Mass rearing and augmentative releases of the native parasitoid Chouioia cunea for biological control of the introduced fall webworm Hyphantria cunea in China
Successful releases of H. cunea pupae indicate that an introduced pest species can also be controlled by the mass-rearing and release of native parasitoids in the country of introduction.
(R)‐(+)‐limonene, kairomone for Dastarcus helophoroides, a natural enemy of longhorned beetles
Both sexes showed attraction to wood with larval tunnels and larvae frass, and chemical cues involved in host location by Dastarcus helophoroides were investigated in a Y‐tube olfactometer.
Parasitism and olfactory responses of Dastarcus helophoroides (Coleoptera: Bothrideridae) to different Cerambycid hosts
Results showed that different D. helophoroides populations displayed different olfactory responses to larval frass from different longhorned beetle species, and must be taken into consideration when implementing biological control programs for different species of l Longhorned beetle.
Evaluating host location in three native Sclerodermus species and their ability to cause mortality in the wood borer Aromia bungii (Coleoptera: Cerambycidae) in laboratory

This study provided supporting evidence that young A. disparis males show more aggression likely because of their resource holding potential and sexual attractiveness decline with age, and the frequency and intensity of fighting significantly decreased with male age.
Monoterpenes from Larval Frass of Two Cerambycids as Chemical Cues for a Parasitoid, Dastarcus helophoroides
Kairomones for two populations of D. helophoroides that parasitize A. glabripennis and A. swainsoni were studied to provide information about the co-evolution of the species, its host, and host-food trees.
Male-male lethal combat in the quasi-gregarious parasitoid Anastatus disparis (Hymenoptera: Eupelmidae)
By comparing the frequency of received attacks between injured and non-injured males, it was found that the former were more vulnerable to attack and death that occurs as a result of A. disparis combat may be the cumulative effect of injuries sustained over repeated competitive encounters.
Fitness‐related offspring sex allocation of Anastatus disparis, a gypsy moth egg parasitoid, on different‐sized host species
It is indicated that host egg size decisively influenced the body size and sex ratio of the parasitoid offspring of Anastatus disparis and that larger hosts, especially the largest eggs of Antheraea pernyi Guérin‐Méneville (Saturniidae), might increase the fitness of A. disparis.

Overall, both sperm depletion and decreased fecundity played a role in determining the sex ratio of progeny from older mothers, suggesting that the increase in sex ratio amongst offspring was mainly due to decreased fertility in older maternal A. disparis.
Olfactory response of Dastarcus helophoroides (Coleoptera: Bothrideridae) to larval frass of Anoplophora glabripennis (Coleoptera: Cerambycidae) on different host tree species
Larval frass from six different host tree species varied in attraction to D. helophoroides adults, andfrass from one host species, Acer negundo, showed no attraction at all, which increases the understanding of the co-evolution between this parasitoid, its host, and host food trees.
