  In last decades, many researches have been done on use of botanical compound especially essential oils as insecticides. In the present study, the contact toxicity of Lavandula angustifolia and Zataria multiflora essential oils was evaluated on both sexes of C. maculatus adults at 29±1ºC, 60±5% RH in dark condition. Essential oils were obtained by hydro distillation. The toxicity of both oils against males and females was positively and significantly associated with concentration. On the basis of LC50 ratios and their 95% confidence limits, there was no significant difference  between sensitivity of males and females. The LC50 values for  males were 719 and 598 µl.m-2 and for females were 787 and 738 µl.m-2 for L. angustifolia and Z. multiflora, respectively. Both       essential oils had no negative effect on seed germination of the cowpea. The essential oils analysis by GC-MS showed that the main compounds 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%) and those of Z. multiflora oil were thymol (55%), linalool (37.8%) and p-cymene (7.2%). The results suggested that L. angustifolia and Z. multiflora essential oils might be suitable alternatives to conventional pesticides for protecting pulses against C. maculatus adult.

  Bracon hebetor say bee is one of the most important biological control factors that can be effective in controlling larvae of lepidoptera pests such as Helicoverpa armigera hubner at acceptable economic level. The present review was aimed at studying probable adverse effects of Achillea millefolium, Lavandula angustifolia, and Mentha piperita plants extracts on adult insect of the B. hebetor bee. The bee was grown on last instar larvae of Ephestia kueheniella Zell. All bioassay experiments were carried out at temperature of 26±1 °C and relative humidity of 60±5, and under photoperiod conditions of 16 hours of lightness and 8 hours of darkness. Findings of the study indicated that spearmint plant had the highest lethal effect on adult insect of B. hebetor bee in fumigant and contact toxicities and other plants, respectively, Achillea millefolium, Lavandula angustifolia, and Mentha piperita had the least lethal effect on adult insect of B. hebetor bee in fumigant and contact toxicities. The estimated LC50 value for spearmint plant at 48 hours was 6 microliters/ml in fumigant toxicity and 3.2 microliter/ml in contact toxicity. Repellency effect of spearmint, Achillea millefolium, Lavandula angustifolia, and Mentha piperita plants extracts was studied on adult insect using tube -Y olfactory-meter device. Cotton wool soaked with the extract was placed at one end of the device and the other end was closed with web and the insects were released in the main branch. Each iteration of the experiment was conducted on 20 insects. Results of analysis of variance (ANOVA) of the data related to repellency effect of the studied extracts indicated that being a stronger repellant compared to other two extracts, spearmint extract with lower concentration can repel adult insects of B. hebetor bee.
