bionomics of aphis gossypii glover and its predators coccinella septempunctata l. and hippodamia variegata goeze were studied in varamin (tehran province) during 11th may to 5th october 2006 on eggplant crop, with the interaction (density dependence) between the aphid and either of the predators determined. the reliable sample size (number of leaves) with a maximum variation of 6.73% was about ...

In this study, nine microsatellite loci were isolated and characterized from the seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae). The loci were validated and characterized using 20 samples collected from five Korean localities. These results indicate that some loci were highly variable in terms of number of alleles (2 to 13), heterozygosity (0.10 to 0.40), and p...

Dinocampus coccinellae (Schrank) is a braconid parasitoid of ladybird beetles (Coleoptera: Coccinellidae) and has exceptionally wide geographical host ranges. Based on published unpublished sources probably occurs throughout the temperate, subtropical tropical climatic zones, but some regions, such as sub-Saharan Africa (except its southernmost part) Malay Archipelago, have not so far been surv...

The implementation of an Integrated Pest Management (IPM) program requires selecting and using chemicals which are least harmful to natural enemies. In this study, the acute toxicity of the recommended field concentration of four conventional insecticides was evaluated in reference to the different life stages (L3, L4 and adult) of the variegated lady beetle Hippodamia variegata (Goeze) (Coleop...

Entomological collections are an invaluable source of data, due to the variety species they contain, capturing biodiversity a given time. Thus, entomology part Division Zoology Collection (Faculty Science, Department Biology), in Zagreb, established 1890, is important asset for all faunistic research and any overview historical changes composition, as well resource education young scientists. H...

common pistachio psylla, agonoscena pistaciae burckardt and lauterer (hemiptera: aphalaridae) is one of the economical pest among the pistachio orchards. the adonis' ladybird, hippodamia variegata (goeze) (col: coccinellidae) is one of the most prominent coccinellid predator in pistachio orchards. it is omnivorous and feed on aphids and psylla. functional response studies using a suitable ...
