developmental 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 کاملLaboratory Evaluation of the Toxicity of Proteus, Pymetrozine, Deltamethrin, and Pirimicarb on Lady Beetle Hippodamia Variegata (goeze) (col.: Coccinellidae)
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...
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 کاملCondition-dependent ejaculate size and composition in a ladybird beetle.
Sexually selected male ejaculate traits are expected to depend on the resource state of males. Theory predicts that males in good condition will produce larger ejaculates, but that ejaculate composition will depend on the relative production costs of ejaculate components and the risk of sperm competition experienced by low- and high-condition males. Under some conditions, when low condition lea...
متن کاملQualitative 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...
