Abstract

One of the main problems in Chinese cabbage culture is the destruction by insect pests. Normally, the beet armyworm, Spodoptera exigua, is the major insect pest in Chinese cabbage produced in Thailand. The aim of this experiment was to study the influence of plant essential oils as growth inhibitor against the secondary stage instar larvae of the beet armyworm. The essential oils from Illicium verum, Curcuma longa, Foeniculum vulgare, and Ocimum tenuiflorum at varied concentrations; 0.00, 0.25, 0.50, 0.75, 1.00, and 1.25 % (v/v) and ten secondary stage instar larvae were used at each level of concentration in the experiment with 3 replicates. The growth stage, the development period from larva to pupa, and pupa to adult stage, and the percentage of mortality were observed. The results showed that the highest growth inhibition was at 0.75% concentration of Illicium verum and Curcuma longa. The percentage of mortality of pupa and adult stages were 100% at 0.75% concentration of Illicium verum and Curcuma longa. The development period from larvae to pupa was 5.67±5.77 days at 0.50% concentration of Illicium verum and Curcuma longa. The development period from pupa to adult was 8.67±5.77 days at 0.50% concentration of Illicium verum and Curcuma longa. The result also showed that at 0.50% concentration of Illicium verum and Curcuma longa, the development period of beet armyworm from larvae to pupa stage and from pupa to adult stage was less than the development period of the control group. As a result, the growth stage was incomplete and the survival rate was affected. Therefore, these essential oils can be developed as the effective botanical insecticides against the beet armyworm.
