Patent / Technologies / Methodologies / System etc. (Upto Five) :

  1. New Pest Species of Cardamom: A new species, Conogethes sahyadriensis (Lepidoptera: Crambidae), feeding by boring stem and capsules on cardamom, is described from India. The new species was discovered by diagnostic morphology as well as by molecular phylogenetic data. Maximum yield loss of up to 54% capsules and 30% dead heart is reported from new stem and capsule borer at present. (Team lead)
  1. First report of New Invasive Insect Pest from India and Rapid Action Plan for management Devastating South American tomato pinworm, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) also known as the tomato leaf miner is identified as the most destructive invasive pests which damage the tomato yield to the extent of 50-80%. This pest is being reported for the first time in India (Team lead)
  1. Plusiinae of India website: Taxonomic database of subfamily Plusiinae which is one of the agriculturally important moths (Lepidoptera) group. This website provides Plusiinae species checklist, terminologies and species pages (comprising of 30 species and more than 122 diagnostic/identification images) for Indian species of Plusiinae. http://npc.iari.res.in/plusiinae/index.php (Developer)
  1. IARI-National Pusa Collection Website: National Pusa Collection (NPC) is an integral section of the Division of Entomology, ICAR-Indian Agricultural Research Institute, New Delhi. NPC holds over five lakh specimens and 22845 species serve as a national repository for insect pests of crops. http://npc.iari.res.in/ (Developer)
  1. Pusa Preet: A New Capsicum variety (Associate)It is developed for low-cost net house/ polyhouse/ protected structure. It is the first capsicum variety from public sector for cultivation under protected structures for North Indian plains. The fruit weight is about 85-95 g with approximate average fruit yield 2.15-2.75 kg/plant with yield potential of 5-6 t/1000 m2.
