Effect of Natural Habitat on Diversity of Hemipteran Predator in Oil Palm Plantation

Abstract

Effect of Natural Habitat on Diversity of Hemipteran Predator in Oil Palm Plantation. Utillization of natural enemies in controlling oil palm pests still encounters obstacles, in particular, how natural enemies can survive and establish in oil palm plantations. The existence of natural habitats around oil palm plantations can allegedly support the occurence of natural enemies. The objective of this study was to investigate the effect of the presence of natural habitats on diversity of hemipteran predators in oil palm plantations. Field research was conducted in oil palm plantations located in Pangkalan Bun, Central Kalimantan. The plots were oil palm plantations with different distances from natural habitat i.e. near (less than 200 m), medium (about 2 km) and far (about 5 km). Each plot was selected six trees for fogging using insecticide with active ingredient lamda cyhalothrin. Based on research result, diversity of hemipteran predator in oil palm plantion was found 19 species belong to 2 families. The most dominant hemipteran predator was Sycanus sp., Eocanthecona sp. and Reduviidae sp5. The distance of oil palm plantation from natural habitat did not affect species richness, abundance and composition as well as recolonization of hemipteran predator in oil palm plantation. Abundance of hemipteran predator tend to decrease in different observation time, except Sycanus sp. Sycanus sp was likely has ability to rapidly recolonized and their occurrence were influenced by flowering vegetation in oil palm plantation.

“…The parasitoids usage as natural enemies must consider the fluctuations and seasonal patterns of the main agent and its competitors, so the biological control process is effective (Frago et al, 2012). Also, habitat engineering needed so that parasitoids can survive and develop naturally, especially related to the food needs of these natural enemies (Rizali et al, 2018).…”

Keanekaragaman Serangga Predator Pada Perkebunan Kelapa Sawit Di Lahan Bukaan Baru Dan Bukaan Lama

“…Keanekaragaman serangga pada suatu habitat berbeda, karena faktor tanaman, keadaan iklim, dan keadaan habitat di sekitarnya (Rizali et al 2018). Keberadaan hutan sebagai habitat alami menyediakan jumlah serangga karnivora lebih banyak dan keanekaragaman serangga lebih tinggi dan kompleks dibandingkan dengan agroekosistem (Lubis et al 2021).…”

Population status of the oriental pied hornbill in oil palm landscapes with a conserved natural habitat in Runtu Village, West Kotawaringin, Central Kalimantan

“…This particularly true since this species dependent their survival on the present of big trees for nest and nurture their offspring [13] [15]. Patches of natural habitats are still be found in human-dominated landscapes such as oil palm plantations [18] [19]. Therefore, conservation efforts for this species should not only be focused on the great extent of natural habitats such as national parks and other protected areas but conservation should also be paid on natural patches in the human-dominated landscapes, including oil palm plantations.…”
