Yansong Wang, Ping Gao, Jie Zheng, Hongran Li, more

Pest Management Science > 79 > 11 > 4501 - 4507

BACKGROUND The gut microbiota has an intimate relationship with insect hosts and this relationship can become complicated with parasitic organisms being involved with the host. To date there has been limited evidence for the relevance of parasitism of the host by parasitoids to host gut microbiota, especially in host insect predators. Here, our study examined gut microbiotas in larvae of the predaceous...

Agonistic responses to potential co‐foundresses in a cooperatively brooding quasi‐social parasitoid

Xiaomeng Guo, Bingying Zhou, Rina Zhao, Ling Meng, more

Ecological Entomology > 48 > 1 > 11 - 18

Sociality is not common among parasitoid hymenopterans, but members of the ectoparasitoid genus Sclerodermus (in the aculeate family Bethylidae) may form multi‐foundress groups, producing and tending a single brood (of combined parentage) on a large host until offspring maturity. While individual foundresses can benefit more from reproducing within groups rather than alone, recent studies have indicated...

Jincheng Zhou, Ling Meng, Baoping Li

BioControl > 2019 > 64 > 2 > 115-124

Non-reproductive effects of parasitoids on their hosts and their associated mechanisms are poorly known. We carried out laboratory studies to measure non-reproductive mortality (NRM) and reproductive mortality (RM) caused by two different larval parasitoids to the oriental armyworm Mythimna separata (Walker) that fed on either wheat or maize plants. We then examined non-lethal effects of the parasitoids...

Fitness consequences of body-size-dependent parasitism in a gregarious parasitoid attacking the 7-spot ladybird, Coccinella septempunctata (Coleoptera: Coccinellidae)

Haitian Song, Ling Meng, Baoping Li

Biological Control > 2017 > 113 > C > 73-79

Variation in body size of hosts and their parasitoids poses a significant challenge for gregarious parasitoid females to make their decisions to optimally utilize a range of hosts. In the present study, we investigated the combined effect of host size across successive host larval stages and maternal wasp size on fitness-correlated performances of offspring parasitoids, using the larval-pupal gregarious...
