Progress Reports

This study was designed to update the information about the present level of infestation of the occurrence of Helicoverpa armigera in major tomato growing areas and also to develop microbial control based strategies to prevent its further spread in new potential areas
Problem statement
The yield of tomato crop is invariably reduced by many factors and among these, responsible for hampering tomato yield; tomato fruitworm, Helicoverpa armigera is quite important all over the world

Survey and sampling of tomato fruitworm from various tomato growing localities of Punjab and also the microbial control of H. armigera
The major tomato growing fields of Punjab will be surveyed and samples will be taken from the tomato fields, also various entomopathogenic fungi formulations and other bio-rational approaches will be employed for the eco-friendly management of this insect pest
The results from the first year data clearly indicated the low level of infestation in the localities of northern Punjab
The maximum larval population of H. armigera was observed in the district Bahawalpur with maximum fruit infestation while the lowest for both the cases was in Rawalpindi. The correlation matrix between temperature, relative humidity and larval population revealed that the temperature was positively and relative humidity was negatively correlated with the H. armigera larval population
The project is in progress
