“…They believed that oviposition range of B. tabaci based on the temperature, host, plants and insect biotype was significantly variable and showed that the gross fecundity and fertility rates, gross hatch rate, and net fecundity and fertility rates were greater on rapeseed than on cotton. The developmental times of B biotype (22.28 d) reared on cotton in this study were nearly equal to those reared on cotton (23.6 d) and poinsettia (23.2 d) at about 25ºC (Bethke et al 1991) and on sweet pepper (21.5 d) at 26ºC (Muniz and Nombela 2001). The fecundity of B biotype reared on rapeseed (68 eggs) was higher than on cotton (51.2 eggs) (Bethke et al 1991) and less than on poinsettia (85.0 eggs) (Bethke et al 1991), tobacco (72.3 eggs) (Enkegaard 1993) at about 25ºC, and on alfalfa, broccoli, cantaloupe, cotton and zucchini (40.6 -70.6 eggs) at 27ºC (Yee and Toscano 1996).…”

(R 0 or NRR), intrinsic rates of increase (r m ), finite rate of increase (λ), doubling time (DT) and mean generation times (T c ).To obtain a better understanding of the biology of these biotypes, Stable age distribution (C x ) and some other aspects of life history related to their hosts were also studied. Based upon the results, both biotypes showed a greater reproduction capacity on rapeseed than on cotton. Thus, rapeseed was more suitable host than cotton for two biotypes and this was an important factor in host plant selection for optimizing the control strategies of these major pests.

The effect of temperature on the development of the predators Nephus includens (Kirsch) and N. bisignatus (Boheman) (Coleoptera: Coccinellidae), was studied. The development time of immature stages and the pre-oviposition period of adult females for the two predators was recorded at eight constant temperatures (10, 15, 20, 25, 30, 32.5, 35 and 37.5°C). The beetles were reared on eggs, nymphs and female adults of Planococcus citri (Risso) (Homoptera: Pseudococcidae) that had developed on squash (Cucurbita pepo) and on sour orange leaves (Citrus aurantium). Using the linear mode! for the biological cycle of N. includens on squash and on sour orange leaves, the developmental zeros (lower temperature thresholds) were estimated to be 10.9 and 11.0°C respectively and the thermal constants, 490.5 and 472.8 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 11.1 and II.2°C respectively and the upper thresholds 36.1 and 36.0 U C respectively. For the biological cycle of N. bisignatus, using the linear model, the lower thresholds were estimated to be 9.4°C on squash and 9.3°C on sour orange leaves and the thermal constants were 614.3 and 647.9 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 9.9 and 10.0"C respectively and the upper thresholds, 34.7 and 35.0"C respectively. The survival rate of N. includens instars at 10, 15, 20, 25, 30, 32.5, 35 and 37.5°C on squash and on sour orange leaves was respectively 0, 34.9, 63.2, 70.6, 63.3, 54.5, 19.8, 0, and 0, 32.2, 61.0, 68.0, 68.3, 56.6. 17.6, 0%. The survival rate of N. bisignatus instars at 10, 15, 20, 25, 30, 32.5 and 35°C on squash and on sour orange leaves was respectively, 0, 39.9, 61.1, 60.7, 47.2, 26.4, 0 and 0, 35.7, 65.7, 68.0, 44.2, 29.1, 0%. The results show that N. includens has a shorter biological cycle than N, bisignatus, whereas the latter species has lower temperature thresholds.

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 LC 50 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 LT 50 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.
