“…Similar results on acute toxicity of Piper species on lepidopterans pest have been reported, for instance Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) -pest in maize (Murillo et al, 2014), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) -pest in tomato (Brito et al, 2015), Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae) -pest in sugarcane (Debonsi et al, 2008). In this perspective, our results indicate the potential of botanical insecticides in provide new molecules and likely new modes of action for pest management.…”

Plant essential oils have been recognized as important natural resources for bioprospection of new insecticides. Here, we provided a chemical analysis and assessing the toxicity of the essential oil of Piper aduncum L. (Piperaceae) against Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) a cosmopolite and key pest in agricultural systems. The essential oil was obtained from the leaves of P. aduncum via hydrodistillation. Subsequently, acute mortality bioassays with two modes of exposure (ingestion and topical methods) were conducted to assess the lethal effects. The chromatograph analysis of P. aduncum essential oil indicated myristicin, isomyristicin, asaricim, dillapiole and isocroweacin the compounds more abundant. The acute toxicity bioassays exhibited concentration-dependent to mortality of larvae of first and third instar of H. armigera, when exposure by ingestion or topical application to Piper essential oil, with highlight to reduction in survival in 1st instar larvae. The median lethal time (LT 50) when larvae were treated by ingestion was of LT 50 < 14.20 days (first instar) and LT 50 = 16.89 days (third instar). Whereas to larvae treated by topical method the median lethal time was of LT 50 < 14.68 days (first instar) and LT 50 < 10.73 days (third instar), which demonstrate a drastic reduction in survival of insect, when contrasted to control. In summary, our results highlight toxicity of P. aduncum essential oil against H. armigera and provide more information on plant-compounds that can be use in bioprospection of new insecticide molecules to pest management.

“…Performance assessment of these novel insecticides requires observations and experimental designs that encompass more than just simple assessment of knockdown effect. DoseÐresponse evaluations of insecticides conducted under controlled conditions typically involve application of known droplet doses onto certain body parts of individual insects as a topical application to assess mortality over time, levels of insecticide resistance, or to study insecticide mode of action (Young et al 2003, Nansen and Phillips 2004, Debonsi et al 2009). Studies involving such topical applications are important, but they do not incorporate variables associated with the likelihood of insects actually acquiring a lethal dose.…”

Uniform and controlled applications of insecticides constitute a fundamental aspect of applied research on performance of insecticides. We describe and evaluate a spraying device made from an artist airbrush and a soda bottle, the "bottle sprayer," which can be used to apply insecticide formulations both under laboratory and field conditions. Using the bottle sprayer in conjunction with quantitative behavioral analysis, it was shown that (1) miticides can significantly affect movement patterns and (2) it is possible to quantify mite repellency to miticides. The combination of controlled sprays to portions of trial arenas and quantification of behavioral responses by individual spider mites may be used to address a wide range of applied questions related to spider mite ecology. We used the bottle sprayer to apply water on water-sensitive cards and used simple image analysis techniques to correlate average reflectance per pixels (quadratic reflectance in blue color band) with water dose applied. Consequently, we were able to propose a method to quantify dose applied based on average color on water-sensitive cards. The spray card analysis based on data generated with the bottle sprayer was used to interpret spray card data obtained from spray applications in a commercial potato, Solanum tuberosum L., field and to discuss the possibility of developing quality control procedures for insecticide applications in field crops.

-The objective of this work was to evaluate the bioactivity of ethanolic leaf extracts from four species of the genus Piper against the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) under laboratory conditions. The evaluated species were: P. amalago var. medium, P. glabratum, P. mikanianum, and P. mollicomum. In the initial screening assay (extract concentration of 2,000 mg L -1 ), all tested extracts caused significant larval mortality, particularly the extract of P. amalago var. medium; however, no extracts reduced the weight of the surviving larvae. The extract from P. amalago var. medium at the concentration of 1,011 mg L -1 caused a significant lengthening of the larval and pupal stages. The ethanolic leaf extract of P. amalago var. medium is promising for the control of T. absoluta larvae in tomato, since it exhibits acute toxicity toward these caterpillars at the concentration of 2,000 mg L -1 and affects the insect's development by reducing its survival and lengthening the larval and pupal stages.
