Abstract

Plutella xylostella are one of the pests that attack BPDASHL (Watershed Management Agency and Protected Forest) nurseries in Pekanbaru. One of the plant seedlings attacked by this pest is the Phitecellobium jiringa. Pest control efforts that have a positive impact are botanical pesticides. This study aims to determine the best concentration of a mixture of Citrus aurantifolia leaf extract and Piper betle leaf against hanging Plutella xylostella pests on Phitecellobium jiringa plants. This study used a completely randomized design (CRD), with the treatments namely: P1 = a mixture of C. aurantifolia leaf extract and P. betle leaf 50 g/L, P2 = a mixture of C. aurantifolia leaf extract and P. betle leaf 100 g/L, P3 = a mixture of C. aurantifolialeaf 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).

Abstract

The vegetation and wildlife of Gunung Halimun Salak National Park (GHSNP) are quite diverse. Ants (family: Formicidae) are among the diversity's less studied components. The hilly terrain of Gunung Halimun Salak National Park has not seen considerable alterationOne of the more fascinating aspects of studying wildlife is insects, particularly ants. Research on ants in the mountains at different elevations has been scarce up to this point. The purpose of this study is to examine the ant community at seven different elevations in terms of abundance, variety, and community similarity and to determine how ant diversity and environmental factors relate to one another. The soil arthropods were collected using pitfall traps, placed in several altitudes, i.e., 500 m, 700 m, 900 m, 1100 m, 1300 m, 1500 m, and 1700 m . Overall, 1536 ants were measured for abundance throughout all high-altitude habitats. At 700 m, the greatest number of arthropods (365 individuals) was found. There were just 85 ants at the maximum elevation of 1700 meters, which was the lowest ant abundance. The dominant morphospecies of the order Hymnoptera/ants (Formicidae) were Pheidole sp. and Polyarchis sp.

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

One of the pests that attacks Eucalyptus pellita is Paracoccus marginatus. Currently, chemical pesticides are used to control these pests, which can harm health and the environment. As a result, we need a more environmentally friendly alternative biopesticides that comes from a combination of Carica papaya leaf and Tinospora crispa stem extracts. The aim of this research was to determine the effect of Carica papaya leaf and Tinospora crispa stem extracts on Paracoccus marginatus pests in eucalyptus nurseries and to determine the best concentration for controlling Paracoccus marginatus pestsThe experiment used a completely randomized design (CRD) with 4 treatments and 4 replications. The treatments consisted of different concentrations of Carica papaya leaf and Tinospora crispa stem extracts (20, 40, 60, and 80 g/l). This was followed by a DNMRT test at 5% confidence level. The results showed that the combination of Carica papaya leaf and Tinospora crispa stem extracts significantly affected Paracoccus marginatus mortality. The best concentration of the extract mixture was 80 g/l, which resulted in the fastest mortality rate, with an LT50 of 26.41 hours and 100% total mortality.

Abstract

Pests and diseases are recurring issues in the cultivation of forest plant seedlings, as they can reduce seedling quality and lead to economic losses due to seedling mortality. Identifying the types of pests and diseases is crucial for implementing more effective, efficient, and environmentally friendly control measures to maintain seedling quality. The methodology used in this study was a field survey with direct observation of seedlings affected by pests and diseases. Data collected included the types of pests and diseases observed in various seedlings, such as Annona muricata, Albizia saman, Archidendron pauciflorum, Parkia speciosa, Nephelium lappaceum, Pometia pinnata, Persea americana, Durio zibethinus, Garcinia mangostana, and Artocarpus heterophyllus. Observations were conducted over an eight-week period. The damage caused by pests and diseases in the BPDASHL nursery was categorized as relatively mild. Common pests identified included beetles, borers, and mealybugs. Meanwhile, diseases frequently observed were yellowing leaves, sprout collapse, stunted growth, and leaf spot.
