INSECTICIDAL EVALUATION OF ANISALDEHYDE AGAINST Rhyzopertha dominica [COLEOPTERA: BOSTRYCHIDAE].....
Under laboratory conditions, the insecticidal potential of Anisaldehyde against the survival of R. dominica infesting wheat grain is investigated. The research was carried out at the Federal University of Technology Akure's Crop, Soil, and Pest Management Research Laboratory. With three replicates, the chemical was tested at 10, 20, 30, 40, and 50 l /20g of wheat. Adult mortality, adult emergence, percent inhibition rate, and weight loss were all monitored over the course of four days. Anisaldehyde's route of action, which involves neurotransmitters and digestive enzymes, was also observed. The 50 l dosage was shown to be the most successful among the treatments, with 93.33 percent insect mortality within 24 hours of treatment and a statistically different effect (p 0.05) from the other treatments. Only 40 and 50 litres of the chemical were able to reach 100% insect mortality, although their effects were not substantially different (p > 0.05) from the 30 litre dosage, which recorded 86.67 percent insect mortality. The results revealed that 1.14 and 5.27 l of the compound are required to achieve 50 and 95 percent insect death at 72 hours post-treatment, respectively. Both the 40 and 50 l dosages resulted in 0 percent adult emergence, 100% inhibition rate, and no weight loss. Acetylcholinesterase activity was completely inhibited by the 50 l dose, however there was a substantial difference in lipase and other enzyme activity. Anisaldehyde molecule was clearly effective based on all observations. The findings also revealed that, because of its promising insecticidal capability, it might be utilised as an alternative to synthetic chemical insecticides for the overall control of stored goods insects.
