Abstract:

Hainan province is one of the invasion areas of Spodoptera frugiperda in China. In order to grasp the occurrence and prevention and control of S. frugiperda in Hainan, from April to July 2019, experts from Environment and Plant Protection Institute of the Chinese Academy of Tropical Agricultural Sciences conducted field investigations in Hainan province on the natural enemies of S. frugiperda in the main corn-growing areas of 18 cities or counties. In this paper, the parasitic egg mass, larvae and pupa collected in the investigation areas were placed under laboratory conditions for observation. Five species of parasitic wasp were found, among which the egg parasitoid was Telenomus remus Nixon and Trichogramma chilonis Ishii, and the larvae parasitoid was Microplitis pallidipes Szepligeti, and the pupa parasitoid was Tetrastichus howardi Olliff, and the egg-larva parasitoid was Chelonus formosanus Sonan.The main identifying characteristics and basic biological characteristics of the five parasitoids were reported. The natural control effect of the five parasitoids on the alien invasive pest was preliminarily made clear. Mastering the species of natural enemies of S. frugiperda in Hainan has important value for screening the natural enemies for controlling S. frugiperda.

Key words: Spodoptera frugiperda, parasitoids, morphological character, biological character
