Abstract

One of the major pests that attack nutmeg plants is Batocera Hercules, which can reduce yield both in quantity and quality. An investigation with an aim to determine the level of Batocea hercules attack on three types of nutmeg trees was conducted in Wakate Subdistrict, Watubela Island, Maluku. The study used a survey method by direct observations in the farmers' nutmeg cultivation areas in District Wakate, Watubela Island. The results showed that the attack level by Batocera hercules the cultivation area of the study was 19.19%, with the number of bore holes 2.08. The major attacks occurred on the nutmeg types of Banda, Onin, and cross, at 23.01%, 30.28% and 4.28% intensities, respectively.  The intensity of attacks were affected by nutmeg cultural techniques and climatic factors.

Abstract

Plant pests Spodoptera litura is one of the major insect pests that often lowers the cabbage yield. Various control techniques of this pest have been developed, such as the use of botanical pesticides. This study aimed to determine the role of aromatic plants in reducing S. litura population growth and plant damage intensity on cabbage. Experiments used intercropping combinations of cabbage-local basil (‘kemangi’), cabbage-tomato, cabbage-scallion and without aromatic plants as a control. The experimental was arranged in a Randomized Block Design. Parameters measured were larval population, damage intensity and fresh weight of cabbage crops. The results showed that all three cabbage intercropping with the aromatic plants were able to suppress population of S. litura and the resulted damage intensity of cabbage. The treatment of cabbage intercropping with local basil could reduce larval populations of S. litura (to 0.84 larvae) or only 8 larvae per 10 plants and with the lowest crop damage intensity (3.32%) and highest crop weight (486.6 g) per plant.
