Biological Parameters of Spodoptera frugiperda (J. E. Smith) under Laboratory Conditions

Abstract

The fall armyworm, <em>Spodoptera frugiperda </em>(J. E. Smith) is a highly notorious lepidopteran pest which is causing severe economic loss in different crops, especially maize. A study was conducted to know the biology of <em>S. frugiperda </em>on maize during July-December, 2019 under laboratory conditions at the Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur. The mean incubation, larval, pupal, pre-oviposition, oviposition and post-oviposition period were observed to be 3.30, 16.97, 8.96, 3.47, 2.96 and 6.13 days, respectively. The mean adult longevity of male and female was 10.67 and 13.00 days. The mean total life cycle was recorded to be 37.68 days. The average fecundity was 1662 eggs. Various morphometric data were also recorded.
