Abstract

The aim of this research is to know the most effective concentration of liquid formulation of Kalanchoe pinnata leaf extract 50 EC and Azadirachta indica seed extract 50 EC against S. litura. The experiment was conducted at the Laboratory of Pesticides and Enviromental Toxicology, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The concentration were tested of each formulation were 1%, 2%, 3 %, 4%,and control.  The experiment arranged in completely randomized design (CRD) and replicated three times. The results showed that the formulation of A. indica seed extract 50 EC at concentration of 2%, 3%, and 4% effective against S. Litura larvae with mortality of 76.7%, 86.7, and 93.3%  This formulation also causing a decrease in feeding activity, weight, and lenghten the development time of S.litura larvae. Unlike the case with liquid formulations of K. pinnata 50 EC extract which was less toxic and did not show significant differences in feed intake, weight of larvae, and development time of larvae compared control treatment.                Keywords: Toxicity, mortality, growth dearragement, botanical insecticide.

Abstract

Planococcus minor is one of the pests prohibited from entering several destination countries during the mangosteen export process. Control of P. minor can be achieved by using patchouli and eucalyptus essential oils. The objective of this research is to determine the effects of patchouli and eucalyptus essential oils on the mortality of P. minor, with the aim of developing control measures to prevent mangosteen export failures. This study was conducted at the Class 1 Agricultural Quarantine Station in Bandung from May to December 2023. The method used is the experimental method with a Randomized Complete Block Design. Contact and neurophysiological tests were conducted with 13 treatments, including distilled water control, distilled water + tween 80 control, synthetic pesticide with abamectin 0.005%, patchouli essential oil at concentrations of 0.13%, 0.18%, 0.24%, 0.32%, 0.43%, and eucalyptus essential oil at concentrations of 0.22%, 0.29%, 0.39%, 0.51%, 0.68%, each repeated three times. The research results indicate that mortality of P. minor caused by 0.43% concentration of patchouli essential oil did not significantly differ from abamectin, with a rate of 96.67%. The LC50 values for patchouli and eucalyptus essential oils were 0.19% and 0.42%, respectively. The LT50 value of eucalyptus essential oil is lower when compared to the LT50 value of patchouli essential oil. The LT50 value of eucalyptus essential oil at the highest concentration of 0.68% was 49.94 JSP. Patchouli essential oil at concentrations of 0.43% and 0.32% had different LT50 values of 37.27 and 50.73 JSP. Furthermore, based on morphological observations that eucalyptus and patchouli essential oils affect the morphology of mealybugs.

Abstract

Hermetia illucens L. (Black Soldier Fly) larvae are used as a source of high protein for animal feed, in cultivation they must produce larvae with fast growth and development in large numbers as well as imago with a high reproductive rate. The success factor from the type of feed given, because it can affect the growth and development of the larvae. The research to find a better type of feed for the growth and development of larvae. The research conducted from March 2022 to February 2023 at the Pesticide and Environmental Toxicology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The experiment used a completely randomized design with 4 treatments and 5 replications. The treatment used grain bran feed, rice bran with kale, bran with banana stems, and bran with chicken manure compost. The results showed that the type of grain bran feed with chicken manure compost produced better scores on net reproduction rate (2210.85 females/mother/generation), intrinsic rate of increase (46.43%), population doubling (3.6 days), proportion of live individuals (0.84 individuals), number of eggs (528.8 eggs), average weight (6.534 g), consumption rate (0.0112 g/day), relative consumption rate (0.0104 g/day), growth rate (…0,0123 g/day..), relative growth rate (0,0115 g/g/day), digestibility (3.1940%), efficiency conversion of food consumed (2.0033%), and efficiency consumption of digested food (2,2029%)  with increase respectively 4.58 times, 9.63 times, 4.61 times, 2.1 times, 2.27 times, 3.11 times, 2 times, 2.03 times, 1.14 times, 1.16 times, 2.88 times, 1.98 times, and 3.10 times compared to rice bran feed.
