PENGUJIAN BEBERAPA PERANGKAP HAMA TANAMAN KELAPA SAWIT (Elaeis guineensis Jacq.) Oryctes rhinoceros Linn.

Abstract

The decline in the production of oil palm yields in the village of Tomuan Holbung,
the sub-district of Bandar Pasir Mandoge, was identified as a result of the very high spread of
pests. Pests that are often found one of them is a type of rhino beetle pest (Oryctes rhinoceros
Linn.). The purpose of this study is to find out what traps are more effective in controlling
Oryctes rhinoceros Linn pests and also to get a comparison of the interests of Oryctes
rhinoceros Linn based on sex to some trap treatments. The use of traps to be tested on
Oryctes rhinoceros Linn are: 1) traps in yellow color (W0), 2) traps with pheromones (W1),
3) traps in yellow color and pheromones (W2). The parameters observed in this study were
the population of Oryctes rhinoceros Linn who were attracted to the traps observed 2 days
after laying the traps (2 HSA) for 4 weeks and the population of Oryctes rhinoceros Linn
caught by male or female sex. The results showed that the highest number of catches of
Oryctes rhinoceros Linn was found in the treatment of yellow and pheromone (W2) traps,
namely 25 insects with an average population of imago trapped at 6.25 insects / month (± 6
insects / month ). Then followed successively by trapping treatment with pheromones (W1)
as many as 19 insects with an average trapped imago population of 4.75 insects / month (± 5
insects / month) and trap treatment with yellow (W0) as many as 6 insects with an average
population of imago trapped by 1.5 insects / month (± 2 insects / month). While the catches of
male and female Oryctes rhinoceros Linn imago based on the sex of male and female
obtained results that the female Imago Oryctes rhinoceros Linn was more numerous than the
male Imago Oryctes rhinoceros Linn trapped because female imago were more interested and
recognized molecules from synthetic aggregation pheromones (Ethyl 4-methyloctanoate).
