EVALUATION OF INSECTICIDE AND NANOINSECTICIDE EFFICACY AGAINST MEALWORM (Tenebrio molitor) AND SUPERWORM (Zophobas morio) IN VITRO
The increase in global population has also increased the need for food. The fulfillment of food needs certainly cannot be separated from the agricultural sector. Unfortunately, in recent years, the increase in population growth in Indonesia has not been in line with the increase in agricultural production. Pest attacks are a big problem that will have an impact on the fulfillment of food needs. The attack of a pest species cannot be underestimated and left alone, but needs to be controlled. The most common control currently carried out in controlling pest attacks is chemically using synthetic insecticides. Chemical control using synthetic insecticides is favored by farmers because synthetic insecticides are considered effective in controlling pests. Another factor that supports chemical insecticides to be favored by the public is the relatively low cost when compared to other controls, especially if they have to be applied to a large area. nanoformulations increase the efficiency of insecticide work. Increased efficiency in nanoformulations will reduce the amount that must be used so that it can reduce costs in control. Nanoformulation allows active ingredients to be released under controlled circumstances, even in unfavorable environments. This research was conducted at the Center for Development and Application of Environmental Technology, Vietnam Academy of Science and Technology, Hanoi, Vietnam. The implementation time of this research began in November 2023 and ended in January 2024. This research was conducted by observing the number of deaths of Tenebrio molitor and Zophobas morio test insects in vitro. The data that has been obtained then the data is presented in a structured form and analyzed using the SPSS Statistics data processing program. Mortality data that has been obtained after the application of active compounds, abamectin and emamectin in tabulated form. The data was then processed using microsoft excel and spss statistics. Based on the data obtained, the mortality percentage of the active compound emamectin is much higher than the active compound abamectin, even at each dose. This can occur because nano insecticides have a smaller particle size when compared to regular insecticides. The smaller particle size allows deeper penetration into the insect cuticle. This can certainly increase the efficacy of nano insecticides. Based on tables 1 and 2, abamectin in the first observation or 12 hours there is no value of LD50. This is because in the first observation, there was no mortality. then in table 3 it decreased by 30.12mg, and in table 4 it decreased by 88.44mg. The decreasing LD50 value indicates that to kill 50% of the population faster, the more insecticides are needed. It can also be seen from table 5, table 6, table 7, and table 8 that the LT50 values of the 20mg dose, 40mg dose, 60mg dose, and 80mg dose have decreased. This decreasing LT50 value provides information that the higher the dose used, the faster the time used to kill 50% of the test insect population, and vice versa, namely the lower the dose used, the longer the time used to kill 50% of the test insect population
