Abstract Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) is one of the most harmful, world-wide known pests of greenhouse crops and ornamental plants. This insect feeds on plant sap, produces honeydew, and transmits plant viruses, while causing quantitative and qualitative damage to plants. For controlling this pest in greenhouses, plant essential oils are used as an alternative to chemical insecticidal. So in this study, fumigant toxicity of Petroselinum crispum L. (Apiaceae) plant oil on the abovementioned adult pest was investigated. Dry seeds were ground and subjected to hydrodistillation using a modified Clevenger-type apparatus and the resulting oil contained myristicin (42.65%), β-phellandrene (21.83%), p-1,3,8-menthatriene (9.97%), and β-myrcene (4.25%). All bioassay tests were conducted at 27±2°C, 65±5% relative humidity (RH) and at a photoperiod of 16 : 8 h (light : dark). This research was performed in a completely randomised design with six treatments (five different concentrations of essential oils plus the control). Each concentration included three replicates and each replicate consisted of 20 adult pests. The results showed that the aforementioned essential oil showed significant mortality of adults 24 h after exposure. The value LC50 of the mentioned plant oil on T. vaporariorum was 2.41 μl/l air. And mortality percentage showed higher sensitivity of T. vaporariorum against the application of the essential oil. The value LT50 estimated for T. vaporariorum in a concentration of 2.41 μl/l air was 8.17 h. The fumigant toxicity of this essential oil had an ordered relationship with the concentration and time exposure. The results of this research showed that the mentioned plant oil had appropriate insecticidal effects on these greenhouse pests. The findings showed that P. crispum oil had a high impact on the above-mentioned pest, and its use is suggested because of its high potential fumigant toxicity. The oil of P. crispum may be used in integrated pest management programmes in greenhouses.

Lethal Time

Essential oils of aromatic plants with insecticidal properties are nowadays considered as alternative insecticides to protect cultures from attack by insect pest. The aims of the present work were to evaluate the toxicity of the essential oils vapors of two aromatic plants ( Lippia multiflora Mold. and Aframomum latifolium K. Schum) against Bemisia tabaci and to characterize their chemical composition. The highest fumigant toxicity against B. tabaci adults was observed with the L. multiflora oil: by exposure to 0.4 μL/L air, the lethal time inducing 90% mortality (LT90) was below 2 hours for this essential oil whereas it reached 15 h in the case of the A. latifolium oil. Both oils were analyzed by GC-FID and GC-MS on two capillary columns. The oil of L. multiflora contained a majority of oxygenated terpenoids mainly represented by the two acyclic components linalool (46.6%) and ( E)-nerolidol (16.5%); the oil of A. latifolium was dominated by hydrocarbonated terpenoids among them β-pinene (51.6%) and β-caryophyllene (12.3%) were the two major components.
