Control of Heliothis armigera with Trichogramma - selection of Trichogramma spp. and their quantitative relation to hosts

, : Control of Heliothis armigera with Trichogramma - selection of Trichogramma spp. and their quantitative relation to hosts. Natural Enemies of Insects Kunchong Tiandi 7(2): 63-69

The effectiveness of the egg parasites Trichogramma confusum T. closterae and T. dendrolimi in controlling the noctuid Heliothis armigera on cotton was assessed in field studies in China. Separate releases of each species at the rate of 30 000/mu resulted in rates of parasitism of 68, 54.3 and 45.3%, respectively. Mixed releases of any 2 species in the ratio of 1:1 at a rate of 30 000/mu resulted in slightly lower rates of parasitism than releases of each species alone.

Synaptosomes and plasma membrane preparations from brain of 30-day-old rats were incubated with glutaric acid at final concentrations ranging from 10 nM to 1 mM for the determination of glutamate uptake and binding, respectively. (3H)Glutamate upt...

We describe sex reversal in a phenotypic female with 46,XY and SRY gene. Evidence accumulated here in the Swyer's syndrome may provide a better opportunity to study aberrations of gonadal development in man.

The paper is devoted to study of the influence of short-term low-level microwave irradiation (6GHz, modulation 2 Hz, average intensity 0.015 mW/cm-2, exposure time 50 min) on some electrophysiological and hormonal parameters in rabbits. No reliabl...
