Abstract

Chilli is one of the most important vegetable crop that belongs to the Solanaceae family. It is one of the major crop that has suffered a lot due to insect and pest incidence. Chilli thrips are the exotic invasive pests of utmost importance. This pest damages all plant parts, feeds on young leaves, buds and fruits, destroying it physically and acts as a vector for viral diseases. The present study was conducted to check the pattern of various weather parameters during the crop growing season and its influence on the incidence of thrips population on the crop. It was recorded that the population of thrips started rising from 35th SMW and reached to a maximum at 45th SMW then started declining. It was also recorded that the thrips population was non-significant and positively correlated with maximum and minimum temperature, and the value recorded was 0.11 and 0.211, respectively. However, for weather parameters like rainfall relative humidity at morning time, negative and non-significant

Conclusion

It was observed that the peak population of thrips was recorded at 45th SMW. The population of S. Dorsalis were negatively and non-significantly correlated with precipitation and relative humidity at morning hours. But there population were positively and non-significantly correlated with maximum and minimum temperature. However thrips population shows negative and significant correlation with evening relative humidity. Further studies required to develop a model of abiotic factors and thrips population.
