Interactions between Entomopathogenic Fungi and Entomophagous Insects

Advances in Entomology 2020年第3期8卷 130-146页

作者： Mohamed Samir Tawfik Abbas Plant Protection Research Institute Agricultural Research Centre Giza Egypt

Direct treatment of predators with entomopathogenic fungi (EPF) at different concentrations revealed that some species, like Beauveria bassiana and Metarhizium anisopliae, were found to have detrimental effects on all developmental stages of some predator species. Other species, like Numoraea rileyi and Paecilomycis fumosorosius, showed little or no effect on treated predators. Adult predators were found to avoid feeding on fungi-infected prey. EPF could be isolated from hibernating or field-collected coccinellids. Some studies indicated that combining a fungus with a predator could increase the rate of insect control in the field. As for parasitoids, this review indicates that the developmental stages of the egg parasitoids can develop successfully in host eggs treated with fungi. However, fungus-infected hosts negatively impact the development of larval parasitoids inside such hosts and this impact depends on the species and concentration of the fungus as well as the time between infection and parasitism. Some parasitoid females can discriminate between fungus-infected and uninfected hosts and do not parasitize the infected hosts. With appropriate timing, the parasitoids or predators could be combined with fungi for the biological control of insects in the field.

Biorational control methods for protection of stored grain legumes against bruchid beetles

引用

Agricultural Sciences 2013年第12期4卷 762-766页

作者： Takashi Yamane National Agricultural Research Center National Agriculture and Food Research Organization Tsukuba Japan

Bruchid beetles such as Callosobruchus maculatus are known to the storage pests of grain legumes and cause tremendous damage. The main method to protect from them is chemical insecticides or fumigants. But, they would cause some problems such as environmental pollution, hazard to health. So, it is necessary to develop the grain legumes protection methods or systems using less chemical insecticides or fumigants from the perspective of integrated pest management (IPM). In this paper, I review the works of legumes grain protection methods without chemical insecticides or fumigants especially for the natural parasitoids, essential oils and other methods recently developed.
