Groundnut (Arachis hypogeae L., Fabaceae) is the major oilseed crop, which is grown on all over the world. Groundnut grows well in Open Access tropical and sub tropical regions of the world especially India, Pakistan, Srilanka, Myanmar and South Africa. It is a valuable Corresponding Author cash crop for millions of small scale farmers. In India groundnut A. Yogapriya is a principal oilseed crop which has high nutritional value. e-mail: [email protected] Seeds are rich source of edible cooking oil (43-55%), protein (25-28%), vitamins like E, K and B. Byproduct groundnut cake was obtained after extraction of oil from seed which has rich Keywords source of protein which is used as animal feed. Groundnut is grown in eleven states of India on an area of 5.98 million Aproaerema modicella, Groundnut, Integrated pest hectare with a production of 4.98 million tonnes of pod per management, Rainfed crop annum with an average productivity of 860 kg/ha. The major groundnut growing areas are Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka and Maharashtra accounting more than 80 percent of the total area and production (Krishna Naiket al., 2020). The production was quite so high but in the aspect of farmers field production was quite low because of its incidence of pests and diseases. The groundnut leaf miner Aproaerema modicella, causes more than 50% yield loss to the crop particularly in rainfed condition of Tamil Nadu (Pazhanisamy and Hariprasad, 2014). About 80% of the groundnut area in the country is rain dependent and the productivity is very low Article History compared to irrigated groundnut. A. modicella infestations are Received in 21st June 2021 most serious when they damage the growing points of young Received in revised form 24th June 2021 plants, thereby reducing growth and pod yield of the plant. Accepted in final form 25th June 2021 Host range: It causes damage on Groundnut, Soybean and Red gram crops. E-mail: [email protected]

Bionomics PM at ground level to monitor pest population. • Practice mulching with rice straw which may reduce the leaf Common name: Leaf miner miner incidence. Scientific name: Aproaerema modicella • Maintain the field free from weeds and avoid the water stress Family: in irrigated crop to reduce the pest population. Order: • Practice crop rotation with crops like maize, cotton and • Egg: Eggs of the leaf miner are shiny white in colour and are sorghum to reduce the leaf miner incidence and give better laid singly on lower side of the leaflets. yield. • Larva: Larva are light green or brown in colour with dark Biological Control head and prothorax. onserve the natural enemies like spider, praying • Pupa: Pupae are reddish brown in colour and pupate in white mantids, ants, ladybird beetlesetc. Intercropping with silken cocoon within the webbed leaflets. Cpearl-millet will increase the Goniozus spp. parasitoid population which parasitizes the leaf miner pest population. • Adult: Adult leaf miner is a tiny , measures about 6mm in long with 10 mm wingspan.

Symptom of Damage Application of following insecticides reduces the leaf roundnut leaf miner (GLM) causes damage on miner infestation viz., Deltamethrin 02.80% EC or Lambda- leguminous host plants which is a serious pest of cyhalothrin 05.00% EC or Quinalphos 25.00% EC.

Initially newly hatched green from September to November to the rainfed crop caterpillar made short blisters like mines into leaflets and and during March and April to the irrigated crop. feed on the mesophyll layer of leaf tissues which results in G Management of leaf miner incidence increases the yield of a brownish dried up patches.
