dc.description.abstract	Satu kajian untuk pewujudan Dolichoderus thoracicus (semut hitam) dan kutu putih (Cataenococcus hispidus) sebagai agen kawalan biologi untuk mengawal Pengorek Buah Koko (PBK) (Canopomorpha cramerella) dilakukan di ladang koko Bah Lias LONSUM di Sumatera Utara. Canopomorpha cramerella dewasa betina lebih suka bertelur di buah koko peringkat 4 (yang berumur 14-16 minggu, panjang buah 15 – 20 cm). A study on the establishment of Dolichoderus thoracicus (black ant) and Cataenococcus hispidus (mealybug) to be used as biological agents for Conopomorpha cramerella, cocoa pod borer (CPB) was carried out in LONSUM cocoa estates in Bah Lias, North Sumatera. Conopomorpha cramerella moths prefer to lay their eggs on cocoa pods stage 4 (age 13 – 16 weeks old; 15 to 20 cm length).	en_US
