Genetic control strategies offer great potential for the sustainable and effective control of insect pests. These strategies involve the field release of transgenic insects with the aim of introducing engineered alleles into wild populations, either permanently or transiently. Their efficacy can therefore be reduced if transgene-associated fitness costs(More)
Development and evaluation of new insect pest management tools is critical for overcoming over-reliance upon, and growing resistance to, synthetic, biological and plant-expressed insecticides. For transgenic crops expressing insecticidal proteins from the bacterium Bacillus thuringiensis (‘Bt crops’) emergence of resistance is slowed by maintaining a(More)
Invasive species remain one of the greatest threats to global biodiversity. Their control would be enhanced through the development of more effective and sustainable pest management strategies. Recently, a novel form of genetic pest management (GPM) has been developed in which the mating behaviour of insect pests is exploited to introduce genetically(More)
Nowadays, heavy metal pollution has become more and more serious. Cadmium is one of the heavy metals that have caused serious pollution. Spodoptera exigua Hübner (Lepidoptera: Noctuidae), one of important agricultural pests, has broken out more frequently in recent years. In this study, accumulation at different developmental stages and excretion of Cd were(More)
