Milestone: Mass production techniques and stable formulations developed (GVRR/OPR) 2009
Activity 6C.5.3: Develop mechanisms to cope with pest outbreaks and management
Milestone: Chickpea pod borer, red hairy caterpillar, groundnut leaf miner, and Spodoptera prediction models
validated (GVRR) 2007
The populations of the aforementioned insect species are being monitored at ICRISAT center using light and
pheromone traps, and field scouting. The efforts to develop population prediction models are in progress, which will
be validated in the near future.

Milestone: Tools for the pest identification and nature of damage for different crops developed (HCS/GVRR) 2008
Insect pests damaging the ICRISAT mandate crops are being diagnosed regularly at the ICRISAT research farms,
and on the farmers fields to recommend appropriate control measures. The database is being updated regularly.

Milestone: Potential kairomones for attracting Helicoverpa adults identified (GVRR/HCS) 2009
The relative attraction of H. armigera females to different host plants and their volatile compounds is being studied
to identify chemical components that play a major role in host plant selection by the insects. The females of H.
armigera prefer to lay eggs on pigeonpea than on cotton, indicating the possibility of using the later as a trap crop
for pest management in cotton.
