Rearing and release technology of two natural enemies
(Cryptolaemus montrouzieri and Aenasius bambawalei) for the management of cotton mealybug
Abstract
Cotton mealy bug (Phenacoccus solenopsis Tinsley) is a serious threat to sustainable production of cotton in Pakistan. Biological control is known one of the best strategies for its control. The C. montrouzieri and A. bambawalei under laboratory conditions was successfully reared at 70% relative humidity and 28°C temperature. The consumption of higher instar/adults /more pairs reflected maximum effectiveness than earlier ones. Adults releases for C. montrouzieri and mummies with host for A. bambawalei had more impact on cotton mealy bug suppression and establishment of natural enemies. For quick control of pest, farmers of developing countries rely completely on pesticides. The pesticides not only kill pests but also harmful for beneficial fauna present in the field. The biological based IPM is the most effective and environment friendly tactic to manage this pest insect.
This study will not only provide baseline but may also be proved very effective in conserving natural enemies and keeping hazardous chemicals away from the environment in the long run.
