally from plantain (Plantago cynops L.), toadflax (Linaria striata L.), bedstraw (Galium verum L.),...

The male of Tetanoptera leucodactyla (Diptera: Sciomyzidae)
KNUTSON L.V.*, VALA J.-C.
Eur. J. Entomol. 96 (4): 451-457, 1999
The male of Tetanoptera leucodactyla Verbèke, a genus and species of Sciomyzidae known until now only from one female specimen from the Congo, is described, and the genus is more fully characterized. The external morphology is illustrated and the male genitalia are described and figured for the first time. The relationships of Tetanoptera to genera of the Sepedon group and certain other genera of Tetanocerini are discussed. Tetanoptera appears to be related to Verbekaria, and intermediate in an evolutionary lineage between the relatively primitive Tetanocera and the advanced Thecomyia.

Stimulation of locomotion in Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) is wing-morph independent and correlated with lipid mobilization by adipokinetic hormone
SOCHA R.*, KODRIK D., ZEMEK R.
Eur. J. Entomol. 96 (4): 459-461, 1999
The effects of 5 pmols of adipokinetic hormone (Lom-AKH-I) on both the locomotion and mobilization of lipids were studied in 10-day-old diapausing adult females of the short-winged (brachypterous) morph of Pyrrhocoris apterus (L.). The results revealed that AKH stimulation of locomotion in this bug is wing-morph independent. The stimulatory effect of AKH on locomotion was shown to be positively correlated with its effect on lipid mobilization.
