Abstract

This study aims to determine the effect of temperature and storage time of neem formulation and residual test of neem formulation and bitung formulation to its toxicity on C. pavonana larvae. The formulations tested on the storability and temperature test using the newly prepared, neem formula has been stored for 19 months at room temperature 24.6-31,7 C, and stored in low temperature (4oC) as well as controls. The toxicity of the neem oil formulation was tested at concentrations of 1%, 2%, and 3%. Residual testing was performed by spraying and the residual test samples were taken on days 0,1,2,3,5,7,9,11, and 13 days after application of insecticide spraying. The results showed that storage at low temperatures (temperature 4oC) for 19 months can maintain the toxicity of the neem formulation to C. pavonana larvae. while storage at room temperature for 19 months resulted in a decreased toxicity. The residual activity of the neem formulations of concentration 0.8% and 2.4% ceased to cause the death C. pavonana larvae at the residual age of 13.34 days and 14.66 days. The activity of Bitung formulation concentration of 1.1% and 2.8% ceased to causing death C. pavonana larvae at the residual age of 11.33 days and 16.26 days.Keyword: Azadirachta indica, Baringtonia asiatica, Crocidolomia pavonana, Residue test, Storability test, Temperatures, Toxicity,

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.

Abstract

Effectiveness of pesticide affected by many factors such as physical environment and duration of storage. This study aims to determine the effect of temperature and storage time of formulation of neem 50 EC and residual effect of formulation of neem 50 EC and formulation of bitung 30 SC against C. pavonana larvae. The formulations tested on the experiment of effect storage time and temperature test using the newly prepared, neem formulation has been stored for 19 months at room temperature 24.6-31.7oC, and stored in low temperature (4oC) as well as controls. The toxicity of the neem oil formulation was tested at concentrations of 1%, 2%, and 3%. The experiment of residual effect was performed by spraying of the formulation on broccoli leaf, then the leaf samples were taken on days 0,1,2,3,5,7,9,11, and 13 days after application of insecticide. The results of the research indicated that storage at low temperatures (temperature 4oC) for 19 months can maintain the toxicity of the neem formulation to C. pavonana larvae. while storage at room temperature for 19 months resulted in a decreased toxicity. The residual activity of the neem formulations at concentration of 0.8% and 2.4% were not caused mortality of C. pavonana larvae at the residual age of 13.34 days and 14.66 days. The activity of Bitung formulation at concentration of 1.1% and 2.8% were not caused mortality of C. pavonana larvae at the residual age of 11.33 days and 16.26 days.

Abstract

An important pest in corn plantation recently reported in Indonesia was Spodoptera frugiperda, a polyphagous pest that have a fast spread rate and caused high damage on young corn. One control that able to use is botanical insecticide. This experiment aims to determine the toxicity of neem, jatropha, clove, and citronella oil (concentrations of 0.1% and 0.05%) against S. frugiferda in corn. Tests carried out using the feeding assay or residue on corn leaves (size 5 x 5 cm). Then, the leaf treatment was given to 10 larvae of S. frugiferda (instars 2) for 48 hours. After that, the feed replaced with untreated feed. The test results showed that concentration neem oil of 0.1% caused the highest mortality of S. frugiferda. Neem oil exposure is also able to inhibit the time of larval development, reduce the percentage of feed consumption, and the weight of pupa the S. frugiferda. Other vegetable oils exposure gave lower mortality in the test insects and some treatments were not significantly different from the controls on the parameters of larval development, pupae weight, and percentage of feed consumption. Neem oils showed strong toxicity against S. frugiperda larvae with  Lethal Concentration 50 (LC50) of 0.079 % (CI (95%) 0.066 – 0.095%) and LC95 of 0.338% (CI (95%) 0.024-0.567%).

Abstract

Brown Planthopper is one of the pests that cause problems in rice production. This study was conducted to know the tendency of using a kind of insecticide and to examined the susceptibility of brown planthopper from field population (Cipunagara, West Java) compared to standard population (Banyuwangi, East Java) to formulation insecticide of neem oil 50 EC. Observations wereconducted on Cipunagara farmers to find out the kind of insecticide used and the number of insecticide applications in one season. the susceptibility test to neem oil 50 EC formulation was conducted by root dipping method. Brown planthopper was feed on treated plant for two days and then the next day the Brown Planthopper was fed on rice plant without treatment until the eighth day. Test insects used are brown planthopper instar 4th. Observations of insect mortality test for ten days with an interval of every 24-hour observation. Susceptibility values for neem oil insecticide formulations were determined based on the resistance ratio (RR) by comparing the LC50 value of the field population and standard population. Result of the observations showed that the farmers in the Padamulya village, Cipunagara district generally using synthetic insecticides to control of this pest. The active ingredient of most mentioned was imidacloprid with a lot of different applications. The result of examination of insecticide formulation of neem oil 50 EC using the root dipping method showed that a slow death trend and the highest mortality at eight days after application. The LC50 value of neem oil 50 EC insecticide against brown planthopper in the field population (Cipunagara) was 0.36% and RR 0.98. The result indicated that brown planthopper origin from Cipunagara was still susceptible to neem oil 50 EC insecticide formulation.Keyword: Neem oil formulation, Susceptilbility, Resistance ratio, Brown Planthopper

Abstract

This study aimed to obtain resistance information of S. litura from Karangpawitan and Lembang districts (West Java, Indonesia) against chlorpyrifos insecticides (200 g/l) and their sensitivity to oil mixture of A. indica and C. nardus (1:1) using feeding and topical assay. The activity of acetylcholinesterase, esterase, and glutathione s-transferase from S. litura larvae in both populations were tested to determine their role in insect resistance. Results showed that S. litura population from Lembang had a higher level of resistance to chlorpyrifos compared to Karangpawitan. The sensitivity of the two S. litura populations had a relatively similar resistance ratio (RR) value of less than 1 to botanical insecticide. These indicated that resistant population could be controlled by a mixture of this botanicals insecticide. Enzyme activity test indicated that chlorpyrifos at a concentration of 0.26% could inhibit the acetylcholinesterase activity of insect population from Karangpawitan by 98.66% while those from Lembang, it was only 35.31%. Specific activity of esterase from Karangpawitan was 13.37 units/mg while Lembang population was 119.65 units/mg. The specific activity of the Glutathione S-Transferase (GST) of Karangpawitan population was 1140.82 units/mg while Lembang population was 793.73 units/mg. The high activity of the three enzymes could be responsible for resistance of S. litura larvae to chlorpyrifos.
