Pyrethroid resistance and its inheritance in a field population of Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae)
The convergent lady beetle (CLB), Hippodamia convergens (Guérin-Méneville), a species widely distributed and used in biological control, has exhibited high survival under field and laboratory conditions when treated with field rates of the pyrethroid k-cyhalothrin, a highly unusual phenomenon for a natural enemy. This work investigated and characterized the phenomenon of pyrethroid resistance i...
متن کاملDeterminants of acute mortality of Hippodamia convergens (Coleoptera: Coccinellidae) to ultra-low volume permethrin used for mosquito management
There are relatively few experimental studies and risk assessments of the effects on non-target insects from ultra-low volume (ULV) insecticides used for management of adult mosquitoes. Therefore, we evaluated factors that may influence the ability of an insect to intercept the insecticide at the time of application by using Hippodamia convergens (Coleoptera: Coccinellidae) in field bioassay ex...
متن کاملA Comprehensive Selection of Reference Genes for RT-qPCR Analysis in a Predatory Lady Beetle, Hippodamia convergens (Coleoptera: Coccinellidae)
Reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) is a reliable, rapid, and reproducible technique for measuring and evaluating changes in gene expression. To facilitate gene expression studies and obtain more accurate RT-qPCR data, normalization relative to stable reference genes is required. In this study, expression profiles of seven candidate reference genes, including ...
متن کاملQuantitative evaluation of suitability of the greenbug, Schizaphis graminum, and the bird cherry-oat aphid, Rhopalosiphum padi, as prey for Hippodamia convergens (Coleoptera: Coccinellidae)
The nutritive value of two cereal aphid species, Schizaphis graminum and Rhopalosiphum padi, for Hippodamia convergens development was compared as pureand mixed-species diets and as suboptimum and ad libitum quantities. Comparisons were based on the following daily aphid quantities and combinations: 4 mg R. padi, 4 mg S. graminum, 3:1 mg mixture of R. padi and S. graminum, 2:2 mg mixture of R. ...
متن کاملEffects and tissue pathology of an unidentified microsporidium from the convergent lady beetle, Hippodamia convergens Guerin-Meneville (Coleoptera: Coccinellidae), on three non-target coccinellids By
A microsporidium from H. convergens was transmitted horizontally to three non-target coccinellids (Adalia bipunctata L., Coccinella septempunctata L. and Harmonia axyridis Pallas) under laboratory conditions. The effects of microsporidiosis on larval development, larval mortality, sex ratio, fecundity and adult longevity were examined. For all beetle species, larval development was prolonged as...
