Status of Pest, Oryctes rhinoceros and Its Natural Enemies in the Independent Smallholder Treated with Different Insecticides. Agriculture, Forestry and Fisheries. Vol. 8, No. 4, 2019, pp. 89-94. doi: 10.11648/j.aff.20190804.12 Received: July 28, 2019; Accepted: August 19, 2019; Published: September 17, 2019 Abstract: A field study was carried out at Tangkak, Malaysia regarding Oryctes rhinoceros’s infestation and its natural enemies after being treated with selected pesticides from January until October 2017. The objective of this study to examine the effect of different insecticides usages with the presences of Oryctes rhinoceros including unteated area and population of Oryctes’s natural enemy in the oil palm areas of smallholders. Three treatments with four replicates were applied in the selected oil palm area, namely Cypermethrin, Carbofuran and Untreated (without chemical). Twelve smallholders with three different insecticides used were chosen randomly and twelve samples were taken as replicates. Effects of the beetles’ population over the chemical’s treatments were analyzed using analysis of variance (ANOVA) (SPSS - version 23). The results dramatically revealed that the least presence of Oryctes rhinoceros was detected at Untreated area with total mean of 0.21, followed by Carbofuran with total mean of 2.63 and Cypermethrin with 3.12. The result of this study indicated that Oryctes rhinoceros in Tangkak, Johor has developed resistance to the insecticides used by the growers due to high frequency of similar type of chemical. These insecticides had no significant effect towards the natural enemy found in oil palm area in Tangkak which is Platymeris laevicollis. These natural enemies also showed no relationship directly with the presences of Oryctes rhinoceros due to low diversity of plant species or particularly lack of shelter.

This crop usually being grown in a large scale estate around 3000 to 5000 hectares. It is known to be originated from the West of Africa. Oil palm is usually being planted in area with rainy tropical lowland. In order to produce a high quality of oil palm fruits, it needs to meet specific requirements such as a suitable temperature, deep soil and also suitable moisture throughout the year. In addition, the yield of the oil palm is not only can be affected by the temperature and the soil moisture, it is also affected by the presence of the pest and diseases. Oil palm has a high risk to be infected with one common pest which is Oryctes rhinoceros [1]. Oryctes rhinoceros is commonly known as ‘kumbang badak’ or rhinoceros beetle in Malaysia. Rhinoceros beetle can be reduced using several methods such as chemical, cultural, biological control and others. One of the effective ways is by applying chemical pesticides. Ahmad [2] stated that the application of insecticides towards the palms gives a significant result in term of controlling the beetles’ population and the damage
