RRdi DIVISIONS

Entomology Division

The main aim of the Entomology Division is to develop environmentally friendly economically viable pest management technologies for insect pests, mites and plant parasitic nematodes in rice. Inaddition, the Division is responsible to conduct research on newly emerging pests, pest out breaks,farmer surveys related to pest management, pest surveillance, pest bio types and insecticide resistance management. Sporadic outbreaks of some rice pests such as white-backed plant hopper (Sogatella furcifera), ear cutting caterpillar (Mythimna separata), cut-worm (Spodoptera spp) and frequent outbreak of brown plant hopper (Nilaparvata lugens) have been reported in the recent past from major rice growing areas of the country. It indicates the effect of global climatic changes on pest aggravation demanding concerted attention from research and development for concerted solutions. Therefore, the researchers in the Division is paying more attention on development activities such as inspection of field problems, conduct awareness programs for farmers and other interesting groups on pest issues and remedial measures to manage.

Services

  • Farmers’field problem identification through field inspection
  • Recommendation of appropriate technologies to manage the pest incidence.
  • Demonstration of pest management practices in farmers field
  • Provision of technical information to extension officers, farmers and other stakeholders through training programs, radio programs, leaflets etc.
  • Training and supervision of students in different categories who are doing their in-plant
  • trainings in the Entomology Division
  • Collaborate the revision of insecticide recommendation book
  • Participation to different meetings such as PTWG meeting and share the subject knowledge with the participants.
  • Re-evaluation of recomended insecticide and provid the efficacy reports to proceed with their re-registration.

Technologies

  • Integrated pest management package for cutworms, ear cutting caterpillars and other defoliators in rice crop
  • Induced resistance technique for rice thrips ; Stenchaetothrips biformis
  • Identification of resistant and moderately resistant rice varieties for BPH and RGM
  • Preparation of 9 pest management decision guides for major pests of rice , maize,onion and chilli in collaboration with CABI
  • Mobile based Information System for Managing Pests and Diseases of Paddy in Sri Lanka (Collaborated with the project)

Research & Publications

BPH and RGM are considered as the most devastating pests of rice in the country. Therefore, it is very important to strengthen the rice varietal improvement through finding new sources for pest resistance and to help minimize biotype development. With that objective Entomology Division continued its efforts to screen all the rice breeding lines under greenhouse condition for BPH and field screening for RGM…
