Abstract The importance of secondary endosymbionts on the resistance to parasitoids is increasingly recognized. Compared with Hamiltonella defensa, our understanding of the role of Regiella insecticola in protecting hosts against parasitic wasps is not well documented. In this study, we conducted experiments to determine whether R. insecticola...

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...

BACKGROUND The complex interaction between plant viruses and their insect vectors is the basis for the epidemiology of plant viruses. The 'Vector Manipulation Hypothesis' (VMH) was proposed to demonstrate the evolution of strategies in plant viruses to enhance their transmission to new hosts through direct effects on insect vector behavior...

Previous studies have shown that Regiella insecticola modulated the parasitism rate in wheat aphid, Sitobion miscanthi. However, little is known about influences of the symbiont on wheat aphids by predators, the other important strategy used in biological control. Herein, we in the study examined effects of the R. insecticola on aphid...

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...

Abstract Background Aphids often harbor bacterial symbionts that confer resistance to biotic and abiotic stress. Previous studies have primarily examined the direct effects of symbiont infection on parasitoid success but less on aphid population dynamics under indirect parasitic situations, for example when exposed to parasitoid wasp odor....
