Abstract
Potato tuber moth (Phthorimaea operculella Zeller) is a key pest of potato for storage and field as well. In order to determine the efficacy of novel pesticides a bioassays was done using different pesticides selected at different concentrations. An experiment on “Determination of the efficacy of novel pesticides against potato tuber moth (Phthorimaea operculella Zeller) in laboratory condition on seed potato” was carried out in the Laboratory of Entomological Division, NARC, Khumaltar, Lalitpur from 20th April 2022 to 20th August to determine the efficacy of novel pesticides used to control against potato tuber moth. Bioassays were used to determine the effect of pesticides selected at different concentrations. Mass rearing of potato tuber moth was conducted, and the temperature and humidity were also noted in the laboratory (±27˚C) and ±70%. The different biological features and the damage index of potato tubers have been evaluated and found to be highest on Bacillus thuringiensis, the highest mortality% was studied, and the live population and adult emergence were reported highest at the mid-time of trial. The study revealed the effectiveness of the pesticides against potato tuber moths, three pesticides Chlorantraniliprole, Spinosad, and, Bacillus thuringiensis have higher efficacy than Bojho and the mortality rate was Chlorantraniliprole (100%), Spinosad (85%), Bacillus thuringiensis (70%) whereas, the lowest mortality rate in treatment Bojho (60%). High Infestation was also seen in Bojho as compared to the other three pesticides. All the novel pesticides used were found to be effective against the pest in reducing the population in laboratory conditions; however, their effectiveness was directly proportional to the concentration and exposure periods. The study has demonstrated the possibility of using novel compounds against potato tuber moth in storage condition potato.
