Elakkiya S, Suganthy M, Bhuvaneswari K, Rajasree V, Renugadevi J and Senthamizh Selvi B Abstract Coriandrum sativum is an important green leafy vegetable as well as seed spice crop. Among the various insect pests infesting coriander, the coriander aphid, Hyadaphis coriandri is a regular and major pest of coriander and responsible for reduction in crop yield. Development of eco-friendly pest management practices is essential in the production of high quality and pesticide residue free produces. Field experiment was conducted at Pappampatti, Coimbatore district, Tamil Nadu from January 2021 to April 2021 to develop IPM module for the management of aphids, Hyadaphis coriandri infesting coriander. Results of the field experiment revealed that among the treatments, IPM module (T5) comprising of designer seed treatment [Polymer (3g) - thiamethoxam 5 FS (5g) - azospirillum (120g) - Trichoderma viride 4 g per kg of seed] - border cropping with cowpea - erecting yellow sticky traps at 12/ha - need based application of spinosad 45 SC @ 75 ml per acre recorded the lowest mean population of aphids (5.72 aphids per three umbels plant -1 ) followed by another IPM module with azadirachtin 10,000 ppm (T4) (7.07 aphids per three umbels plant -1 ) and farmer’s practice (7.77 aphids per three umbels plant -1 ). The IPM modules (T4 and T5) were designed in such a way that they are safe to the natural enemies, which recorded the highest population of coccinellids viz., 1.59 and 1.57 coccinellids per plant, respectively. Maximum harvestable seed yield of 960 kg/ha was recorded in T5, the IPM module with spinosad 45 SC followed by farmer’s practice (857 kg/ha). Hence, the IPM module with spinosad 45 SC (T5) is adjudged as the best treatment for the management of coriander aphids, H. coriandri.

Introduction Coriander (Coriandrum sativum L.), belongs to the family Apiaceae, is an important seed spice crop grown mainly in Madhya Pradesh, Rajasthan, Andhra Pradesh and other states of India. It is commonly called as dhania and cultivated for both green leafy vegetables and seed purposes. Among all the seed spices, coriander occupies first place in India in terms of area, production and productivity. Coriander is also grown as intercrop in various crops since it attracts large number of predators, parasitoids and pollinators due to the presence of huge quantity of nectar and volatile oil emitted from the plant. A number of insect pests viz., thrips, Thrips tabaci, jassids, Empoasca kerri, aphids, Myzus persicae [1] , Hyadaphis coriandri [2] , Aphis gossypii, Aphis craccivora, pod borer, Heliothis armigera, whitefly, Bemisia tabaci, seed wasp, Systole albipennis [3] , bugs, termites and few lepidopteran caterpillar inflict damage to this crop [4] . Among the insect pests, aphids are the most important pests of coriander causing maximum crop losses at field conditions. Aphids are also responsible for loss of seed health and quality. Initial population establishment starts during vegetative stage, whereas, the peak population reaches during flowering and fruiting stages of crop [5] . Thus, aphids cause more damage to the harvestable produce of the crop resulting in yield loss up to 50 per cent and reduce the quality of seeds [6] . In the present day agriculture, farmers are solely relying upon variety of insecticides for pest management and such indiscriminate use of pesticides results in accumulation of pesticides on the harvestable produces in the form of residues, development of resistance to insecticides, resurgence of minor pests and mortality of non-target organisms such as natural enemies and pollinators particularly honeybees. Pesticide residue in seed spice is becoming a major concern particularly in coriander due to which the country faces a huge loss in national economy [7] . Considering the significance of this pest, the present study was undertaken to develop Integrated Pest Management (IPM) module for the management of aphids, H. coriandri infesting coriander.
