Abstract

Cocoa pod borer (Conopomorpha cramerella L.) is a major pest of cocoa, including in Southeast Sulawesi and is able to reduce yields up to 90%, especially in the dry season. So far, farmers control these pests through the application of chemicals with high doses so that it has a negative impact on the environment. The aim of this research was to obtain a package of environmentally friendly C. cramerella pest control technology which was carried out at the center of Watarema Village, Lambuya District, Konawe Regency in 2019. The study was arranged using a randomized block design (RCBD) with 6 treatments, namely: (a). Beauveria bassiana, (b). Citronellal eleostreric myuric acid lauric acid, (c). Trichoderma asperellum, (d). A combination of garlic extract and clove oil, (e). Lighting + ultrasonic sound waves, and (f). lambda cyhalothrin thiametoxam as a control. All treatments were repeated 5 times on Sulawesi 1 cocoa clones, aged 10 years. Observation data were analyzed using analysis of variance and continued with the mean value test using Duncan’s multiple range at the 0.05 level. The results of preliminary observations indicate the percentage of pest attacks at the study site ranged from 40-90%. The results showed that the lighting treatment at night accompanied by the use of ultrasonic sound produced the lowest percentage and intensity of attacks, respectively 7.69% and 7.85% and were significantly different from controls, although not significantly different from other treatments. Decreasing the percentage and intensity of C. cramerella pests can improve the health of cocoa beans and fruit. This is able to increase the number of fruits and seeds, dry seed weight and weight per 100 seeds, seed yield, and cocoa productivity of 730.19-805.35 kg / ha and reduce cocoa yield loss of 432.87-511.55 kg / ha.
