Emergence and survival of adults for 24 hwas compared forTrichogramma chilonis Ishii reared on eggs of Corcyra cephalonica (Stainton) adults whose larval growth and development had beenmonitored on broken grains of four different cereals: Þngermillet (Eleusine coracanaL.Gaertn), softwhitewheat (TriticumaestivumL), short-grainedwhite rice (Oryza sativaL.), anddurra sorghum (Sorghum bicolor L. Mo...

The issue of propagating parasitic insects in artificial food environments has been a challenge for researchers long time. Breeding one Trichogramma insect requires lot grain products and labor, it takes about 40-50 days 55-60 Bracon to reproduce. This study aimed develop technology the vitro reproduction trichogram, which are important entomophages control various agricultural pests. results e...

Intraguild predation (IGP) is common in food web when two natural enemies share the same resources and prey. It may affect the success or failure of a biological control attempt. The role of intraguild predation by Geocoris ochropterus Fieber (Heteroptera: Geocoridae) on Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) developed on eggs of Helicoverpa armigera (Hubner) (Lepidoptera:...

The environmental compatibility of a biological control agent is an important aspect of successful reduction of agricultural pests. Temperature fluctuations during the day have a strong influence on the performance of laboratory-reared parasitoids. In field conditions, Trichogramma (Hymenoptera: Trichogrammatidae) wasps are exposed to variable temperatures during their development, which has a ...

Laboratory experiments were conducted to evaluate the effect of some commercially available biopesticidal formulations, such as Bacillus thuringiensis var. kurstaki (2g/l), sphaericus(2g/l), Beauveria bassiana (5g/l), Metarhizium anisopliae Lecanicillium lecanii (5g/l) on Temperature Tolerant strain Trichogramma chilonis (TTT). Two sets conducted, in first experiment, all test biopesticides spr...
