A female-biased sex ratio is considered advantageous for the cytoplasmic elements that inhabit sexually reproducing organisms. There are numerous examples of bacterial symbionts in arthropod cytoplasm bias host toward females through various means, including feminization and male killing. Recently, maternally inherited RNA viruses belonging to family Partitiviridae were found cause killing moths flies, but it was unknown whether male-killing restricted or could be other taxa. Here, we...
Larvae of the bean blister beetle Epicauta gorhami Marseul (Coleoptera: Meloidae) feed on grasshopper eggs in soil and undergo hypermetamorphosis. This undergoes larval diapause fifth instar as a pseudopupa, form characteristic hypermetamorphosis meloid beetles. The effects temperature, photoperiod humidity development E. are examined population Miyazaki, Japan, using egg pods Locusta migratoria L. food. At lower temperatures (20 22.5 °C), all larvae become pseudopupae, regardless...
Abstract Larvae of the bean blister beetle, E picauta gorhami , feed on only grasshopper eggs and undergo hypermetamorphosis with pseudopupal diapause in fifth instar. Whether . larvae enter or pupate directly from fourth instar is controlled by temperature photoperiod. In nature, are confronted a significant variation availability food, suggesting possibility that feeding conditions may also affect incidence. Here, we addressed this issue changing under 16 h light : 8 dark (LD 8) at 25°C....
Geographical variations in the threshold of environmental cues for diapause induction are important understanding life history strategy insects. Larvae bean blister beetle, Epicauta gorhami (Coleoptera: Meloidae), feed on grasshopper eggs and undergo hypermetamorphosis. They normally enter as a pseudopupa (fifth instar). However, when larvae reared under long-day high-temperature conditions, they do not pseudopupal but pupate directly from fourth instar. In addition, this insect is known to...
