“…This product presented a high toxicity against many orders of insects such as Lepidoptera pests (Toews & Subramanyam 2003) and Coleoptera (Galvan et al 2005) and could cause the mortality of the endoparasitoid larvae of Hyposoterdi dymator (Schneider et al 2004). Spinosad also has larvicidal activity on mosquito larvae (Prabhu et al 2011;Arjunan et al 2014). As shown by the present results this product exhibits a high level of toxicological activity against newly emerged females of B. orientalis.…”

“…The mean development time was 11.403 ± 1.04 days, which was comparable to the other three species examined in this study (Table 2 ). The fastest observed development rate was 2.703 days at 32 °C [ 84 ], and the slowest was 31.25 days at 15 °C [ 89 ]. Though most studies reported a linear relationship between temperature and development, this is only true within the survivable temperature range.…”

“…Though most studies reported a linear relationship between temperature and development, this is only true within the survivable temperature range. The minimum threshold for development for this species appears to be between 11 and 18 °C [ 37 , 84 , 86 , 93 , 114 ]. The maximum threshold is more complex; it appears to be between 34 and 38 °C [ 84 , 86 , 93 , 114 ].…”

Background Mosquitoes in the genus Culex are primary vectors in the US for West Nile virus (WNV) and other arboviruses. Climatic drivers such as temperature have differential effects on species-specific changes in mosquito range, distribution, and abundance, posing challenges for population modeling, disease forecasting, and subsequent public health decisions. Understanding these differences in underlying biological dynamics is crucial in the face of climate change. Methods We collected empirical data on thermal response for immature development rate, egg viability, oviposition, survival to adulthood, and adult lifespan for Culex pipiens, Cx. quinquefasciatus, Cx. tarsalis, and Cx. restuans from existing literature according to the PRISMA scoping review guidelines. Results We observed linear relationships with temperature for development rate and lifespan, and nonlinear relationships for survival and egg viability, with underlying variation between species. Optimal ranges and critical minima and maxima also appeared varied. To illustrate how model output can change with experimental input data from individual Culex species, we applied a modified equation for temperature-dependent mosquito type reproduction number for endemic spread of WNV among mosquitoes and observed different effects. Conclusions Current models often input theoretical parameters estimated from a single vector species; we show the need to implement the real-world heterogeneity in thermal response between species and present a useful data resource for researchers working toward that goal.

“…Maximum temperature in our study helps in the epidemic of bluetongue because temperature also significantly influences the activity rates of adult insects. The scientific reason behind is adult culicoides are more active than on cooler days and their reproduction will be inhibited by low temperature [17]. However, BTV has a strong environmental resistance and will not lose its infectivity in seven days under 56 0 C [18].…”

This research correlates the effect of climatic factors on bluetongue epidemiology in sheep of delta districts in Tamilnadu based on merteriological data collected from 2014 to 2016. There were a total of eighty two villages of delta districts were affected with Blue tongue virus (BTV). We used multiple linear regression analysis to assess the effect of climatic factors on the prevalence of bluetongue. Our results showed that maximum temperature, rain fall and relative humidity positively correlates with the number of BTV epidemic in sheep flocks. These findings suggest that the risk of BTV infections in sheep increased in warm and humid environments. Moreover, climatic factors can be used to forecast the possible epidemic in this area and other regions characterized by similar climatic conditions.
