Abstract

The decline in productivity of Acacia seedlings (Acacia crassicarpa) in Industrial Plantation Forests is caused in part by attacks of mealybug pests (Paracoccus marginatus). Using chemical insecticides in pest control can negatively impact health and the environment, so more environmentally friendly alternatives are needed, such as plant-based insecticides. This study aims to determine the concentration of noni leaf extract on the mortality of mealybug pests. A completely randomized design (CRD) was employed, consisting of four treatments with different concentrations of Morinda citrifolia leaf extract (30 g/l, 40 g/l, 50 g/l, and 60 g/l), each replicated three times. The observed parameters included the time of initial death, Lethal Time 50 (LT₅₀), and total mortality percentage. The results indicated that the use of Morinda citrifolia leaf extract of 60 g/l was the most effective, with an average time of 8,67 hours, LT₅₀ of 24,67 hours, and total mortality rate of 100% for Paracoccus marginatus.

Abstract

Plutella xylostella are one of the pests that attack BPDASHL (Watershed against hanging Plutella xylostella pests on Phitecellobium jiringa plants. This study botanical pesticide, used a completely randomized design (CRD), with the treatments namely: P1 = a pest control, Citrus mixture of C. aurantifolia leaf extract and P. betle leaf 50 g/L, P2 = a mixture of C. aurantifolia, Piper aurantifolia leaf extract and P. betle leaf 100 g/L, P3 = a mixture of C. aurantifolia betle, nursey leaf extract and P. betle leaf 150 g/L, and P4 = a mixture of C. aurantifolia leaf extract and P. betle leaf 200 g/L. The observation variables in this study were temperature and humidity, the initial time of death, lethal time50 (LT50), daily mortality, and total mortality. The results showed that the application of botanical pesticide extract of C. aurantifolia leaf and P. betle leaf was efficient on the mortality of hanging P. xylostella pests with a total mortality result of 100%. The best the best concentration is a mixture of C. aurantifolia leaf extract and P. betle leaf 200 g/L (P4).
