1 This insect pest occurs in all groundnut growing areas in India. The adult is dark brown bug (Fig.). In the field, the females lay their eggs in the soil or on groundnut haulms during harvest. In storage eggs are laid loosely among the groundnuts or on sacks. All stages of this insect attack the kernels (seeds). Virtual Academy for the Semi Arid Tropics Lesson 2: Pod Sucking Bug Course on Insect Pests of Groundnut Module VI: Storage Pests

2 Virtual Academy for the Semi Arid Tropics Lesson 2: Pod Sucking Bug Course on Insect Pests of Groundnut Module VI: Storage Pests Damage This bug feeds on pods left in the field to dry, or on stored pods. In storage this bug feed on seeds, perforating the pod with their rostrum. This causes the seeds to shrivel and increases the free fatty acid content of the oil, producing a rancid flavor. Thus, the quality of groundnuts, and also the keeping quality of groundnuts are affected.

3 Virtual Academy for the Semi Arid Tropics Lesson 2: Pod Sucking Bug Course on Insect Pests of Groundnut Module VI: Storage Pests Management Maintenance of optimum moisture content (not >5%) is always critical in preventing the development of storage pests. For protection against this storage pest, groundnuts should be stored unshelled.

4 Virtual Academy for the Semi Arid Tropics Lesson 2: Pod Sucking Bug Course on Insect Pests of Groundnut Module VI: Storage Pests Management If groundnuts are stored as seed, care should be taken to avoid breakage. Broken seeds should not be stored for long periods. Dusting with an inert substance such as attapulgite-based clay dust (ABCD) can help to minimize storage insect problems.

5 Virtual Academy for the Semi Arid Tropics Lesson 2: Pod Sucking Bug Course on Insect Pests of Groundnut Module VI: Storage Pests Management Fumigation of pods with Aluminum phosphide (Celphos) at 3 g tablets per bag of groundnut (40 kg) and covering the sacks with polythene sheet for 5 days can effectively control bruchids without affecting the seed viability. Fumigation should be done only in well aerated places outside the residential areas or in seed godowns only, under the supervision of plant protection specialist.

6 With this, the Lesson on Pod Sucking Bug, and Module VI on storage pests in Groundnut concludes. To review this Course, please select any Module from the Course contents. Virtual Academy for the Semi Arid Tropics Course on Insect Pests of Groundnut Module VI: Storage Pests
