Abstract

Larvicidal and antifeedant activities of clove leaf oil against Spodoptera litura (F.) on Soybean. Economic losses due toinfestation by the soybean armyworm, Spodoptera litura can reach up to 100%. Some farmers often used insecticide to control thearmyworm. However, regular use of insecticide can cause several negative effects such as environmental pollution, residual toxicity,and health hazard for human. The objective of this research was to determine the larvicidal, antifeedant, and activities of cloveleaf oil (CLO) against the armyworm S. litura on soybean. The research was carried out at the plant pest control laboratory ofPoliteknik Pembangunan Pertanian Malang. Clove leaf oil was evaluated for its larvicidal and antifeedant activities against tenthird instar larvae of the armyworm. Completely randomized design was used with concentration levels of CLO as treatments.i.e. 0.4, 0.5, 0.67, 1.0, and 2.0% by volume. Profenofos 500 g L 0.1% and distilled water were include as control. Each treatment consisted of five replications. Mortality of the larvae and antifeedant activity were analyzed using analysis of variance, followed by probit analysis for calculating LC 50  and LT 50-1. The results showed that CLO at 2.0% concentration was the most effective with regard to larvicidal and antifeedant activities. The LC 50 of CLO was 0.09% with LT 24.6 hours. This study revealed that the environmentally friendly CLO can be used as an alternative to synthetic insecticide for control S. litura.

Abstract

Fall armyworm or Spodoptera frugiperda is one of the main pests of corn. It can caused up to 28.08% yield loss. Pest control efforts with broad-spectrum insecticides can cause negative impacts that disrupt ecosystems, non-target biotic factors and the surrounding environment. Beauveria bassiana is an alternative biological control agent that is target-specific. This study was conducted to determine toxic and antifeedant activities of B. bassiana application on third to fifth-instar S. frugiperda larvae. B. bassiana isolates were propagated using corn flakes media and resulted in colonies with conidia density of 1.1×108conidia.g-1. This study used a completely randomized design with 5 treatments and 5 replications. Treatments consisted of P1 namely B. bassiana propagation with a concentration of 60 g.L-1, P2 = 70 g.L-1, and P3 = 80 g.L-1. P0 was a negative control (untreated with B. bassiana) and P4 was a positive control (diazinon with concentrations of 2 ml.L-1). The variables observed were mortality and weight of the leftover feed. The results showed that the formulation of B. bassiana with concentrations of 80 g.L-1 was able to infect armyworms with a mortality percentage of 53.5% which was statistically similar as the effect of chemical insecticides. In addition, inhibition of feeding activity due to treatment could prevent leaf damage up to 68.21%.

Abstract

Bujangseta is a technology used throughout the year to produce citrus fruits. This technology has economically succeeded in increasing the income of citrus farmers by 23.5%. Sustainable management of bujangseta technology is neede, one of which is maintaining the sustainability of the agroecosystem. A stable agroecosystem ensures the availability of ecosystem services through nutrient cycling and the natural control of pest and disease populations. The stability of agroecosystems is coherent with the high biodiversity of arthropods. This study aims to evaluate the effect of applying the citrus plant bujangseta in Karangwidoro village and Krajan village, Dau District, Malang Regency, East Java, from June to December 2022. The two application methods were light trapping (lighttrap) and pit trap (pitfall glass), and the results were analyzed using a t-test. The diversity index, species richness index, species evenness index, and dominance index were calculated. The results showed that the detrivores of the Collembola group dominated the diversity of arthropods, the primary pest of the Diaphorina citri, and the predatory arthropods of Paederus sp. and Braconidae. Diversity and community structure of arthopods indicated there at significant differences in diversity, dominance, evenness, and species richness in those two locations. Bujangseta in the Krajan has a higher community structure compared to the Karangwidoro, showing that the ecosystem at the Krajan location is better preserved. Keywords: arthropods, bujangseta, citrus, community structure
