Abstract

A survey was conducted at Sumiorang, Matungao, Lanao del Norte from March 2002 to December, 2003 with two objectives, namely: to collect and identify the insect pests attacking durian in Lanao and to study the life history of the species causing the greatest damage. The insect fauna of durian consisted of species belonging to 17 families and seven orders. They were classified as phytophagous, parasitoids, predators, and neutral species. The three insect orders to which pest species belong were Lepidoptera (moths and butterflies), Coleoptera (beetles) and Homoptera (mealybugs). The seed borer (Mudaria magniplaga) was the major insect pest of durian. The minor pests were the fruit borer Conogethes punctiferalis Guenee, the pinhole borer Platypus sp. And the mealy bug Pseudococcus sp. Beneficial insects included the coccinellid beetles Micraspis sp., ants spiders, earwigs and syrpid flies. A braconid wasp Asobara sp. Was parasitic on fruit fly maggots which secondarily attack damaged durian fruits. The total developmental period of M. magniplaga ranged from 43 to 56 days with an average of 49.24 days. The duration of the different life stages were as follows: incubation period was 10-14 days with an average of 12.00 days, larval period ranged from 23 to 30 days with an average of 25.92 days, pupal stage 10-12 days with an average of 11.33 days. The adult life span ranged from 9 to 12 days with an average of 10.50 days.
