The molluscicidal effect of nicotinanilide was evaluated and compared with niclosamide (2',5-dichloro-4'-nitrosalicylanilide, ethanolamide salt) against different stages of the freshwater snail Lymnaea luteola i.e., eggs, immature, young mature, and adults. Calculated values of lethal concentrations (LC50 and LC90) showed that both nicotinanilide and niclosamide as toxic against eggs, immature,...

Field resistance to Bacillus sphaericus was observed in a population of Culex quinquefasciatus in Kochi, India, exposed to 35 rounds of spraying with a formulation of B. sphaericus 1593 M over a 2-year period. Larvae from the sprayed area gave LC50 and LC90 values that were 146 and 180 times greater than corresponding values for a susceptible strain from an unsprayed locality. When the resistan...

AIM This research was conducted to evaluate the molluscicidal and mosquitocidal efficacy of silica nanoparticles in the eradication of the larvae and pupa of malaria and filariasis vector as well as vectors of rift-valley fever virus (Culex pipiens); Schistosoma mansoni vector and Biomphlaria alexandrina (snail and egg masses). MATERIALS AND METHODS Hydrophilic nanosilica particles (NSPs) wer...

Aedes aegypti is a vector mosquito of dengue haemorrhagic fever, chikungunya, yellow zika, filariasis and other viral infectious disease-causing pathogens. We tested ethanol extracts the six plant species viz., Cassia fistula, Curcuma amada, Manilkara zapota, Momordica charantia, Sansevieria trifasciata Solanum indicum at dosages 25, 50, 75 100% for their larvicidal effect against third instar ...

Due to the ability locate host plant over long distances, and direct indirect damage that are caused, Rhynchophorus palmarum L. (Coleoptera: Curculionidae) is considered a key pest of coconut crop. Therefore, objective this research was evaluate efficiency by contact insecticide thiamethoxam on adults R. palmarum, determining lethal concentrations (LC50 LC90), under laboratory conditions. One m...

Amaç: Bitkilerden elde edilen uçucu yağlar, geleneksel sentetik böcek öldürücülere çevre dostu alternatifler sağlayabilir. Bu çalışmada beş farklı esansiyel yağın (Thymus vulgaris, Piper nigrum, Syzygium aromaticum, Hypericum perforatum, Papaver somniferum) Musca domestica larvalarına karşı etkisinin değerlendirilmesi amaçlanmıştır. Yöntem: Her yağ çeşidinin üç dozu (% 1, % 3 ve 6) tekerrürlü o...

Mosquitoes are the carriers of severe and well-known illnesses such as malaria, arboviral encephalitis, dengue, chikungunya and yellow fever, which cause significant morbidity and mortality in humans and domestic animals around the world. Entomopathogenic fungal metabolites act as a mosquito control agent and are potential alternatives to chemical control because they can be innovative and more...

Ivermectin has potent systemic activity against numerous species of nematodes and arthropods, but there are some important species in these two groups, such as the cat flea, Ctenocephalides felis (Bouché), that appear to be refractory to it. In an effort to determine if the lack of systemic activity against C. felis is specific to ivermectin, or if it is a class-wide phenomenon, 20 avermectin d...

The bio-efficacy of Aloe vera leaf extract and bacterial insecticide, Bacillus sphaericus larvicidal activity was assessed against the first to fourth instars larvae of Aedes aegypti, under the laboratory conditions. The plant material was shade dried at room temperature and powdered coarsely. A. vera and B. sphaericus show varied degrees of larvicidal activity against various instars larvae of...

BACKGROUND & OBJECTIVES Screening of crude extracts of plants facilitates the establishment of highly effective extract for mosquito control. This practice should be preferred before in depth study of plant extracts rather than spending much efforts and energy in detailed examinations for practically ineffective extracts. In this study, leaf powders of four weed plants were used for the quick s...
