Abstract

The fruit of sineguelas (Spanish plum) is considered as source of income in Batangas. Some farmers and households were quite alarmed of the pest infesting their plum trees. A field validation was conducted by the Bureau of Plant Industry, Crop Pest Management Division on August 17, 2016 in Barangay Bulsa and in other adjacent farms in San Juan, Batangas. An insect belonging to Order Coleoptera, family Chrysomelidae and also known as leaf-eating beetle or spotted beetle infested their plum trees. Both larvae and adults feed on and skeletonize the leaves. Initially, it was identified as Podontia sp. Moreover, initial rearing was conducted in the laboratory. The eggs were laid in clusters of 20-40 and incubation period was 7-8 days while larval period was 11-18 days and pupal period, 10-29 days. Life cycle ranged from 30-60 days.
