Screening Sapota Varieties Against Bud Borer (Anarsia achrasella Bradley) under South Gujarat Condition

Abstract

Evaluation of 23 sapota varieties/hybrids was carried out against bud borer, Anarsia achrasella Bradley at Fruit Research Station, NAU, Gandevi, Gujarat for three consecutive years. The pooled results of varietal performance showed that bud borer infestation was low in Mohangoottee, PKM-1, Zumakhiya, Chala collection-1, PKM-2 and Pilipatti with 4.67, 4.81, 4.89, 4.97, 5.06 and 5.08% bud and flower damage, respectively and were 38- 44% superior to susceptible variety Kalipatti.While the higher bud and flower damage in CO-1 (3.88%), Paria Collection (8.84%) and Kalipalli (8.25%) and former both varieties had 7% more susceptibility than later one. PKM-5, CO-1 and PKM-4 exhibited peak damage in April. Kalipatti, Paria collection, CO-2 and DHS-1 suffered, peak damage in May that coincided with focal phase of summer flowering.
