“…Thus, the use of this botanical product would promote the management of both species. The bioactivity of plants is attributed to the several secondary compounds, mostly the volatile compounds that are present with their own diversity of structures (ISMAN, 2006;MORGAN, 2009). The repellent effect of these botanical species to the insect is probably caused by the content of these compounds in the plant structures used in the current study.…”

“…The repellent effect of these botanical species to the insect is probably caused by the content of these compounds in the plant structures used in the current study. These insecticide properties are attributed to several chemical compounds, specially to the active compound azadirachtin tetranotriterpenóide (MORGAN, 2009). With regard to R. graveolens, its aerial structure has more than 120 compounds described and related to different classes, such as acridone alkaloids, coumarin, essential oils, and flavonoids (OLIVA et al, 2003).…”

-This study aimed to evaluate the insecticidal activity of eight botanical species in the behavior and biological development of Zabrotes subfasciatus (Coleoptera: Chrysomelidae: Bruchinae) under laboratory conditions. The botanical species were applied on bean grains (Phaseolus vulgaris Linnaeus) directly as powder or indirectly within TNT bags. Three laboratory assays were performed. First, a repellent activity test was performed by exposing twenty couples of Z. subfasciatus adults in a choice-test arena. Second, a mortality test was performed for seven days after infestation. Finally, the oviposition and emergency rates of adults (%) and the development from egg to adult (in days) were evaluated in seven couples (males and females) for seven days inside of a vial containing 0.3g of the powder from each botanical species and 10 g of bean grains (3% w.w -1 ). The study was conducted in a completely randomized design, and the treatments were arranged as a factorial design (2 x 9) with two factors (factor 1= powder and TNT bag application forms and factor 2= eight botanical species and control) with eight replications. The powder application form was more efficient in controlling Z. subfasciatus. Azadirachta indica (powder application), Ruta graveolens (powder application), and Piper aduncum (TNT bag) reduced the infestation of adults. The species A. inidica, Piper tuberculatum, Trichilia catigua, Pfaffia glomerata, R. graveolens, and Mentha pulegium inhibited the oviposition of the insects regardless of the formulation applied. R. graveolens (powder application) caused 100% of mortality. The powder application of R. graveolens and M. pulegium reduced egg viability and insect emergence; therefore, they are very promising alternatives to control Z. subfasciatus in stored grains.Keywords: Bruchinae.

INSETICIDAS VEGETAIS COMO ALTERNATIVA PARA O MANEJO DO CARUNCHO-DO-FEIJÃORESUMO -O objetivo do trabalho foi avaliar o efeito de pós de oito espécies botânicas, misturados aos grãos de feijão, Phaseolus vulgaris (Fabaceae), ou em sachês, sobre os aspectos comportamentais e de desenvolvimento biológico de Zabrotes subfasciatus (Coleoptera: Chrysomelidae: Bruchinae) em laboratório. Três ensaios foram realizados. Primeiro, a repelência de adultos de Z. subfasciatus pelas espécies vegetais foi avaliada com 20 casais em teste com chance de escolha. Segundo, a mortalidade de adultos foi avaliada, diariamente, até o sétimo dia após a infestação. Terceiro, sete casais foram mantidos por sete dias em recipientes contendo 0,3 g de pó de cada espécie vegetal e 10 g de grãos de feijão (3% p.p -1 ) para avaliação dos parâmetros oviposição, emergência de adultos (%) e período de desenvolvimento ovo-adulto (dias) de Z. subfasciatus. Os ensaios seguiram arranjo fatorial 2 x 9 (fator 1 = formas de aplicação pó e sachê; fator 2 = oito espécies vegetais e testemunha) em delineamento inteiramente casualizado com oito repetições. A forma de pó foi mais eficiente no controle de Z. subfasciatus.

Unusually versatile plant genus Azadirachta with many useful and so far incompletely exploited properties for agriculture, medicine and industry

Azadirachta indica (Indian Neem), A. siamensis (Thai Neem) and A. excelsa (Marrango, Philippinean/Malaysian Neem) belong to the Mahogany family and are endemic to the Indian subcontinent, with subsequent anthropogenic expansion to South-East Asia, but also into all tropical and subtropical areas of the globe. Traditional neem uses in stored product protection and medicine in India are well established for thousands of years. Recently, modern methods of analytical, organic and biochemistry could explain biochemical mechanisms of action. This was followed by greatly expanded insect management practices based on the useful properties of neem and neem oil. These natural products can serve as insect phago-deterrents and fitness reducing agents against pest insects, but also against bacterial, fungal and virus diseases of plants, domestic animals and humans. Neem products, in concert with pheromones, are the general agents of choice if all other control measures for various reasons fail.

“…In the recent past, chemical constituents of Neem seeds have been intensively explored since they have proved to be an excellent source of a wide variety of chemicals useful to the management of pestiferous insects . More than 500 insect pest species are listed as sensitive to Neem seed extracts (Morgan, 2009). These biological proprieties are caused mainly by terpenoid compounds several papers are reported to contain bitter substances, popularly known as limonoids (Figure 1) (Luo et al, 1999;Siddiqui et al, 1999;Siddiqui et al, 2001).…”
