“…Further, the mortality of Q biotype at 37°C is 27%, whereas that of B biotype is 61% (Mahadav et al, 2009). B. tabaci cannot survive chilled winter in northern China (Lin et al, 2007). Our results show that the thermal tolerance of adult B. tabaci was significantly reduced by TYLCV acquisition.…”

“…Regarding vectors, thermal stress may have significant potential for modifying a vector's capability to mediate virus transmission. The heat stress response in B. tabaci has been studied in the context of survival and reproduction, gender, and biotype at the ecological and molecular levels (Wolfe et al, 1999;Salvucci et al, 2000;Lin et al, 2007;Cui et al, 2008;Lü and Wan, 2008;Mahadav et al, 2009;Wang et al, 2011). However, there have been no studies on the effects of thermal stress on the ability of B. tabaci or even other species to mediate virus transmission.…”

“…Although B-biotype B. tabaci has been protected from the extreme low temperatures of winter under greenhouse conditions, it can be subjected to low temperatures in open Þelds in spring or in autumn. Low temperature can cause cessation of oviposition of adults and the mortality of the immature stages (Ohnesorge et al 1981, Sharaf 1982, Simmons and Elsey 1995, Lin et al 2007). B. tabaci has no speciÞc cold tolerance stage in its life cycle.…”

Rapid Cold Hardening and Expression of Heat Shock Protein Genes in the B-BiotypeBemisia tabaci

et al. 2011

This paper describes the rapid cold hardening processes of the sweetpotato whitefly, Bemisia tabaci (Gennadius). It was found that all developmental stages of B. tabaci have the capacity of rapid cold hardening and the length of time required to induce maximal cold hardiness at 0 °C varies with stage. There was only 18.3% survival when adult whiteflies were transferred directly from 26 °C to -8.5 °C for 2 h. However, exposure to 0 °C for 1 h before transfer to -8.5 °C increased the survival to 81.2%. The whiteflies show "prefreeze" mortality when they were exposed to temperatures above the supercooling point (SCP), although the range of SCP of whiteflies is -26 °C to -29 °C. The rapid cold hardening had no effect on SCP and reduced the lower lethal temperature of adults from -9 °C to -11 °C. Rapid cold-hardened adults had a similar lifespan as the control group but deposited fewer eggs than nonhardened individuals. The expression profiles during cold hardening and recovery from this process revealed that HSP90 did not respond to cold stress. However, HSP70 and HSP20 were significantly induced by cold with different temporal expression patterns. These results suggest that the rapid cold hardening response is possibly advantageous to whiteflies that are often exposed to drastic temperature fluctuations in spring or autumn in northern China, and the expression of HSP70 and HSP20 may be associated with the cold tolerance of B. tabaci.

“…Among the insect pests, sweet potato whitefly (Bemisia tabaci Genn.) reported as pest of tobacco in 1889 (Lin et al, 2007) is a major threat worldwide (Kakimoto et al, 2007;Bayhan et al, 2006) feeding on vegetables, fruit crops (Naveed et al, 2007;Chaudhuri et al, 2001) and pulses from 86 botanical families (Salas and Medoza, 1995). Adults and nymphs are damaging stages and generally found resting underside of the leaves.…”

“…According to Lin et al (2007), despite major advances having been made in understanding the biology and behavior of B. tabaci and in developing pest-management systems (Gerling and Mayer, 1996;Naranjo, 2001), whitefly still remains a major threat for commercial cultivation and this may be attributed to intensive use of pesticides (Bonato et al, 2007). Characteristic features like high natality rate, broad host range, ability to adapt to new hosts and ability to develop resistance to insecticides etc., are few reasons behind the geographic expansion of whitefly and its importance (Basit et al, 2012).…”

Ecology of whitefly Bemisia tabaci Genn., has been studied extensively in the recent past and a varying response was observed on different host plants. The degree of this variation is because of type of host plant combination. The present investigation was conducted to find out the comparative age specific survival, mortality and life table parameters in presence of four major fruit bearing vegetables that is brinjal (Solanum melongena L.), chili (Capsicum annuum L.), tomato (Lycopersicon esculentum Mill.) and okra (Abelmoschus esculentus (L.) Moench), under laboratory conditions (26±3°C, RH: 75±5% and photophase: 14 h). The maximum survival and minimum mortality was observed on brinjal, while chili has been documented with reciprocity. Among the host plants, on which whitefly was reared, brinjal has shown superiority, documenting least mortality and shorter development of immature stages of whitefly. Least generation time (23.67±0.97 days) was observed on brinjal and maximum time was consumed on chili (33.57±1.10 days). Similarly, the highest intrinsic rate of increase (r m ) was recorded on brinjal followed by tomato and the smallest r m was observed on chili. A significant difference in net reproductive rate (Ro) was perceptible, being highest on tomato (89.50±2.13 females/female). However; corresponding potential fecundity and maximum mean egg laying was received on brinjal. Fastest doubling time was also recorded on brinjal (8.41±0.02 days) followed by tomato (10.87±0.03 days) while maximum doubling time was witnessed on chili (14.01±0.05 days). The highest annual rate of increase (ARI), 1.27±0.02x10 10 of individuals per year was found on brinjal and lowest on chili. The host preference of whitefly on the basis of present investigations, can be arranged in the following order brinjal>tomato>okra>chili.
