Spotted pod borer : Maruca testulalis (Pyraustidae: Lepidoptera)
Damaging systems:
- The larva webs together the leaves, buds and pods and feeds inside these webs.
- The caterpillar also bores into pods and eat up the ripening seeds.
- A crown mass of excrement is seen at the entrance into the larval burrow
Management:
Cultural Control
- Timely sowing should be done preferably up to first quarter of July.
- Excess application of nitrogen should be avoided.
- Water logging should be prevented.
Biological Control
- Conserve ants and praying mantids as these are good predators of egg and larva of the pest
Chemical Control
- Apply chemical insecticide only if the pest population crosses ETL.
- Spraying of 0.07% endosulfan ( 2ml of 35 EC/lit. of water) or 0.04% monocrotophos ( 1 ml of 36 Sl /litre of water) or chlorpyriphos 20 EC @ 3.5 ml/lit. of water at 600-1000 lit. of spray material per ha. with hand sprayer.
