Abstract

In Jan and Feb 2015, the tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), was found to have entered and established in the Malnad and Hyderabad-Karnataka Regions of Karnataka, India, where it is infesting tomato and potato crops. To our knowledge, this is the first record of T. absoluta in these regions of India. The incidence recorded appears to be comparatively small at some locations, but this damaging insect may spread to other regions of India and cause serious crop loss in the future. Probably, the introduced populations are resistant to various insecticides, and management of insecticideresistant populations poses additional problems.

 

Sumario

En enero y febrero de 2015, la polilla del tomate, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), se encontró que habia entrado y estableció en las regiones de Malnad y Hyderabad-Karnataka de Karnataka, India. Hasta donde sabemos, este es el primer registro de Tuta absoluta en estas regiones de la India. La incidencia registrada parece ser relativamente pequeña en algunos lugares, pero puede extenderse a otras regiones de la India y causar daños graves en el futuro. Es probable que las poblaciones introducidas son resistentes a diversos insecticidas, y el manejo de las poblaciones resistentes a los insecticidas plantea problemas adicionales.
