“…Generally it can be concluded that the response of A. aegypti to the test compounds depends entirely on the differential mode of action of these compounds and its effective concentrations (Nazni et al, 2005). Studies in this respect were carried out by several authors to determine the susceptibility levels of mosquito vectors to different bioinsecticides (Nathan et al, 2005;Marina et al, 2012;Kundu et al, 2013), IGRs (Batra et al, 2005;Saleh et al, 2013) and plant extracts (Vatandoost and Vaziri, 2004;Kumar et al, 2012;Tennyson et al, 2013) Table 3 shows the effect of combinations of the chemical insecticide actellic (pirimiphosmethyl) with the bacterial insecticide spinosad, the IGR dudim and the plant extract of neem on A. aegypti larvae. The combinations were applied at the LC 25 value of actellic (0.027 ppm) and values of LC 30 , LC 40 and LC 50 of spinosad (0.006, 0.0072 and 0.009 ppm, respectively) and IC 30 , IC 40 and IC 50 values of dudim (0.00016, 0.00025 and 0.00038 ppm, respectively) and neem extract (26, 30 and 35 ppm, respectively).…”

“…Variations in the level of potentiation among the test mixtures may reflect the differences in their mode of action and the sublethal concentrations tested. Similar trials were carried out by using different combinations of conventional and non-conventional insecticides against A. aegypti (Saleh et al, 1990;Darri et al, 2010;Poonia and Kaushik, 2013), Culex pipiens (Al-Ghamdi et al, 2008) and Anopheles sundaicus (Kumar et al, 2012). However, long term followup studies were needed to determine how the environmental conditions affect the larvicidal effectivess of such compounds when applied jointly for field control measures.…”

Laboratory trials were conducted to determine the larvicidal activity of the bacterial insecticides (spinosad and vectobac), the insect growth regulators, IGRs (sumilarv and dudim) and the plant extracts of neem (Azadirachta indica) and usher (Calotropis procera) against Aedes aegypti (L.). The toxicity curves showed that the bioinsecticide spinosad proved to be more effective than vectobac against A. aegypti larvae by about 11.1 times. Such a fact was highly pronounced on the basis of LC 50 values (concentration which to kill 50% of larvae) which were 0.009 ppm and 0.1 ppm, respectively. According to IC 50 values (concentration which to inhibit the emergence of 50 % of adults), the results indicated that mosquito larvae of A. aegypti were more susceptible to the IGR dudim (0.00038 ppm) than sumilarv (0.004 ppm) by about 10.5 folds. The plant extract of neem was also more effective against the present larvae than usher extract, with IC 50 of 35 ppm and 66 ppm, respectively. Taking coeffective factor (C.F.) into consideration, the results revealed that the chemical insecticide actellic (pirimiphos-methyl) in combinations with spinosad, dudim and neem extract against the present mosquito larvae produced different levels of potentiation reflected by the inhibition of adult formation.

“…In our studies, we found the methanol leaf extract of this plant effective against the larvae of Culex quinquefasciatus. Other researchers (Singh et al, 2005;Elimam et al, 2009;Kumar et al, 2012;Anjum et al, 2016) reported similar effects of Calotropis procera against Culex quinquefasciatus and other mosquito species. Despite the efficacy of Calotropis procera on vector species, there seems to be paucity of information on the selection pressure of this plant on vector species.…”

Mosquitoes constitute a serious Public Health menace, resulting in millions of death worldwide each year. Emergence of insecticide resistant strains of the mosquitoes poses a serious threat and hence calls for alternative control measures. This study assessed the larvicidal efficacy of the methanolic leaf extract of Calotropis procera against the 3rd instar larvae of Culex quinquefasciatus, after ten generations for 24 hours of exposure. Larvicidal activities of the leaf of the plant were studied on laboratory reared larvae of Culex quinquefasciatus at concentration ranges of 15 mg/L to 19 mg/L. The LC50 values were obtained from Probit analysis at 95% confidence limit (CL). Results of the study indicated that the LC50 values obtained from the parent generation (F0) to the tenth generation (F10) were; 15.79 mg/L, 16.58 mg/L, 17.29 mg/L, 18.07 mg/L, 18.95 mg/L, 19.99 mg/L, 20.65 mg/L, 21.18 mg/L, 22.80 mg/L, 25.16 mg/L and 32.98 mg/L respectively at 24hours. A higher efficacy of activity was exhibited by the extract at the parent generation (F0) with lowest LC50 of 15.97 mg/L at 24h. The results of this research therefore underscore the efficacy of the plant and further suggest the use of the leaf extracts of Calotropis procera in the control of mosquito vectors and indirectly to the diseases they vectored.

Background: Mosquitoes are an important public health concern as they spread life-threatening diseases such as malaria, filaria, Japanese encephalitis, dengue fever, chikungunya, and yellow fever. In the last decades, synthetic insecticides were extensively used for the control of these vector-borne diseases but it also reported the detrimental side-effects in human beings and pet animals. To overcome the side effects, plants-derived secondary metabolites were screened and tested for insecticidal properties. The present study deals with the insecticidal activity of chloroform and methanol extracts of Swertia celiata leaves against Culex quenquifasciatus, Aedes aegypti, and Anopheles stephensi larvae.Method: The S. celiata leaves were subjected to chloroform and methanol with 1:3 (Weight/ Volume) ratio and the extracted solvent was dried using rotary vacuum evaporator. The larvicidal activity of the extract was tested using WHO method and LC 50 and LC 90 were evaluated by probit analysis. Results:The LC 50 value of chloroform extract of S. celiata was found to be 65.288, 67.406 and 71.608 ppm whereas LC 90 was 184. 721, 186.582 and 192.497 ppm against C. quinquefasciatus, Ae. aegypti and A. stephensi, respectively. The methanolic extract was also found potent; LC 50 was 91.503, 101.574 and 99.104 ppm whereas LC 90 was 230.823, 271.927 and 234.257 ppm against C. quinquefasciatus, Ae. aegypti and A. stephensi, respectively. Both chloroform and methanol extract were found significantly lethal to the tested mosquito vectors. Conclusion:Taken results together, chloroform extract showed higher toxicity as compared to methanolic extract against all the tested species. The study clearly revealed that S. ciliata extract or bioactive compounds can be used as an alternative to synthetic insecticides.
