Abstract

Fire caterpillars (Sethotosea asigna, Lepidoptera: Limacodidae) are a major pest of oil palms and cause harvesting losses. Natural enemies such as Sycanus sp. are reported to control fire caterpillars. The biological of Sycanus sp. were observed in the laboratory when fed using the alternative feed, maggot Black Soldier Fly (Hermetia illucens L.). Variables observed were egg, nymph, imago stadia, and the life cycle of Sycanus sp. The data were calculated, displayed as figures and tables, and given descriptive analysis. The results showed that predatory insects, Sycanus sp., can thrive well by providing alternative feed, such as Black Soldier Fly (BSF) (Hermetia illucens) maggots. Based on the results, it was known that one female Sycanussp. Could produce 101 eggs after being fed BSF maggots, with an incubation period of 17 days. The duration of the nymph stage was around 64.16 days, with a relatively low mortality rate (2-12%). Morphologically, Sycanus sp. grew and developed well. The body length was about twice the width of the body. The age of the male was shorter than that of the female, as was the body size. The sex ratio also showed fewer males than females (2:3).

Abstract

The decrease in corn crop yields in Riau Province was possibly caused by several factors, one of which was the infestation of plant pests such as the corn cob borer (Helicoverpa armigera Hubner). The primary choice for farmers to control H. armigera was using synthetic insecticides, but this could lead to various negative impacts. A solution to reduce the use of synthetic insecticides was the utilization of botanical insecticides, such as those derived from the leaves of chaya (Cnidoscolus aconitifolius I. M. Johnst). This research was conducted with the aim of determining the effective concentration of chaya leaf organic extract against corn cob borer larvae mortality in laboratory conditions. The experiment was conducted in a completely randomized design (CRD) with 5 treatments, each replicated 4 times, totaling 20 experimental units. Each experimental unit consisted of 10 third-instar H. armigera larvae. The concentrations of chaya leaf organic extract used were 0%, 0.25%, 0.50%, 0.75%, and 1%. Parameters observed included initial mortality time, lethal time 50 (LT50), lethal concentration 50 and 95 (LC50 and LC95), daily mortality rate and total mortality. The results indicated that the concentration of 0.75% of chaya leaf organic extract was effective in controlling H. armigera larvae. It caused a total mortality of 82.50%, with an initial mortality time of 6.25 hours and a lethal time 50 (LT50) of 29.75 hours after application.

Abstract

Maize (Zea mays L.) ranks among the major cereal crops globally, after rice and wheat. In Riau Province, a significant decline in maize yield has been observed, mainly due to infestation by fall armyworm (Spodoptera frugiperda J.E. Smith). Control of this pest is essential to prevent its population from exceeding economic thresholds. However, the predominant use of synthetic insecticides has led to undesirable consequences, including the development of resistance, pest resurgence, and secondary pest proliferation. As a sustainable alternative, botanical pesticides derived from plant-based compounds are gaining interest. This study investigated the insecticidal potential of Indian jujube (Ziziphus mauritiana Lamk) leaf extract prepared with 70% ethanol. This plant is known to contain various bioactive secondary metabolites, including alkaloids, saponins, and flavonoids. The experiment was conducted using a Completely Randomized Design with six extract concentrations (0, 0.2, 0.4, 0.6, 0.8, and 1.0%) and four replications, resulting in a total of 24 experimental units. The results showed that a 1% extract concentration produced the highest efficacy, resulting in 82.50% total larval mortality, with initial mortality observed at 7.25 h post-application. The LT₅₀ value was recorded at 52 h, while the LC₅₀ and LC₉₅ were estimated at 0.74 and 1.62%, respectively. These findings suggest that Indian jujube leaf extract has the potential to serve as an environmentally friendly biopesticide for controlling S. frugiperda under controlled conditions.

Abstract

Pulau Rambai Village in Kampa Sub-district, Kampar District is one of the rice production centers. The rice planting for the 2023 planting period failed to harvest due to pests. The solution offered is the use of metankos biological compost and pest control using biopesticides. The purpose of this service activity is the solution offered is the use of metankos biological compost and pest control using biopesticides. The purpose of the service activity is to increase knowledge, skills and empower farmers in making metankos biological compost and biopesticides. The activity methods used are survey, consolidation, counseling, practice and empowerment. The measuring tool for the achievement of service activities is the knowledge and skills of farmers, the method is by distributing questionnaires before and after service activities so that a percentage increase is obtained. Farmers can practice and carry out the service activities that are advised, the level of success is measured by the percentage of farmers who carry it out. Empowerment activities in the form of practice and application of biological compost and biopesticides directly to plants every week through Kukerta students. The service activity was carried out at the Pulau Rambai Village Musholla on Thursday, July 25, 2024. The results of the service activities were an increase in farmers' knowledge of controlling rice pests using biopesticides by 56%, before counseling 100% of farmers had never used biopesticides. Farmers practiced the activities that were suggested in the form of control using biological agents Metarhizum sp and making metankos biological compost was 27.5%. The conclusion of the service activity is that the counseling and empowerment carried out succeeded in increasing farmers' knowledge and empowerment regarding the manufacture of metankos biological compost and biopesticides

Abstract

Siamese orange is a staple horticultural item in Kuok Village, Kuok District, Kampar Regency, although it is under threat from pests and illnesses. Integrated pest management emphasizes ecologically friendly pest control through the use of biological agents. The goal of this service activity is to assist Siamese citrus producers who are hampered by insect invasions and to improve farmers' skills in applying environmentally friendly control technology. Consolidation, surveys, counseling, demonstrations, and mentoring were the methods of implementation. The counseling method consists of forum presentations, questions and responses. Making PDA media, isolating, growing Metharizium sp. and Trichoderma sp., composting were all practices. The service outcomes reveal that the service activities benefit citrus producers in Kuok Village significantly. Farmers understand how to control citrus pests properly. Making PDA media , isolating, cultivating Metharizium sp. and Trichoderma spp. were examples of environmentally friendly management approaches. Farmers responded enthusiastically to the production of methankos.
