摘要

The present study is carried out to evaluate the toxic efficiency and delayed effects of five botanical oils on the greasy cut worm Agrotis ipsilon (Lepidoptera: Noctuidae), as a trial for the attainment of a possible use of an alternative safe and effective phytochemicals against the insect-pest. So as to minimize or prevent the repeated usage of conventional insecticides, then reduce the environmental pollution as well as the occurring hazards to man and domestic animal due to the use of the pesticides alone. Four tested concentrations (0.5,1.0,1.5 and 2.5 % v/v) from each of camphor, red basil, menthol, rose and anise oils, were bioassayed by treating the offered castor oil bean leaves, to the 4th instar larvae along 48h, under the laboratory higrothermic conditions of 25±2 °C and 65±5 % R.H.The obtained results showed that the five tested oils were found to have more or less toxic activity and drastic effects on the inspected parameters of fitness components of the treated parent generation of the insect, in particular, pupae, emerged adultmoths and laid eggs/female. In this respect camphor and red basil oils were highly effective, followed by menthol oil, anise oil and the least effective one was rose oil. Moreover, the assessed unprofitable delayed effects on the going on of the biological performance within the treated insects showed the adverse effects on the fitness components of the consequent generations (fs) post (p) one treatment with each of the bioassyed oils. The prevalence of adverse effects and disturbance in the going on biological performance through the period of (p) generation; which is followed by the distinct failure of insect development in (fl) generation were recorded for each of the tested menthol oil at 0.5 and 1.5 % (v/v); camphor oil at 1.5 and 2.5 % and red basil oil at 2.5 % (v/v).While anise and rose oils were somewhat less efficient causing the distinct failure of the following generations up to the 3rd and/or the 6th ones.That observed distinct failure of the insect development could be attributed to the rapid or/and slow cumulative effect of the induced recessive lethal genes in both influenced sexes along the interval of the following developed generations (fs) after (p) one treatment, causing apparent adverse disturbance of the normal biological performance, which finally appears at the beginning of the failed generation.
