Heat stress can limit the activity time budget of ungulates due to hyperthermia, which is relevant for African antelopes in ecosystems where temperature routinely increases above 40 °C. Body size influences this thermal sensitivity as large bodied ungulates have a lower surface area to volume ratio than smaller ungulates, and therefore a reduced heat dissipation capacity. We tested whether the ...

The geomagnetic field affects all living organisms on the Earth. In this study we investigated developmental and behavioral effects of rearing Mythimna separata in a near-zero magnetic (<500 nT) compared to local (approximately 50 µT). produced by Helmholtz coil system significantly lengthened larval pupal development durations, increased male longevity, reduced weight, female reproduction, rel...

Zoological Studies 42(2): 336-345. The pharmacological effects of calcium channel antagonists on the in vitro release of juvenile hormon...

Although many organisms show daily rhythms in their activity patterns, the mechanistic causes of these patterns are poorly understood. Here we show that host plant volatiles affect the nocturnal behavior of the caterpillar Mythimna separata. Irrespective of light status, the caterpillars behaved as if they were in the dark when exposed to volatiles emitted from host plants (either uninfested or...

In order to develop new biorational pesticides, ten new 6-substituted ester derivatives of Celangulin-V were designed and synthesized. The structures of the new derivatives were confirmed by IR, (1)H-NMR, (13)C-NMR and ESI-MS spectral analysis. Insecticidal activities of these compounds were tested against the third-instar larvae of Mythimna separata. Two derivatives (1.1, 1.2) showed higher in...

A new species of parasitoid wasp (Braconidae, Microgastrinae) from the kingdom Saudi Arabia (KSA) is described, Microplitis idreesae sp. nov. The genus reported for first time in Eastern province KSA. This host-parasitoid association documented country. attacks Mythimna Ochsenheimer (Lepidoptera, Noctuidae). Natural history information provided such as males with females, geographical location,...
