Abstract

Inhibitory effects of Lavandula angustifolia and Zataria multiflora essential oils were evaluated on reproduction and F1 progeny production of Callosobruchus maculatus. Insect’s culture and bioassays were conducted at 29 ±1ºC, 60±5% RH and dark condition. Essential oils were taken by hydrodistilation. The results indicated that there was a negative and significant linear relationship between reproduction of beetles and oil concentration. Similar relationship was found between F1 progeny and oil concentration. Comparison of regression slopes showed that L. angustifolia oil was more effective than Z. multiflora oil on reproduction and F1 progeny population. The essential oils analysis by GC-MS showed that the main compounds of Z. multiflora oil were Thymol (55%), Linalool (37.8%) and p-Cymene (7.2%) and those of L. angustifolia oil were Linalool (42.8%), 1, 8-Cineol (23.4%), Rosefuran epoxide (14%), Menthone (6.8%), Isomenthol (5.2%) and Dihydro carvone (trans) (4.3%). The results indicated that these essential oils especially L. angustifolia oil might be suitable alternatives for stored products protection against C. maculatus
