Studies on aggressiveness of parasitoids, as assessed by their parasitism against pests, used in biological-control programs are highly important to select the most suitable species and/or strain control insect pests. The present study investigated whether egg parasitoid Trichogramma galloi Zucchi, an efficient agent for sugarcane borer Diatraea saccharalis (Fabricius) Brazil, could be replaced...

bacillus thuringiensis strains were isolated from various soil samples collected from different regions of kahramanmaraş in turkey and were characterized by their colony morphology, pcr method with cryiab/ac, cryid, cry2 and cyt2 primers, and sds-page of crystal proteins with 130-140 and 60-70 kda molecular weights. plasmid profiles of selected isolates were also analyzed. among the cry genes s...

the green lacewing, chrysoperla carnea (stephens) is one of the important predators of many pests including helicoverpa armigera (hübner) and tetranychus urticae koch. in insectaries, the larvae of this predator are mainly reared on anagasta kuehniella egg. in this research, biological and life table parameters of c. carnea in feeding on a. kuehniella egg as a laboratory prey and two natural pr...

The biology of Bracon hebetor Say (Hymenoptera: Braconidae) reared on fifth instars of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) (natural diet) and in vitro (artificial diet) was evaluated. Data on the number of instars, development time and food intake were collected, and histochemical tests were conducted to detect proteins and lipids in the parasitoid's digestive tract. The data ...
