Abstract: Comparative genomic hybridization (CGH) with a probe mixture of differently labeled genomic DNA from females and males highlighted the W chromosomes in mitotic plates and the W chromatin in polyploid interphase nuclei of the silkworm Bombyx mori, the flour moth Ephestia kuehniella, and the wax moth Galleria mellonella. The overproportionate fluorescence signal indicated an accumulatio...

the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...

Crosses among the six semispecies of Drosophila paulistorum produce sterile male hybrids. This sterility is caused by an agent which has characteristics of a microorganism. It is pathogenic in a secondary host, the larvae of the Mediterranean meal moth, Ephestia kuehniella, and can be serially passaged in Ephestia, where it is lethal. The agent was passaged back into D. paulistorum, where it in...

In this study, the cry1Ab gene of previously characterized and Lepidoptera-, Diptera-, and Coleoptera-active Bacillus thuringiensis SY49-1 strain was cloned, expressed and individually tested on Ephestia kuehniella (Lepidoptera: Pyralidae) and Plodia interpunctella (Lepidoptera: Pyralidae) larvae. pET-cry1Ab plasmids were constructed by ligating the cry1Ab into pET28a (+) expression vector. Con...
