“…This analysis suggests that homemade insecticides based on all 12 selected botanicals may or may not provide, under different circumstances, control of arthropod pests. Homemade botanical insecticides based on other botanicals have provided control of pests, such as Mexican tea, Dysphania ambrosioides L. (Asterales: Asteraceae) (Mazzonetto et al 2013;Mkenda et al 2015b;Pamela Nuñez et al 2010;Paul et al 2009;Tapondjou et al 2003) or billygoat weed, Ageratum conyzoides (L.) Mosyakin & Clements (Caryophyllales: Amaranthaceae) (Amoabeng et al 2013(Amoabeng et al , 2014Kar et al 2008;Onunkun 2012;Singh et al 2013). However, this review was conditioned by the availability of literature.…”

Homemade botanical insecticides are widely used by subsistence and transitional farmers in low-income countries. Their use is often driven by the limited availability or cost of commercial pesticides. Homemade botanical insecticides are often recommended by agricultural extension services and some development organizations. However, this could be questioned because scientific evidence of their efficacy and safety may not be available or accessible. Although botanicals with insecticidal properties have been widely studied, a synthesis focusing specifically on homemade preparations used in realistic field or storage conditions is missing. In this paper, we review efficacy assessments of botanicals used to prepare homemade insecticides. This covers twelve botanicals recommended by national extension partners in 20 countries within the global agricultural Plantwise program. These are as follows: garlic (Allium sativum), neem (Azadirachta indica), chili pepper (Capsicum spp.), Siam weed (Chromolaena odorata), mother of cocoa (Gliricidia sepium), chinaberry (Melia azedarach), moringa (Moringa oleifera), tobacco (Nicotiana tabacum), clove basil (Ocimum gratissimum), tephrosia (Tephrosia vogelii), tree marigold (Tithonia diversifolia), and bitter leaf (Vernonia amygdalina). This review shows that (1) all the selected botanicals contain active ingredients with insecticidal, antifeedant, or repellent properties, and (2) homemade insecticides based on all the selected botanicals have been used with some success to control pests or prevent damage, although efficacy was variable and often lower than the positive controls (synthetic pesticides). Factors affecting the efficacy of homemade botanical insecticide include variation in active ingredient content and concentration in plant material, as well as variation in the preparation process. In conclusion, there is some evidence that homemade botanical insecticides could contribute to reducing losses in food production. Since further research is needed to better understand their variable efficacy and potential health and environmental risks, those who promote the use of homemade botanical insecticides should also communicate those "unknowns" to the farmers who use such products.

Sitophilus zeamais Motschulsky es a nivel mundial una de las principales plagas de los cereales almacenados y su control se basa en insecticidas sintéticos, pero su uso irracional ha provocado contaminación del ambiente y resistencia. Los aceites esenciales han mostrado efecto insecticida de contacto y fumigante por lo que podrían constituir una alternativa a los compuestos sintéticos. Por este motivo se evaluaron, en condiciones de laboratorio, las propiedades insecticidas del aceite esencial de Chenopodium ambrosioides L. contra adultos de S. zeamais. Las variables evaluadas fueron toxicidad por contacto y fumigación, y actividad antialimentaria y repelente. La mortalidad por contacto no superó el 30% en todos los tratamientos evaluados. La mayor reducción de la F 1 se observó en el tratamiento de 4,0% con 41,3% de emergencia (58,7% de inhibición). La pérdida de peso de los granos fue menor a 9,0% y la germinación del maíz no se vio afectada. Todos los tratamientos mostraron actividad fumigante y las concentraciones iguales o superiores a 0,5% tuvieron efecto repelente y antialimentario. Se concluye que el aceite esencial de Ch. ambrosioides presenta potencial para el control de S. zeamais.

Plutella xylostella L. is one of the main agents to cause damages to plants of Brassica genus, provoking negative impacts in cultures. The use of botanical extracts in plants protection has been related in literature, however, their use in the species analyzed in this study is not yet reported. We assessed the effect of aqueous and methanolic extracts of the species: Schinus terebinthifolius Raddi ( -branco), occuring in the state of Mato Grosso do Sul and whose feeding preference of P. xylostella larvae of 3rd instar. We intend to answer the following questions: (1) Are the plant species analyzed fagodeterrentes? (2) what type of extract produces the least food preferrence? To answer these questions, we treated cabbage disks with aqueous extracts stored in a refrigerator in periods of 0, 7, 14 and 21 days and the methanolic extracts were treated at concentrations of 0.5 mg/mL, 1.0 mg/ mL, 2.0mg/mL. The aqueous and methanolic extracts of T. silvatica presented the lowest values of feeding preference, 0.113 and 0.06, respectively, compared to other extracts.
