“…(hislopii: Euphorbiaceae) effect post embryonic development of Megaselia sclaleris (phoridae). Latexes from Asclepias humistrata (sandhill milkweed) [26], Calotropis procera and Ficus racemosa have shown larvicidal activity [27], Parahancornia ampa (Apocynaceae), latex shows effect on post embryonic development of blowfly Chrysomya megacephala (Diptera: Calliphoridae) [28]. Similar anti-termite potential was observed in (Tung tree) Aleurites fordii extracts against Reticuletermes flavipes [29].…”

In the present investigation various bioassays were conducted to evaluate the anti-termite efficacy of plant latex based formulations to control population of Indian white termite in subtropical soil. Results reveal that crude latex, its fractions and combinatorial fractions have shown very high toxicity against O. obesus. The LD 50 values for different latex fractions of 24 h were in a range of 5.0 -17.613 μg/mg while combined mixtures of Calotropis procera have shown synergistic activity against termites and caused comparably high mortality with LD 50 1.987 -6.016 μg/mg. The mortality rate was found dose and time dependent as it was found to be increased with an increase in dose and exposure period. In olfactometry tests, C. procera latex solvent fractions have shown significant repellency at a very low dose 0.010 -0.320 μg/mg. Interestingly, solvent fractions have significantly repelled large numbers of worker termites due to volatile action of active components of latex and different additives. ED 50 values obtained in crude latex were 0.121 μg/mg body weights while combinatorial formulations have shown ED 50 in between 0.015 -0.036 μg/mg. Statistical analysis of repelled and un-repelled termites gave a low Chi-square value (X 2 value = 0.890) which is an indicator of independence of repellent action in randomly selected termite groups. In field experiments pre-soaked cotton threads impregnated with Calotropis procera crude latex were tagged around tree trunks of Tectona grandis provided a wider protection against O. obesus. By employing these pre-coated threads, termite infestation and tunneling activity were significantly decreased (p < 0.05 and 0.01). When germinating crop plants were sprayed with various plant latex formulations, these have caused very high protective efficacy against termite infestation. It has significantly reduced crop losses up to 6.45%. There was a significant difference in infestation obtained in control and treatment groups (P < 0.05 and 0.01) which shows that Calotropis procera possesses enough anti-termite potential against Indian white termite, O. obesus population. If used these, formulations may also provide wide a range of control against other kinds of pests including house hold, medical and veterinary. However, Calotropis procera latex based formulations can be recommended for effective control of termites in high infestation areas by applying spray, or in form of poison baits or as fumigant in pure form.

“…Necrophagous Diptera are more suitable to pupate even when the final weight is below the average estimated for other species (MENDONÇA et al, 2011). According to Lomonaco & Germanos (2001), the increasing in the development period may be due to delays in obtaining the necessary weight for pupating (ROPER et al, 1996), due to the difficulties in obtaining food.…”

Essential oil of Cymbopogon citratus collected from Brazil and Cuba was tested to a chemical characterization and then was tested on the post-embryonic development of Musca domestica. The chemical composition analysis by GC-MS of the oils from Brazil/Cuba allowed the identification of 13 and 12 major constituents respectively; nine of them common to both. In the both oils, the main components were the isomers geranial and neral, which together form the compound citral. This corresponds to a total of 97.92%/Brazil and 97.69%/Cuba of the compounds identified. The monoterpene myrcene, observed only in the sample of Cuba, presented a large relative abundance (6.52%). The essential oil of C. citratus (Brazil/Cuba) was dissolved in DMSO and tested at concentrations of 5, 10, 25, 50, 75 and 100% and citral was prepared by mixing 16.8 mg with 960 µL DMSO. Both essential oils and monoterpene citral were applied topically to newly-hatched larvae (1µL/larva). The results showed a lethal concentration (LC50) of 4.25 and 3.24% for the Brazilian and Cuban essential oils, respectively. Mortalities of larval and newly-hatched larvae to adult periods were dose-dependent for the two both oils as for monoterpene citral, reaching 90%. Both essential oils and citral caused morphological changes in adult specimens.Keywords: Vector control, essential oil, house-fly, lemongrass, Cymbopogon citratus. ResumoO óleo essencial de Cymbopogon citratus, coletado no Brasil e em Cuba, foi caracterizado quimicamente e testado no desenvolvimento pós-embrionário de Musca domestica. A análise da composição química dos óleos essenciais (Brasil/Cuba), por Cromatografia Gasosa acoplada ao espectrômetro de massa (GC-EM), permitiu a identificação de 13 e 12 componentes principais, respectivamente; nove deles comuns aos dois. Em ambos os óleos, os principais componentes foram os isômeros geranial e neral, que, juntos, formam o composto citral. Esse corresponde a um total de 97,92%/Brasil e 97,69%/Cuba dos compostos identificados. O monoterpeno mirceno, observado na amostra cubana, apresentou grande abundância relativa (6,52%). O óleo de C. citratus (Brasil/Cuba) foi dissolvido em DMSO, obtendo-se as concentrações de 5, 10, 25, 75 e 100%; e o citral (16,8 mg) foi misturando com 960mL de DMSO. Tanto o óleo essencial como o monoterpeno citral foram aplicados topicamente nas neolarvas (1µL/larva). Os resultados mostraram uma concentração letal (CL50)

“…According to Mendonça et al (2011) used chemical insecticides for insect control are dangerous and can especially affect man, and other animals can pollute air, water and the food chain. However, some natural substances extracted from plants have been shown to have insect repellent properties, feeding deterrents, toxic components and developmental disruptors (Feinstein, 1952;Cabral et al, 2007a;Mendonça et al, 2011).…”
