The climate in the Cordillera Administrative Region is suitable for growing various semi-temperate vegetables and other fruit-bearing crops. The high attitude of Benguet makes it deal for strawberry production, while the municipality of Itogon and the provinces of Apayao and Abra with a warmer temperature are suited for banana and mango production. Conducted with another parallel study, the assessment and identification of beneficial and pest arthropods of selected fruit crops were done through field survey, collection and identification. The presence and degree of injury inflicted by arthropod pests were also recorded. The banana aphid, Pentalonia nigronervosa Coquerel, a notorious vector of the banana bunchy top virus, remained to be a major pest of banana as it was found prevalent in every banana plantation visited. It is present especially on Lacatan variety. Mango twig borers (Callimetopus sp.) urticae Koch remained to be the major pest on strawberry while the veronicilid slug is an emerging major pests on strawberry while the veronicilid slug is an emerging major pest as it targets the berries and reduces yield. The lady beetle Harmonia sp., was observed preying on Pentalonia aphids. Although the said lady beetle generally preys on any aphid species, in mango, the red weaver ant Oecophylla sp, a generalist predator, was also observed. To summarize, there were a total of 19 arthropods identified and collected on banana plants, 10 on mango plants, and eight on strawberry.
