A comparative study of biology and morphometrics of two different species of Earias on okra crop

Abstract Okra shoot and fruit borers, Earias insulana vittella are the major pests of economically important crops like okra cotton. It is to understand pest biology ecology before initiating control measures, however little known about their comparative on okra. Therefore, we studied biometrics E. in laboratory conditions fruits recorded duration different life stages along with morphological parameters, differentiate both species. Oviposition was comparable species, however, incubation period oviposition shorter vittella. Although incubation, oviposition, post-oviposition were at par but there a significant difference larval pupa periods. Total cycle being significantly longer case (13.8 days), while its pupal (8.5 days) comparision (9.9 . Sex ratio as 1:0.72 1: 0.61 (male: female) respectively. Both species slightly terms parameters. This study provides basic knowledge these that may be helpful formulating IPM strategies against them well
