Abstract

Oryctes rhinoceros or Rhino beetle ( Coleoptera; Scarabidae) is a major pest in oil palm plantations. This pest is very harmful, especially in replanting areas, and young plants cause up to 25 per cent of palm oil-related deaths. This study aims to evaluate the effectiveness of integrated pest management in suppressing the population and development of O. rhinoceros. The research was conducted at the Oil Palm Plantation, PT. Sumber Indah Perkasa, Penawartama, Tulangbawang Regency, Lampung Provincial for one year. The analysis used is a descriptive analysis involving the collection of data from a variety of control techniques. The results showed that the pest control techniques of O. rhinoceros lightrap, ferotrap, holetrap, nets, larval quotes and chemistry could suppress or decrease pest populations. The control with light traps is very efficient because it obtained the number of captures of imago beetles up to 246,224 in 1 year. The integrated pest control of O. rhinoceros successfully reduced the attack of beetles until it did not reach the economic threshold. It is hoped that implementing integrated O. rhinoceros pest control can be a reference for plantations

Abstract

Horn beetles (Oryctes rhinoceros) are among the pests in oil palm plantations. This study aims to find out the usefulness of Metarhizium anisopliae with a combination of various ways of application and dosage to suppress the development of Oryctes rhinoceros larvae in unproditioned plants (TM) in oil palm plantations. The experiment was conducted using a complete randomized design of two factors, namely eight treatments and three repeats, namely, the application of mushrooms M. anisopliae formulation of rice flour with a dose of 15 g / m2, 20 g / m2, 30 g / m2 and application of mushroom M. anisopliae dissolved in 1L water at doses of 15 g, 20 g, 25 g and 30 g. Observational data that the number of larvae infected and larval mortality were further analyzed by One Way Anova and further tested duncan with a real level of 5%. The observations showed differences in the number of infected larvae and the mortality of the larvae. The highest number of infected larvae and larval mortality occur in the treatment of M. anisopliae fungal application.

Abstract

The use of traps is one of the environmentally friendly pest controls. Insects have a preference for the colour of objects. The research aims to determine trap colours' effectiveness in catching rice plant pests. The research was conducted from  June to July 2021 in Depok, Sleman Regency, Yogyakarta Special Region. The study used a descriptive observational method on an 8-week-old rice planting area. The colour traps used are white, red, green, yellow, and blue.  The experiment used a completely randomized design with five replications. The results showed that the yellow trap produced the most insect catches, namely 545 insects, and the white colour produced the lowest catch of 74 heads.  Pests that are heavily trapped in a row from the most to the least are Hydrelia sp, Leptocorisa oratorius,  Nephotettix virescens,  Pareaucosmetus sp, and Nilaparvata lugens. The most trapped is Hydrellia sp, as much as  78% of the total trapped insect pests. Effective trap installation time in the morning.

Abstract

Some types of plants can serve as plant-based insecticides. Ginger (Zingiber officinale) and Turmeric (Curcuma domestica) are ingredients that are often used as pesticides on various plant pests. Spodoptera litura itself is a pest that is quite annoying in various plants. The study aimed to examine ginger (Zingiber officinale) and turmeric (Curcuma domestica) extracts as insecticides to control armyworms (Spodoptera litura). The research was carried out in Pelemsari Village, Prenggan, Kotagede, Yogyakarta from May to June 2022. The study used a Complete Random Design (RAL) with 2 factors. The first factor is the type of extract, namely ginger and turmeric. The second factor is the concentration of the extract which consists of 3 levels, namely 20%, 40%, 60% and control, each treatment is repeated 3 times. To find out the real difference between the data treatments, the observation results were analyzed with Duncan's Multiple Range Test (DMRT) at the real level of 5%. Ginger and turmeric extracts at a concentration of 20% have been able to control S. litura larvae. Ginger extract is more effective compared to turmeric extract based on the mortality test, efficacy, death rate, and feed spoilage rate of S. litura larvae. The research is still in the experimental stage in the laboratory and needs to be tested in the field to get an effective dose for armyworms.

Abstract

The rhinoceros beetle (Oryctes rhinoceros) is a fairly important pest in oil palm plants, especially in young or unproductive plants. The purpose of this study is to examine the use of pheromones and lamps as horn beetle traps. The research was carried out in a community plantation in Sungai Lala, Kelawat District, Indragiri Hulu, Riau. The research was carried out for 1 month, with tools in the form of lamp traps and pheromones, as well as a combination of both.  The results showed that the combination of pheromones with trap lights provided the most catch compared to single treatment. There was no difference in the catch of male and female beetles in all treatments. It is hoped that the results of this research can be used to control rhino beetles in a simple way in community plantations.

Abstract

This study aims to determine the level of attack and distribution of Argentine flies (Cecidochares connexa) as biological control agents against Siamese weed (Chromolaena odorata) in Gunungkidul Regency. The method used was a field survey in June–July 2024, with direct observation and sampling of host plants in four cardinal directions from the starting point of release (Wanagama I Forest). The parameters observed included the percentage of attacks, the number of puru, and puru holes per plant. The results showed that the highest attacks occurred in the Western region (72%), followed by the South (69%), the North (68%), and the East (49%). The average attack across the region reached 65%.  C. connexa has become widespread and established in the Gunungkidul area.

Abstract

Cashew nut skin is considered as waste, whereas cashew nutshell extract, or called CNSL (Cashew Nut Shell Liquid), has the potential as a botanical insecticide that can control insect pests. Helopeltis sp is a pest that often attacks cacao plants. The study aims to determine the effectiveness of cashew nutshell extract as a botanical insecticide to control  Helopeltis sp. in cacao plants. The study used a randomized block design (RBD) with seven treatments and three replications. Testing CNSL on adult (imago) and pre-adult (nymph) insects. CNSL concentrations used are 0%, 3.125%, 6.25%, 12.5%, 25%, 50% and 100%. The results showed that cashew nutshell extract has strong toxicity. A concentration of 3.125% can kill 100% of the imago Helopeltis sp. (72 hours after application) for the nymph Helopeltis sp. (48 hours after application). LC50 values 24 hours after application for imago and nymph were 4.63% and 0.94%, and LC99 for imago and nymph was 42.62% and 23.89%.  Furthermore,  cashew nut extract can be used as a botanical insecticide to control other plant pests.

Abstract

The extensive use of synthetic insecticides has led to environmental contamination, pest resistance, and adverse effects on non-target organisms. Botanical insecticides provide a safer alternative for sustainable pest management. This study evaluated the insecticidal activity of betel leaf (Piper betle L.) and Lantana camara leaf extracts against armyworm (Spodoptera litura).  A laboratory bioassay was conducted using three extract concentrations (30%, 40%, and 50%) arranged in a completely randomized design. Larval mortality was recorded daily for seven days after application and analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Both botanical extracts significantly increased larval mortality over time. Mortality began to rise on the second day and increased sharply on the third and fourth days after application. By the fifth day, all extract treatments resulted in nearly 100% mortality, while no mortality occurred in the control. Cumulative mortality patterns indicated that Lantana camara induced a faster initial lethal effect, whereas Piper betle showed a slightly delayed but equally effective response. No significant differences were observed among concentrations, indicating that a 30% concentration was sufficient for effective control. These results highlight the potential of betel leaf and Lantana camara extracts as effective botanical insecticides for armyworm management.
