Abstract
A survey study was undertaken in Sericultural Zones falling in different agroclimate of hill, tarai and plain areas of Uttar Pradesh and Uttaranchal during 1998, 1999 and 2000. A few lepidopterans and coleopteran have been identified as pest on mulberry. The seasonal occurrence of major pests causing damage to mulberry foliage to the economic threshold level have been studied. A calendar of infestation of different pests has been drawn with special reference to the major pests on mulberry.
Pest damage touched the economic threshold level during June and July with increase in pest population. The pest population came down with the pruning of mulberry bushes during the July-August. The pest population increased again with the leaf sprout and reached the high level during the month of September to November. The pest population then decreased in the month of December due to leaf abscission and fall in winter conditions.
