1. The parasitoid of the leaf miner , Pnigalio phragmitis Erdos, prefers the third instar to parasitizing.

2. The behavior of its parasitoid Pnigalio phragmitis Erdos was also studied.

3. Diglyphus isaea(Walker) was a parasitoid of several important Liriomyza spp.

3. try its best to collect and make good sentences.

4. The effect of predator, parasitoid, insect pest and neutral insect groups in the arthropod community in the weed habitat on the corresponding groups in the paddy habitat were varied.

5. The parasitoid chouioia cunea releaser is convenient for large-scale production, package, transportation and releasing.

6. Parasitoid wasps and flies use their long ovipositors to thrust their eggs into the eggs and bodies of other insects.

7. Parasitism is differentiated from the parasitoid relationship by the fact that parasitoids generally kill their hosts.

8. During foraging and oviposition, hymenopteran parasitoid females often compete for hosts with individuals of the same or different species.

9. HPLC was used to investigate whether spinosad applied to parasitized host larvae could reach parasitoid larvae developing inside the hosts.

10. This paper summarized Ectropis obliqua Prout s biological control researches from the point of mass rearing, pathogenic natural enemy, predator, parasitoid and pheromone.

11. Although early instar larvae were present in the host larval hemocoel, only one parasitoid survived to come out of host larva for pupation, killing the larva in the process.

12. Preadult experience can influence the antennal sensitivity of the parasitoid.

13. Encarsia bimaculata and Eretmocerus sp. nr. furuhashii are two dominant species of parasitoid parasitizing Bemisia tabaci in South China.

14. The host mortality after exposure were decreased with increase of the host age at exposure to the parasitoid.

15. But the artificial eggs, when painted with the scales of the host, can attract the parasitoid to complete the oviposition process.

16. Using trichloromethane as an extract solvent, the extract of the two pupae induced the female parasitoid to increase searching, staying and antennal examination behaviors.

17. Parasitoid wasps and flies use their long ovipositors to thrust their eggs into the eggs and bodies of other insects. Roughly 10 percent of all insect species are parasitoids.

18. In conclusion, in the late stage of parasitization, the parasitoid larva, with the help of teratocytes, utilized up most of the host nutrients for its own development and growth.

19. Trichogramma wasp, which can parasite eggs of many species of Lepidoptera, is the most widely used egg parasitoid wasp in world bio-control.

20. Their functions were discussed in reference to their morphology, distribution, and the electroantennogram responses of the parasitoid previously reported.

21. Nilaparvata lugens density and continuously feeding time obviously influenced the activity of volatiles emitted from rice plants attractive to the parasitoid.

22. These suggest that N. lugens infestation levels influence the host preference and performance of the parasitoid.
