Popis: Biological control strategies capitalise on natural mechanisms such as predation and parasitism to reduce the need for chemical applications to control insect pests. In Canada, the parasitic wasp Diadromus pulchellus Wesmael (Hymenoptera: Ichneumonidae) is being investigated for its use in the biological control of an invasive crop pest, the leek moth, Acrolepiopsis assectella (Zeller) (Lepidoptera: Acrolepiidae). Large numbers of insects will be needed for releases to ensure that populations of D. pulchellus establish quickly and impact leek moth populations. Since the current culture is not producing the number of insects required for large-scale releases, the accumulation and storage of D. pulchellus might be a viable option to obtain ideal numbers. Currently, little is known about the optimal conditions for the long-term storage and release of D. pulchellus, which overwinter in nature as adults. Using insects from the active culture, the effect of intermittent, short-term warming on cold-stor...
