Fumigant activity of essential oil vapours from the aromatic plants such as, wild thyme (Thymus serpyllum L., Lamiaceae), origanum (Origanum onites L., Lamiaceae), rosemary (Rosmarinus officinalis L, Lamiaceae), basil (Ocimum basilicum L., Lamiaceae) and lemon balm (Melissa officinalis L., Lamiaceae) against the bean weevil Acanthoscelides obtectus (Say) adults under laboratory conditions. Volatile phase effects of different concentrations of the essential oils were used to determine insecticidal activities. Laboratory bioassay results indicated that all essential oils were found to cause 100 % adult mortality of A. obtectus in a dose-dependent manner. Essential oils of thyme and origanum had the highest insecticidal effects, causing high adult mortalities at the lower concentration (10 µg mL-1 air) in comparison to other essential oils tested. Adult viability was totally affected by essential oils of rosemary, basil and lemon balm at the concentrations of 20, 30 and 30 µg mL-1 air, respectively. The estimated LC50 (lethal concentration 50) values obtained for each essential oil were calculated by using probit analysis. The lowest LC50 values were recorded for thyme essential oil (1.12 µg mL-1) was followed by origanum (1.31 µg mL-1), rosemary (2.66 µg mL-1), basil (3.10 µg mL-1) and lemon balm (3.60 µg mL-1) respectively. The results of the present study concluded that plant essential oils could be useful in promoting research aiming at the development of new agent for pest control from the plants with medicinal values.

) and Rhopalosiphum padi L. were intensively found on weeds in the potato fields. Potato leaf samples showing yellow spots and patterns, and then severe chlorosis were detected by serological (DAS ELISA: Double antibody sandwich-Enzyme linked immunosorbent assay) and biological indexing methods. AMV was detected in Physalis angulata by the rate of 15.3% in 2014. Although, AMV infection was found in low levels in symptomatic potato plants in 2014 and 2015 (5.4% and 4.6%), AMV is important in Amik plain due to the virus can be transmitted by vector aphids to weeds and other crops mainly growing in Amik plain such as alfalfa, tomato and pepper or from these sources to potatoes. AMV infection began to be affected potatoes grown in Hatay during the last few years. Seed tubers infected by AMV are thought to be the source of the virus infection of potatoes growing in Hatay-Turkey. For monitoring of the status of the virus in potato fields over the years, the studies on AMV infection on potatoes, weeds and other hosts are in progress.
