Abstract

Resistance is a decrease in the level of sensitivity of a pest populations that causing a previously effective pesticides becoming ineffective. This case is caused by inappropriate insecticides application, continuous use, only one type of pesticide and usage for long periods of time. There are a lot alternative source of insecticides which is more effective and environmentally friendly. One alternative source of insecticides that can be used for pest control is plants. This study aimed to determine the potential toxicity of methanol extract of N. tabacum, B. asiatica, V. zizanoides, A. indica, and T. vogelli on the mortality and development time of A. aegypti mosquito larvae. The research was conducted at the Laboratory of Pesticides and Environmental Toxicology, Department of Plant Pests and Diseases, Faculty of Agriculture, Padjadjaran University, Jatinangor. The experiment was performed using a Completely Randomized Design (CRD) with 6 treatment and 4 replication. The result showed that methanol extracts of the test material were toxic to the larvae A. aegypti with the highest the lowest toxicity were at the concentration of 0.001% i.e treatment of T. vogelli, N. tabacum, B. asiatica, A. indica, and V. zizanoides with the successive rate of mortality (45%, 65%), (37.5%, 60%), (32.5%, 50%) and (32,5%, 47.5%). Besides being toxic, the methanol extract also influenced development of A. aegypti larvae. The pH levels and the dissolved oxygen content of the tested methanol extract solution at the concentration of 0.005% in each treatment are not much different when compare with controls.

Abstract

One of the main pests that attack rice plants is the brown planthopper (BPH) or Nilaparvata lugens Stål. The negative impact of synthetic insecticides that have been used to control BPH causing increased desire to return to nature with the use of natural materials for plant  protection. One source of natural ingredients that can be used in plant protection can come from plants as a botanical insecticide. Several plant species are known to have the botanical insecticidal activity such as Ageratum conyzoides (Asteraceae), Barringtonia asiatica (Lechytidaceae), Melia azedarach (Meliaceae) and Tephrosia vogelii (Fabaceae). In this research, toxicity testing was performed on extracs of A. conyzoides, B. asiatica, M. azedarach and T. vogelii to BPH, and its phytotoxicity on rice plants. The research was conducted using Completely Randomized Design (CRD) in experimental toxicity test of plant extract and phytotoxicity test on rice plant was done using 2 concentrations of 0.1% and 0.5% in each plant extract, and used 0.5% concentration on anti-oviposition effect. The results showed that T. vogelii methanol extract with 0,5% concentration caused the highest nymphs brown planthopper mortality which was 42,5% and at concentration 0,5% the four plant extract did not cause inhibition of oviposition activity on the BPH and did not cause phytotoxicity in rice plants.

Abstract

Oil palm is a pre-eminent commodity in Indonesia, especially in Riau Province. The main pests that attack the oil palm is the pest of beetle Oryctes rhinoceros. The life cycle of pre-adult O. rhinoceros is on the ground, while the one that attacks the plant is the beetle stadia. The application of oil palm empty bunches (OPEB) to oil palm cultivation that functions as mulch and soil compost can improve the physical and biological properties of the soil, otherwise O. rhinoceros actually increases its population with OPEB application. The objective of this research is to know the population of O. rhinoceros in oil palm plantation given mulch of empty palm oil bunches. Research using survey method, observation done at PT. Adei Plantation & Industry. Observations made on the pradati with the size of the soil as a sample, to catch the adult beetles used ferotrap using pheromones as much as 5 ferotrap on 10 ha of land. Observations included the pre-adult population, the beetles population of O. rhinoceros, sex ratio, biomass, attack intensity. The results of research that has been done showsthat in the low adults population were the average of 8 tails per week, instar 2 most found was 15 tails. The population of beetles O. rhinoceros were the average of 23.8 tail / ferotrap / month. Population O. rhinoceros 1st week and 2nd, 3rd week decreased, lowest was at 4th week. The sex ratio of female and male beetles was 19.4: 4.4 or 4.54: 1.

Abstract

Aedes aegypti is known as the main vector of dengue fever in Indonesia which causes a high number of deaths and become an outbreak every year. This disease is generally controlled by breaking the life cycle of mosquitoes with restricted breeds and using synthetic insecticides. So far biological agents from natural enemies and natural pathogens have been developed to anticipate the negative effects of synthetic insecticides. Bacillus thuringiensis is well known as entomopathogenic bacteria that can control various insect pests of cultivated plants and vector insects, such as Ae.aegypti.  B. thuringiensis can form endospores that produced toxin to Ae.aegypti, while the advatages are safe against non-target organisms such as natural predators and parasites, safe for mammals and humans and do not pollute the environment. Effective duration of B. thuringiensis in infecting Ae. aegypti is an important thing to be studied, moreover it is important to know the effectiveness of the expired formulation on the market and the residual effect. This ensures that the use of B. thuringiensis remains safe and does not create new problems such as Ae. aegypti  resistance. The experimental research was used bioassay method, toxicity test was performed B. thuringiensis expired and non expire as comparison at concentration 0 ppm (control), 0,3 ppm; 0.1 ppm; 0.07 ppm; 0.05 ppm; 0.03 ppm; 0.01 ppm. The parameters observed were mortality for 48 hours of toxicity test that results were indicated by LC 50, LC90 and recidual values. The results obtained were LC50 and LC formulations B.thuringiensis expired 0.305 ppm and 1.513 ppm much higher than the non expire LC50 and LC formulations of 0.0363 ppm and 0.8971 ppm. The recidual effect of expired B. thuringiensis on larvae Ae. Aegypti was only effective until day 12, whereas B. thuringiensis  that  non expire formulation was effectively until day 14.Keywords : Ae. aegypti, B. thuringiensis, mortality, recidual values, expired formulation
