Abstract

This study aims to evaluate the bioactivity of the Neem formulation  against Crocidolomia pavonana larvae in the laboratory. The study using six treatments and three replications. The treatment consisted of control, the neem formulaconcentrations of 0.3%, 0.5%, 0.8%, 1.3%, and 2.3%. The test was done by leaf feeding method and tested on C. pavonana instar II. The results showed that the neem formulation 2.3% could increase mortality of C. pavonana larvae with mortalityrate of 95% population and LC  value aqual to 0.82973. Neem formulation can inhibit the development of C. pavonanalarvae from instar I to instar IV, decrease feed intake, and decrease the dry weight of C. pavonana larvae instar IV. Keywords: Azadirachta indica, Bioactivity, Crocidolomia pavonana, neem formulation

Abstract

Fall armyworm (Spodoptera frugiperda) is a new pest that attacks maize plantations in Indonesia. Local farmers generally use synthetic pesticides to control the pest that can cause environmental and health problems, and in the future will trigger resistance of the pest to insecticide. This study aimed to determine the potential of Sphagneticola trilobata flower extracts on mortality, larval weight, weight of food consumption, and inhibition of feeding activity in S. frugiperda larvae. The research method is completely randomized design with 6 treatments and 3 replications. The treatments consisted of control treatments, S. trilobata flower extract 1%, 2%, 3%, 4%, and 5%. Mortality, larval weights and food consumption data were analyzed using analysis of variance. The results showed that the S. trilobata flower extract at the highest concentration of 5% resulted in larval mortality of 72.22. These results indicated that the S. trilobata flower extract was not effective against S. frugiperda. However, S. trilobata extract can influence other biological aspects, such as feeding activity and growth of S. frugiperda larvae. Tratment of 5% of S. trilobata extract resulted in weight of feed comsumption of  0.123 g with inhibition of feeding activity of 66.11%, and average weight of larvae of 0.048 g that were lower than control treatment.

Abstract

Spodoptera frugiperda is a pest that is capable of migrating over a wide range. Currently, the S. frugiperda attack can be said to be comprehensive in almost all regions of Indonesia. The level of adaptability of S. frugiperda to the suitability of the agroecosystem needs to be reviewed further in order to predict the potential for S. frugiperda attacks in the future. This research aims to test the suitability of temperature for the biological activity of  S. frugiperda. The treatments tested in this study included temperatures (A) 34.0±2.2 oC, (B) 27.0±4.1 oC, and (C) 19.0±1.3 oC. Each treatment used 5 larvaes 2nd instar and was repeated 6 times so that the number of test insects used was 120. The parameters observed in this study included growth, development, feeding activity and mortality rate of the test insects. The data obtained was then analyzed using ANOVA and tested further with DMRT at an error level of 5%. Differences in rearing temperature can affect growth, development, feed consumption and larval mortality. Temperature (B) 27±4.1 ℃ is the most suitable temperature for S. frugiperda. Temperatures (A) 34.0±2.2 ℃ and (C) 19.0±1.3 ℃ are less suitable temperatures, but S. frugiperda can still carry out its life cycle. This research can provide an overview to anticipate S. frugiperda attacks that may occur due to global warming in the future.
