It is also important to point out that studies assessing the effects of protease inhibitors on the development of this multiple‐disease vector are scarce …”

“…Recently, Ragavendran and his group studied the Penicillium daleae mycelium metabolite treated with Artemia nauplii and its showed morphological changes in body structures (i.e., intestine enlargement, eye formation, outer shell malformations and loss of antennae) [59]. The study done in Brazil reported the bioassays of the isolates and combinations of compounds from endophytic fungus [83]. Likewise, Diana et al performed the Fusarium isolates (No: 24) showed various levels of toxicity on the brine shrimp, due to the presence of other toxins such as fusaproliferin and beauvericin compounds [84].…”

Background Mosquitoes biolarvicides remain the most important method for mosquito control. The previous studies have shown Aspergillus sp. -expressed larvicidal properties against mosquito species. The present study evaluated larvicidal and histopathological effect of an endophytic fungus Aspergillus tamarii isolated from theCactus stem ( Opuntia ficus-indica Mill) . Method The molecular identification of isolated A. tamarii was done by PCR amplification (5.8s rDNA) using a universal primer (ITS-1 and ITS-2). The secondary metabolites of A. tamarii was tested for larvicidal activity against Aedes aegypti and Culex quinquefasciatus . Larvicidal bioassay of different concentrations (- 100, 300, 500, 800 and 1000 μg/mL) isolated extracts were done according to the modified protocol. Each test included a set of control groups (i.e. DMSO and distilled water). The lethal concentrations (LC 50 and LC 90 ) were calculated by probit analysis. Experimental monitoring duration was 48 h. Results The ethyl acetate extract from A. tamarii fungus resulted - excellent mosquitocidal effect against Ae. aegypti and Cx. quinquefasciatus mosquitoes, with least LC 50 and LC 90 values. -After 48 h, the Ae. aegypti expressed better results (LC 50 = 29.10, 18.69, 16.76, 36.78 μg/mL and the LC 90 = 45.59, 27.66, 27.50, 54.00 μg/mL) followed by Cx. quinquefaciatus (LC 50 = 3.23, 24.99, 11.24, 10.95 μg/mL and the LC 90 = 8.37, 8.29, 21.36, 20.28 μg/mL). The biochemical level of A. tamarii mycelium extract on both larvae was measured and the results shown a dose dependent activity on the level of AchE, α- and β-carboxylesterase assay. Gas Chromatography and Mass Spectroscopy (GC-MS) profile of A. tamarii extract reflected three compounds i.e. preg-4-en-3-one, 17. α-hydroxy-17. β-cyano- (7.39%), trans-3-undecene-1,5-diyne (45.77%) and pentane, 1,1,1,5-tetrachloro- (32.16%) which which might had attributed to larvae mortality. Conclusion The findings of - present study shows that the use of endophytic A. tamarii fungal metabolites for control of dengue and filariasis vectors is promising and needs a semifield and small scale filed trials.

Dengue é uma das arboviroses mais importante no mundo atualmente, cuja transmissão se dá pela picada do mosquito Aedes aegypti. O controle do vetor, com produtos biológicos ou químicos, ainda é a principal forma de controle, sendo os inseticidas uma importante ferramenta nos programas de manejo integrado. Porém, esta estratégia encontra-se ameaçada pela seleção de resistência, especialmente aos organofosforados. O objetivo com o presente trabalho foi avaliar o status de susceptibilidade/resistência de populações de Ae. aegypti ao organofosforado Temephos® em dois municípios onde ocorre uso contínuo desse inseticida. Utilizou-se as concentrações diagnóstico 0,008 e 0,012 mg L-1 como preconizado, respectivamente, pela Superintendência de Controle de Endemias do Estado de São Paulo (SUCEN) e pela Organização Mundial da Saúde (OMS). Os resultados apresentaram percentual de mortalidade abaixo de 80% nas duas concentrações avaliadas, demonstrando resistência das populações ao inseticida. Este fato aponta para a necessidade de monitoramento da resistência nas populações de Ae. aegypti da região.
