Abstract
The predatory mite, Blattisocius dentriticus (Berlese) (Blattisociidae) was propagated by feeding on eggs of three different types of pests, Lepidoglyphus destructor (Shrank) (Glycyphagidae), Goheria fusca (Oudemans) (Labidophoridae) and khabra bettle, Trogoderma granarium Everts (Dermestidae) under laboratory conditions at 30±2°C and 60% RH. The predator has shown promising traits for mass rearing by stored wheat pests. The results revealed that the longest predatory mite longevity (33.18& 27.7 days), when fed on eggs of G. fusca for females and males, respectively. Whereas, the high fecundity averaged 78 eggs through an oviposition period of 20.5 days when the predator fed on eggs of L. destractor while the lowest fecundity on eggs of labidophorid mite, G. fusca was (53.7 eggs) during oviposition period averaged (25 days). Significant differences between three wheat pests were noticed. In studing population growth parameters, The highest intrinsic rate of natural increase (rm) was reached as 0.197 individuals/female/day when fed on eggs of L. destractor which considered as the ideal prey for this mite followed by eggs of T. granarium was reached 0.143 ind./female/day while lower rm value was 0.112 ind./female/day that obtained when feeding on eggs of G.fusca. Time for population doubling was determined as (3.51, 4.84and 6.18 day) at different studied prey, respectively. It was concluded that the predatory mite can be maintained successfully on the alternative food, Acaridida species; L.destuctor, G.fusca and insect T. granarium for the mass-production of B. dentriticus as biocontrol agent for wheat pests in field in future. These results suggest that augmentative release of this predator would offset the lower rm of the predator, there by contributing to the control of mite pests. Combined with the benefit of early releases determined in companion studies, future field studies with B. dentriticus are being planned.
