“…Identifying these synergist compounds within mixtures may lead to the development of more effective biocides as well as the use of smaller amounts of synthetic insecticides in the mixture to achieve satisfactory levels of efficacy. Indeed, joint action may well prolong the usefulness of synthetic insecticides that will eventually be unusable due to resistance [31]. Our earlier studies on Culex pipiens larvae with Nigella sativa seed extracts [32], volatile oil of Thymus capitatus [33], citrus peel oils [34], and different ethanolic plant extracts against larvae and adult stages of Anopheles pharoensis [35] have shown potentiating toxicity when mixed these botanicals with certain insecticides in pairs of combinations.…”

Following preliminary screening of 13 ethanolic plant extracts, belonging to 10 different families, a total of 11 extracts were subjected to detailed toxicity evaluation against the larval stage of the housefly, Musca domestica L. The larvicidal LC 50 values were < 100 ppm for Piper nigrum (50.1 ppm), Azadirachta indica (76.9 ppm), Conyza aegyptiaca (77.0 ppm) and Cichorium intybus (96.8 ppm); representing the highest potent extracts among the bioassayed candidates. Punica granatum extract exhibited the lowest toxicity (213.9 ppm). In comparison, commercial insecticides showed superior larvicidal toxicity; accounting to the following LC 50 values: 0.029, 0.03, 0.61 and 0.64 ppm for deltamethrin, methomyl, chlorpyrifos and flufenoxuron, respectively. Combining botanical extracts with insecticides, at equitoxic dosages (e.g., LC 25 values), induced potentiating effects for a 44 bioassayed mixtures against the housefly larvae. Moreover, mixing the insecticides at LC 0 (a concentration level causing no observed mortality) with the LC 50 of each of the plant extracts have resulted in 44 paired combinations. Mostly, the "synergistic factor; S.F." ranged between 1.6 -1.9; giving rise to high synergistic effects. Specifically, the synergistic effect was much pronounced for mixtures of the insecticide deltamethrin with different botanical extracts. Most of the tested toxicants induced different forms of developmental effects after exposure of 3 rd larval instars to sublethal concentrations (LC 25 ppm). Larvae treated with A. indica, Citrus aurantifolia, Eucalyptus globulus (leaves or fruits), P. granatum, Salix safsaf, Sonchus oleraceus, Zea mays, as well as the insecticides chlorpyrifos, deltamethrin and methomyl failed to develop into adult stages. Morphologically, there were different forms of pupal and adult abnormalities, where the treatments of P. granatum and S. oleraceus caused abnormal pupal size in addition to pupal-adult intermediate. In the resulted Musca domestica adults, the effects were seen as one-winged insects, small size, compressed body and abdomen elongation. Such deformations were attributed to treatments of C. intybus, C. aegyptiaca, Piper nigrum and the IGR flufenoxuron. The overall results of the present investigation reveal the broad-spectrum toxic properties of the tested plant extracts against Musca domestica larvae; which may encourage further research on housefly control in tropics using indigenous plants.

“…The aforementioned problems created awareness of the need for new insecticides for mosquito control which are ecofriendly and target specific (Sukurmar et al, 1991;Shaalan et al, 2005;Sharma and Srivastava, 2006). The screening of local medicinal plants for mosquito larvicidal activity may lead to their use in natural product-based mosquito abatement practices.…”

Introduction:In vitro bioassays were performed to access the larvicidal activity of crude extracts from the endophytic fungus Pestalotiopsis virgulata (Melanconiales, Amphisphaeriaceae) and the saprophytic fungus Pycnoporus sanguineus (Basidiomycetes, Polyporaceae) against the mosquitoes Aedes aegypti and Anopheles nuneztovari. Methods: The extracts were tested at concentrations of 100, 200, 300, 400 and 500ppm. Ethyl acetate mycelia (EAM) extracts and liquid culture media (LCM) from Pe. virgulata and Py. sanguineus were tested against third instar larvae of Ae. aegypti and An. nuneztovari. Results: The larvicidal activity of the EAM extracts from Pe. virgulata against Ae. aegypti had an LC 50 =101.8ppm, and the extract from the basidiomycete fungus Py. sanguineus had an LC 50 =156.8ppm against the Ae. aegypti larvae. The Pe. virgulata extract had an LC 50 =16.3ppm against the An. nuneztovari larvae, and the Py. sanguineus extract had an LC 50 =87.2ppm against these larvae. Conclusions: These results highlight the larvicidal effect of EAM extracts from the endophyte Pe. virgulata against the two larval mosquitoes tested. Thus, Pe. virgulata and Py. sanguineus have the potential for the production of bioactive substances against larvae of these two tropical disease vectors, with An. nuneztovari being more susceptible to these extracts.
