Drugiai Lietuvoje tiriami jau seniai, tačiau dažniausiai tai buvo epizodiniai tyrimai. Yra mažai duoneų apie konkrečios vietovės drugių bendrijas. Šiame darbe aprašomi Ignalinos rajono, agrarinio kraštovaizdžio naktinių makrodrugių tyrimų metodai ir rezultatai. Tirti drugiai priklauso antšeimiams Geometroidea, Bombycoidea, Drepanoidea, Lasiocampoidea, Noctuoidea ir Hepialoidea. Tyrimų medžiaga buvo renkama 2008-2010 m. Antagavės ir Stagalėnų apylinkėse (Ignalinos rajonas), nuo gegužės iki lapkričio. buvo naudojama Jalo modelio šviesinė vabzdžių gaudyklė su Philips ML 160W lempa. Marinimui naudotas etilacetatas. Antagavėje buvo rastos 169 drugių rūšys, Stagalėnuose 201, surinkti iš viso 13244 individai. Stagalėnai yra Aukštaitijos nacionaliniame parke. Šiose apylinkėse rasta 33% visų parke žinomų drugių rūšių. Nenustatyta eudominantinių ir dominantinių rūšių. Gausiausios rūšys buvo Rivula sericealis (sudarė 3,89% visų bendrijos individų), Xestia (Megasema) c-nigrum (3,41%), Caradrina (Caradrina) morpheus (3,12%). 26 rūšys sudarė daugiau nei 1% visų bendrijos drugių individų. Gausiausios rūšys Antagavėjė buvo Noctua pronuba (7,96%) ir Caradrina morpheus (6,39%). Tai dominantinės rūšys šioje vietovėje. Didžiausias drugių rūšių ir individų gausumas buvo liepos mėnesį. / Lithuanian moths (Lepidoptera) were studied by various researchers for a long time, but mostly only episodic studies were carried on. There are little data concerning nocturnal Lepidoptera investigations of concrete district. Methods and results of nocturnal macrolepidoptera research in agricultural landscape in Ignalina administrative district are described in this work. Analyzed species belong to superfamilies Geometroidea, Bombycoidea, Drepanoidea, Lasiocampoidea, Noctuoidea and Hepialoidea. The material of nocturnal Lepidoptera was collected in Antagavė and Stagalėnai localities (Ignalina administrative district) during May and October 2008-2010. Jalas model automatic light trap with Philips ML 160W lamp bulb was used. Ethyl acetate was used as a killing agent. There were 169 moth species collected in Antagavė and 201 in Stagalėnai with the total number of 13244 individuals. Stagalėnai is in Aukštatija national park. In this village found 33% of the national park known species. There was no eudominants or dominants. The most abundant species were Rivula sericealis (species made 3,89% of all individuals in Stagalėnai), Xestia (Megasema) c-nigrum (3,41%), Caradrina (Caradrina) morpheus (3,12%). 26 macrolepidoptera species made more than 1% of all individuals. They characterise the community. Most abundant species in Antagavė were Noctua pronuba (7,96%) and Caradrina morpheus (6,39%). They are dominants in this territory. Greatest abundance of species and individuals was... [to full text]

We studied the Geometridae associated to Erythroxylum microphyllum. The samples were collected at each two weeks, during a year. Its was used the method of entomological umbrella. The larvae was grown in the laboratory, using the host plant as food. It occured 22 species of Geometridae arranged in 15 genus, 11 genus of Hymenoptera Parasitca and two Diptera Tachindae. The most common species that occured was Cyclomia mopsaria, whose relative abundance was 83%. Other Geometridae recorded were: Glena unipennaria, G. bipennaria, G. demissaria, G. brachia, Physocleora junctilinea, P. cariaria, Physocleora sp., Iridopsis fulvitincta, I. nigraria, Hymenomima amberia, Macaria regulata, Ischnopteris sp., Prochoerodes onustaria, Prochoerodes sp., Thyrinteina arnobia, Nematocampa sp., Melanolophia sp., Isochromodes, Semaeopus lunifera and Semaeopus vizaria. The Hymenoptera parasitoids were: Microcharops peronata, Charops sp., Metopius sp., Hyposoter sp., Mesochorus sp., Aleiodes sp., Distatrix sp., Meteorus sp., Protapanteles sp., Rasivalva sp., e Euplectrus sp. The Diptera Tachinidae were: Winthemia sp., and a Blondeliini species. The period of higher occurrence of larvae was between the end of rainy season and the begining of the dry season. At this same period, was recorded the lowest rate of parasitism. / Este trabalho foi realizado em área de cerrado, próximo a mata ripária. Foram estudados os Geometridae associados a Erythroxylum microphyllum. As coletas foram realizadas quinzenalmente, durante um ano por meio de guarda-chuva entomológico. As larvas foram criadas em laboratório, utilizando a planta hospedeira para alimentá-las. Ocorreram 22 espécies de Geometridae distribuídas em 15 gêneros, 11 gêneros de Hymenoptera Parasitica e dois Diptera Tachinidae. Dentre as espécies de Geometridae, a mais comum, com abundância relativa de 83%, foi Cyclomia mopsaria. Outros geometrídeos registrados foram: Glena unipennaria, G. bipennaria, G. demissaria, G. brachia, Physocleora junctilinea, P. cariaria, Physocleora sp., Iridopsis fulvitincta, I. nigraria, Hymenomima amberia, Macaria regulata, Ischnopteris sp., Prochoerodes onustaria, Prochoerodes sp., Thyrinteina arnobia, Nematocampa sp., Melanolophia sp., Isochromodes, Semaeopus lunifera e Semaeopus vizaria. Os parasitóides Hymenoptera foram: Microcharops peronata, Charops sp., Metopius sp., Hyposoter sp., Mesochorus sp., Aleiodes sp., Distatrix sp., Meteorus sp., Protapanteles sp., Rasivalva sp., e Euplectrus sp. Os Diptera Tachinidae foram: Winthemia sp., e Blondeliini. A época de maior ocorrência de larvas foi entre o final da estação chuvosa e o início da estação seca. Nesta mesma época, ocorreram os mais baixos níveis de parasitismo.
