Abstract

The objective of this research was to study the influence of herbicides and time of trapping after
application on population of weevil Elaeidobius kamerunicus. This research was conducted at Oil
Palm Plantation Kalianta, Riau and at Laboratory of Indonesian Oil Palm Research Institute
(IOPRI), using method of Factorial Randomized Group Design with 2 factors, the first was
herbicides (without herbicide, methyl metsulfuron 100 gr/ha, paracuat 400 cc/ha, glyfosat
400 cc/ha) and the second factor is time of traps (2 hours after applications, 48 hours after
application and 72 hours after application) with three replications.The results at field showed that
population of weevil E. kamerunicushigher in treatment without herbicide compared to treatment
using herbicide at male flower was 334 adults/spicelet and female flower was 689 adults/bunch.
Treatment 72 hours after applications traping at male flower on population of weevil
E. kamerunicus was 282 adults/spicelet.

Penelitian ini bertujuan untuk mempelajari dampak dari penggunaan herbisida terhadap populasi kumbang Elaedobius kamerunicus. Penelitian ini dilaksanakan di PPKS Marihat kebun Kalianta, Propinsi Riau dan di Laboratorium PPKS Marihat dengan menggunakan metode Rancangan Acak Kelompok faktorial dengan 2 faktor, yaitu faktor 1 adalah jenis herbisida (tanpa herbisida, metil metsulfuron 100 gram/ha, parakuat 400 cc/ha, glifosat 400 cc/ha) dan faktor 2 adalah waktu pemasangan perangkap (2 jam, 48 jam, 72 jam setelah aplikasi) dengan tiga ulangan. Hasil penelitian di lapangan menunjukkan bahwa populasi kumbang E. kamerunicus lebih tinggi pada perlakuan tanpa herbisida dibandingkan dengan perlakuan dengan herbisida yaitu jantan sebesar 334 ekor/spikelet dan pada bunga betina sebesar 689 ekor/tandan. Perlakuan 72 jam setelah aplikasi pemasangan perangkap pada bunga jantan terhadap populasi kumbang E. kamerunicus yaitu sebanyak 282 ekor/spikelet.
