BackgroundThe larvicidal efficacy of the naturally derived insecticide spinosad, for control of immature stages of Anopheles albimanus and associated culicids, was compared to that of synthetic and biological larvicides. Effects on non-target insects were also determined.MethodsA field trial was performed in replicated temporary pools during the rainy season, in southern Mexico. Pools were treated with 10 ppm a.i. spinosad (Tracer 480SC), Bti granules applied at 2 kg/ha (VectoBac WDG, ABG-6511), and 100 ml/ha temephos (50 EC), or an untreated control. Numbers of immature mosquitoes, and aquatic insects in pools were monitored for 20 weeks.ResultsSamples of immature mosquitoes comprised approximately 10% An. albimanus, 70% Culex spp. (mostly Cx. melanoconion and Cx. coronator) and 20% Uranotaenia lowii. The most effective larvicides were spinosad and temephos that eliminated An. albimanus in 16 out of 20 post-treatment samples, or 9 weeks of continuous control of immature stages, respectively. These larvicides resulted in 15 and 5 weeks of elimination of Culex spp., respectively, or 20 and 4 weeks of continuous elimination of U. lowii, respectively. Bti treatment provided little consistent control. Aquatic insects were recorded comprising 3 orders, 20 families, 40 genera and 44 species. Shannon diversity index values (H’) for aquatic insects were highest in the control (0.997) and Bti (0.974) treatments, intermediate in the spinosad treatment (0.638) and lowest in the temephos treatment (0.520). Severely affected non-target insects in the spinosad and temephos treated pools were predatory Coleoptera, Hemiptera and Odonata, which in the case of spinosad was likely due to the high concentration applied. Bti had little effect on aquatic insects.ConclusionsThe spinosad treatment retained larvicidal activity for markedly longer than expected. Spinosad is likely to be an effective tool for control of anopheline and other pool-breeding mosquitoes in tropical regions. Non-target effects of spinosad on aquatic insects merit further study, but were likely related to the concentration of the product used.

“…This insecticide is largely used in agriculture to control insects and mites. Some publications report the activity of the product on mosquitoes (Cetin et al, 2005), Musca domestica (Kristensen et al, 2004) and tsetse fly (De Deken et al, 2004). Two publications report the efficacy of the product on Ctenocephalides felis when administered monthly at a mean dose of 30 mg/kg (Snyder et al, 2007;Roberston-Plouch et al, 2008) The purpose of this study was to determine the duration of efficacy of a new formulation (spinosad tablets, ComfortisTM ® , Lilly Elanco) in the control of experimental infestations of adult fleas Ctenocephalides canis (Siphonaptera: Pulicidae) (Curtis, 1826) when administered once orally to Beagle dogs at the Laboratory recommended dosage (over 30 mg/kg).…”

Summary :A controlled clinical trial was performed to determine the duration of efficacy of a new oral insecticide formulation of spinosad for the control of experimentally induced Ctenocephalides canis infestations in dogs. Twelve Beagle dogs (two groups of six) were used in the study. Dogs in the treated group received spinosad tablets per os on D0 at the commercial dosage. All dogs were infested with 100 fleas on 7, 14, 21, 28 and 35. The dogs were combed four hours after each infestation and fleas were counted and replaced on the coat. 24 hours after each infestation fleas were combed, counted and removed. The efficacy of the formulation was calculated four and 24 hours after the treatment and then four and 24 hours after each new infestation. The mean number of fleas on the control dogs was respectively between 65.1 and 83.3 at four hour counts and between 58.3 and 75.3 at 24 hour counts. The product was well tolerated. The treatment controlled the fleas already present on the skin with 81 % efficacy at four hours and 100 % efficacy at 24 hours. For the weekly infestations, the speed of action of the product was high: at four hours the efficacy was 100 % at D7, 96 % at D14, 74 % at D21, 42 % at D28, 12.90 % at D35 and 12.8 % at D42. The efficacy evaluated 24 hours after each infestation was approximately 100 % during three weeks then 90 % at D39, 81.4 % at D36 and 80.4 % at D43. A single dose of the new spinosad tablet formulation should control flea populations in dogs for four weeks as indicated in the claim (evaluation performed at 48 h for the registration). Spinosad tablet is the first product administered per os which acts so long and so quickly against adult fleas. Résumé

The present study was carried out to establish the properties of Carica papaya leaf extract and bacterial insecticide, spinosad on larvicidal and pupicidal activity against the chikungunya vector, Aedes aegypti. The medicinal plants were collected from the area around Bharathiar University, Coimbatore, India. C. papaya leaf was washed with tap water and shade-dried at room temperature. An electrical blender powdered the dried plant materials (leaves). The powder (500 g) of the leaf was extracted with 1.5 l of organic solvents of methanol for 8 h using a Soxhlet apparatus and then filtered. The crude leaf extracts were evaporated to dryness in a rotary vacuum evaporator. The plant extract showed larvicidal and pupicidal effects after 24 h of exposure; however, the highest larval and pupal mortality was found in the leaf extract of methanol C. papaya against the first- to fourth-instar larvae and pupae of values LC(50) = I instar was 51.76 ppm, II instar was 61.87 ppm, III instar was 74.07 ppm, and IV instar was 82.18 ppm, and pupae was 440.65 ppm, respectively, and bacterial insecticide, spinosad against the first to fourth instar larvae and pupae of values LC(50) = I instar was 51.76 ppm, II instar was 61.87 ppm, III instar was 74.07 ppm, and IV instar was 82.18 ppm, and pupae was 93.44 ppm, respectively. Moreover, combined treatment of values of LC(50) = I instar was 55.77 ppm, II instar was 65.77 ppm, III instar was 76.36 ppm, and IV instar was 92.78 ppm, and pupae was 107.62 ppm, respectively. No mortality was observed in the control. The results that the leaves extract of C. papaya and bacterial insecticide, Spinosad is promising as good larvicidal and pupicidal properties of against chikungunya vector, A. aegypti. This is an ideal eco-friendly approach for the control of chikungunya vector, A. aegypti as target species of vector control programs.
