Abstract

This paper presents the results of a survey conducted to survey and identify naturally occurring parasitoids of S. frugiperda attacking corn in Xalisco, Nayarit, Mexico. In November 2018, 104 first, second, and third instar S. frugiperda were collected at random from corn plots established in an experimental field of the Academic Unit of Agriculture of the Autonomous University of Nayarit. Of the 104 S. frugiperda larvae collected, 12 (11.5%) were parasitized. Of the parasitoids, Archytas californiae (Diptera: Tachinidae) accounted for 7.6% of the total mortality while Chelonus insularis (Hymenoptera: Braconidae) caused 3.8% mortality. Of the 92 remaining larvae, 18 died from unknown causes (17.3%) and 74 (71.1%) reached adulthood.
