Qualitative and Quantitative Prey Requirements of two Aphidophagous Coccinellids, Adalia tetraspilota and Hippodamia variegata
The suitability of two prey species, Aphis pomi De Geer (Hemiptera: Aphididae) and Brevicoryne brassicae (L.), for two generalist aphidophagous coccinellids, Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) and Hippodamia variegata (Goeze), at various abundance levels was investigated under laboratory conditions. While both A. pomi and B. brassicae were found to be suitable, the predators...
متن کاملComparative genetic studies of native and introduced Coccinellidae in North America
During the past four decades, several species of aphidophagous Coccinellidae became established in North America, including Coccinella septempunctata, Harmonia axyridis, Hippodamia variegata, and Propylea quatuordecimpunctata. After their establishment, unknown circumstances favoured a rapid increase in population densities and distribution of H. axyridis and C. septempunctata at localities hun...
متن کاملlong-term cold response in overwintering adults of ladybird hippodamia variegata (coleoptera: coccinellidae)
hippodamia variegata is an efficient and most abundant predatory coccinellids in many countries. understanding the ability of long-term low temperature survival in beneficial insects can be used to make better predictions about subsequent abundance and hence the biological control potential in the next spring and summer. so in this study, effects of long-term temperatures were investigated on m...
متن کاملdevelopmental and biochemical effects of hexaflumuron and spirodiclofen on the ladybird beetle, hippodamia variegata (goeze) (coleoptera: coccinellidae)
the ladybird beetle, hippodamia variegata (goeze) (coleoptera: coccinellidae) is one of the most important natural enemies of the common pistachio psylla, agonoscena pistaciae burckhardt and lauterer (hemiptera: psyllidae). the effects of hexaflumuron and spirodiclofen were investigated on development and carbohydrates and total lipid contents of 4th instar larvae of h. variegata. the insectici...
متن کاملIntraguild Predation Responses in Two Aphidophagous Coccinellids Identify Differences among Juvenile Stages and Aphid Densities
(1) Intraguild predation (IGP) can occur among aphidophagous predators thus reducing their effectiveness in controlling crop pests. Among ladybirds, Coccinella septempunctata L. and Hippodamia variegata Goeze are the most effective predators upon Aphis gossypii Glov., which is an economically important pest of melon. Understanding their likelihood to engage in reciprocal predation is a key poin...
