Abstract:
Jute is an economically important fibber crop of India which is known for its agriculture based economy. Though India holds first position in raw jute cultivation but never achieved its goal of per capita production to fulfill national and international market demand. Destructive action of Anomis sabulifera is one major cause of jute production loss though farmers are using increasing dose of chemical pesticides. Present study focused on to understand life history of the pest to generate pest calendar which will impart effective control measures against the pest. Investigation showed that life cycle of a. sabulifeara varies from 28-34 days in field while it was quite regular in laboratory conditions. Four generation of the pest was observed during study period with different degree of incidence. 3rd generation pest population was noticed as most devastating to host crop with highest infestation (1.65 larvae/leaf). Pest dynamics was significantly influenced by the agro-climatic conditions (99.10%). Based on those data pest calendar was provided which could offer a clearly commanding informative outline for pest control measure.
