Abstract

Maize weevil, Sitophilus zaemais (Motschulsky) is one of the most important economic pests that seriously damages stored grain. It has caused massive losses in stored grains, especially maize which can be solved by the insecticidal property of various essential oils. Six essential oils of Cinnamomum, citronella, mentha, lemongrass, clove, and neem oil at the rate of 1ml/200 gm maize seeds were tested for efficacy to control maize weevil under laboratory conditions. Seven treatments including control (no botanicals) were replicated three times in a completely randomized design (CRD). The experiment was conducted in the Entomology Lab of Lamjung Campus where the temperature was 20-27°C during the daytime and relative humidity was 75% during the Experimentation period. The collected data were subjected to statistical analysis considering factorial ANOVA. Treatments were found to be significantly differed in Exit hole number, weight loss, Germination percentage, and weevil mortality number compared to untreated checks (control). Mentha Oil was significantly more effective than the rest of botanical Oil and control. In general, the result showed that the lowest number of exit holes (0.00) and lowest weight loss (200gm) were found in Mentha Oil and the highest germination percentage (87%) was found in both Mentha and Neem Oil. Similarly, the highest number of dead weevils were found in Mentha (10.00) up to 96 hours.
