The life history, behavior and morphology of the immature stages of Enochrus quadripunctatus Herbst from Iran are studied. The results of the work on the life history and behavior of this species in the immature stages and as newly-emerged adults have been presented as part I. The morphology of the egg cases, larvae, pupae, and the male genitalia of the adult is covered in the present work....

A key molecule in the pathogenesis of Alzheimer's disease (AD) is a 42-amino acid isoform of the amyloid-β peptide (Aβ42), which is the most toxic element of senile plaques. In this study, to develop an edible, safe, low-cost vaccine for AD, a cholera toxin B subunit (CTB)-Aβ42 fusion protein was successfully expressed in silkworm pupae. We tested the silkworm pupae-derived oral vaccination con...

Species of the Simulium (Simulium) melanopus species-group in Sabah are taxonomically revised by examining type specimens of S. (S.) crassimanum S. (S.) laterale, and S. (S.) nigripilosum, all described from females by Edwards in 1933, and newly collected samples from the vicinity of Mt. Kinabalu. The females of these three species are redescribed, and their males and pupae are described for th...

Diapause is a programmed developmental arrest that has evolved in a wide variety of organisms and allows them survive unfavorable seasons. This developmental state is particularly common in insects. Based on circumstantial evidence, pupal diapause has been hypothesized to result from a cessation of prothoracicotropic hormone (PTTH) secretion from the brain. Here, we provide direct evidence for ...

The vertical migration of N. carpocapsae infective juveniles applied to the soil surface or introduced 14 cm below the soil surface was studied in four different soil types (pure silica sand, coarse sandy loam, silty clay loam, and clay). The percentage of juveniles able to migrate and infect wax moth pupae placed in the soil decreased as the percentage of clay and silt increased. Most nematode...

In order to determine the potential of various temperature treatments for disinfesting dried fruits and nuts of postharvest insect pests, e>qx>sure times for 50, 95 and 99% mortality in navel orangeworm eggs and pupae and Indiaruneal moth pupae were estimated. For navel orangeworm eggs, 99% mortality was achieved with a.-posure times of 194 minutes at 45°C and 14 minutes at 49°C. Navel orangewo...

This study describes assemblages of predatory ground beetles in native birch forest and derived blueberry farms on the Lower Mainland of British Columbia and investigates their role in the successful biological control of winter moth (Operopthera brumata L.) by the parasitoid Cyzenis albicans Fall ! en. Pitfall traps at four sites in 1991 and 1992 indicated that natural birch forest was dominat...
