Abstract

Pollination in oil palm is generally carried out by insects. The beetle Elaeidobius kamerunicus is one of the effective pollinating insects for oil palm. This beetle breeds well on male flowers, this beetle can also reach female flowers located in the inner bunch, so this condition causes more perfect pollination. This study aims to determine the population of oil palm pollinating insects E. kamerunicus at several ages of oil palm plants which will be associated with environmental factors and ways of oil palm cultivation, both application of pesticides and fertilizers in Rasau Jaya District, Kubu Raya Regency. Insect sampling in this study used a purposive sampling method (determined sample), which used 3 plant blocks with different age groups of 4, 6, and 9 years respectively. The method used is the observation method, namely observing the population of oil palm pollinating insects directly on oil palm flowers. Observations were made on the population of E. kamerunicus by counting the number of E. kamerunicus visiting blooming oil palm flowers obtained from yellow sticky traps with a size of 20x30 cm placed near oil palm flowers. The results of the study concluded that the older the age of the oil palm plant, the greater the number of spikelets and the population of E. kamerunicus insects increased.
油棕的授粉一般是由昆虫来完成的。金龟甲是油棕有效的传粉昆虫之一。这种甲虫在雄花上繁殖得很好,这种甲虫也可以到达位于束内的雌花,所以这种情况会导致更完美的授粉。本研究旨在确定库布拉亚县Rasau Jaya地区油棕传粉昆虫E. kamerunicus在油棕植株不同年龄的种群数量,这与环境因素、油棕种植方式以及农药和化肥的施用有关。本研究昆虫取样采用目的取样法(确定样本),选取3个植物块,分别为4岁、6岁和9岁不同年龄组。所采用的方法是观察法,即直接在油棕花上观察油棕传粉昆虫的种群。在油棕花附近放置20 × 30 cm大小的黄色粘捕器,对油棕花采蝇数量进行了观察。研究结果表明,油棕树龄越老,其颖花数量越多,油棕螟种群数量增加。
