چکیده

the flour moth, ephestia kuehniella zeller and indianmeal moth, plodia interpunctella (hubner) are reported as important pests of stored products in many countries throughout the world. in recent years harobracon hebetor (say) wasp has been employed as a biological control agent of the moths' larvae in peanut warehouses as well as in packaged cereal products. in this study the functional responses of h. hebetor to larvae of flour moth and indianmeal moth were compared across a range of host densities (1, 2, 4, 8, 16 and 32 larvae/arena) and under some controlled conditions of 25±1°c, 65±10 rh and 14: 10 h (l:d). the resulting data were appropriately fit to type iii functional response models in two parasitoid – host interactions, namely: (1) h. hebetor to last instar larvae of flour moth (b = 0.0327 h-1 and th = 1.061 h), and (2) h. hebetor to last instar larvae of indianmeal moth (b = 0.0296h-1 and th = 1.045 h). the b value of h. hebetor to different densities of flour moth larvae was significantly greater than that of indianmeal moth larvae; whereas the handling time (th) of h. hebetor to larvae of flour moth was not significantly different as compared with the indianmeal moth larvae. these results indicate that h. hebetor was the preferred larvae of flour moth in comparison with indianmeal moth larvae.

The reproductive performance of the parasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) against the moths Anagasta kuehniella Zeller and Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) was studied in the laboratory. The analysis was based on the comparison of parasitoid's life table parameters related to those of its hosts at various conditions of host density (daily supply o...

Food characteristics strongly regulate digestive enzymatic activity of insects through direct influences on their midgut mechanisms. Insect performance is better on diets that contain nutrients in proportions that fit its digestive enzymes. Little is known about the influences of rearing history on parasitism success of Habrobracon hebetor Say. This research focused on the effect of nutrient re...

Phenoloxidase in larvae of Plodia interpunctella (Lepidoptera: Pyralidae): molecular cloning of the proenzyme cDNA and enzyme activity in larvae paralyzed and parasitized by Habrobracon hebetor (Hymenoptera: Braconidae).

Phenoloxidase (PO) is a major component of the insect immune system. The enzyme is involved in encapsulation and melanization processes as well as wound healing and cuticle sclerotization. PO is present as an inactive proenzyme, prophenoloxidase (PPO), which is activated via a protease cascade. In this study, we have cloned a full-length PPO1 cDNA and a partial PPO2 cDNA from the Indianmeal mot...
