Over the past 14 years, the chemical hybridization agent SQ-1 (CHA-SQ-1) has been widely used for inducing male sterility in wheat heterosis in China. However, any indirect effects of CHA-SQ-1 on high trophic level of food chains (e.g., wheat pests) have not been tested. Therefore, we addressed the question, under laboratory conditions, by...

Many insects harbor heritable endosymbionts, whether obligatory or facultative, and the role of facultative endosymbionts in shaping the phenotype of these species has become increasingly important. However, little is known about whether micro-injected endosymbionts can have any effects on aphid clones, which was measured using various...

Previous data showed that the parasitoid wasp Aphelinus asychis was more successful on Sitobion avenae clones artificially infected with different strains of Regiella insecticola compared to the same clones lacking facultative symbionts. To test whether this resulted from a specific interaction between the aphid and symbiont genotype, we used...

In recent decades, man-made electric fields have greatly increased the intensity of electrostatic fields that are pervasively present in the environment. To better understand the physiological alterations exhibited by herbivorous insects in response to changing electric environments, we determined the activities of anti-oxidative enzymes and...
