Diapause variation is a key factor affecting the development and success of parasitoids employed as biological control agents. Trichogramma dendrolimi Matsumura is mass-reared for biocontrol purposes in several countries around the world. Here we investigated the rate of diapause induction in three populations of T. dendrolimi from different...

BACKGROUNDTrichogramma dendrolimi Matsumura is widely used as a biological control agent for control of lepidopteran agricultural pests in China and can be successfully reared using the large eggs of the Chinese silkworm, Antheraea pernyi. In this study, biological parameters of diapaused, non-diapaused, and cold-stored T. dendrolimi were...

Host quality varies with size, age, and species, and influences the parasitism preference of parasitoids and the fitness of their offspring. However, it is still unclear whether parasitoids have the ability to recognize fertilized and unfertilized host eggs. We studied the performance of three Trichogramma species, T. japonicum, T. chilonis,...
