Impact of climate change on insect pests cause for concern- Gairola
The director general of Indian Council of Forestry Research and Education (ICFRE) SC Gairola expressed his concern on the effect of climate change on insect pest incidences in nurseries, plantations and natural forests. He was speaking at the inauguration of a one-week compulsory training course on insect pest management inf orest nurseries, plantation and natural forests for forest officers at the Forest Research Institute (FRI).
Addressing the gathering he said that the climate changes may also trigger organisms to find new and more vulnerable hosts. There will be more rapid development and growth rates or high fecundity and more number of generations per seasons. Many insect species will extend their ranges towards higher altitude. He also emphasised that the knowledge on insect – pests is very important under changing climatic conditions as the entomological problems are critical in disturbing the productivity of forests because during every stage in the tree growth from the seeds to the finished products, insect problems are persistently encountered.
The FRI director AS Rawat introduced the participants to the impact of pests and diseases in plantations in quantitative terms and highlighted their significance considering the economic loss caused by them. In recent years there have been several epidemics of insect and diseases causing economic damage to forest trees in India.
