“…Coleoptera were the most represented, with 13 species in six families, encompassing mainly stored grain-feeding beetles [22,46,55–59,62–64,67–71,80], flea beetles [51,65,72] and a flower weevil [81]. …”

The physic nut shrub, Jatropha curcas (Euphorbiaceae), has been considered as a “miracle tree”, particularly as a source of alternate fuel. Various extracts of the plant have been reported to have insecticidal/acaricidal or molluscicidal/anthelminthic activities on vectors of medical or veterinary interest or on agricultural or non-agricultural pests. Among those extracts, the phorbol ester fraction from seed oil has been reported as a promising candidate for use as a plant-derived protectant of a variety of crops, from a range of pre-harvest and post-harvest insect pests. However, such extracts have not been widely used, despite the “boom” in the development of the crop in the tropics during recent years, and societal concerns about overuse of systemic chemical pesticides. There are many potential explanations to such a lack of use of Jatropha insecticidal extracts. On the one hand, the application of extracts potentially harmful to human health on stored food grain, might not be relevant. The problem of decomposition of phorbol esters and other compounds toxic to crop pests in the field needing further evaluation before such extracts can be widely used, may also be a partial explanation. High variability of phorbol ester content and hence of insecticidal activity among physic nut cultivars/ecotypes may be another. Phytotoxicity to crops may be further limitation. Apparent obstacles to a wider application of such extracts are the costs and problems involved with registration and legal approval. On the other hand, more studies should be conducted on molluscicidal activity on slugs and land snails which are major pests of crops, particularly in conservation agriculture systems. Further evaluation of toxicity to natural enemies of insect pests and studies on other beneficial insects such as pollinators are also needed.

“…Consequently, the use of these products has caused environmental contamination and human poisoning and has caused resurgence of some pest species and extinction of natural predators (Lima Júnior et al, 2010), along with selection of resistant insect species (Rodriguez & Omoto, 2001). An alternative control strategy involves using plant insecticides, with priority to materials obtained from endogenous plant species Geris et al, 2008;Sarria et al, 2011;Santos et al, 2011;Prophiro et al, 2012;Silva et al, 2012).…”

RESUMENEsta investigación tiene el objetivo de hacer una selección de especies vegetales que son propias de la región Amazónica con potencial de uso en el manejo integrado de la oruga militar tardía Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Para tal, fue evaluado la eficiencia de extractos hidroalcohólicos de 15 especies vegetales que se son de la región. Los extractos fueron producidos a partir de las hojas, o de la cáscara, o de liana de las plantas. La eficiencia de los extractos (30 mg.mL -1 ) fue evaluada sobre huevos y larvas de 3º instar de S. frugiperda. Se constató una variación de respuesta de la oruga militar tardía entre los extractos hidroalcohólicos. El extracto de la cáscara de Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. presentó mayor eficiencia en los huevos, y el extracto de las hojas de Bauhinia forficata Link presentó mayor eficiencia en las larvas. Estos resultados son fundamentales para el manejo de la oruga militar tardía, toda vez que, los efectos nocivos reducen las pérdidas en la producción de maíz en las primeras fases del desarrollo del S. frugiperda. Se concluye que los extractos de C. spruceanum y B. forficata fueron los más eficientes para los huevos y larvas de la oruga militar tardía.Palabras clave: Spodoptera frugiperda, insecticidas botánicos, manejo integrado de plagas. ABSTRACTThis study aimed to screen plant species from the Amazon region for the potential to be used in the integrated management of the fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). For this purpose, the efficiency of the hydroalcoholic extracts of 15 plant species from the Amazon region was evaluated. The extracts were obtained from plant leaves, bark, or vines. The efficiency of the extracts (30 mg·mL −1 ) was evaluated on eggs and third instar larvae of S. frugiperda. A range of reactions of the fall armyworm to the hydroalcoholic extracts was observed. The extract obtained from the bark of Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. presented the highest efficiency against the eggs, whereas the extract obtained from the leaves of Bauhinia forficata Link was most efficient against the larvae. These findings are essential for the management of fall armyworms because the deleterious effects in the initial stages of S. frugiperda development significantly reduce maize production. In conclusion, the extracts of C. spruceanum and B. forficata were more efficient for eggs and larvae of the fall armyworm, respectively.

“…It also have the anticancerous properties because of the presence of alkaloid "Jatrophine" in latex (Thomas, et al, 2008). From its seeds, products are extracted that are useful for the production of insecticides (Silva et al, 2012), soap, candles and pesticides. Jatropha seed oil has high values of density, flash point, lubricity and calorific value comparable to diesel (Momin, 2013).…”

The present investigation was conducted for mass multiplication of Jatropha curcas L. through axillary bud culture. For this nodal segment from 3-5 months old nursery grown plants were used as explants for axillary bud culture. The sterilization treatment involving dipping explants in 0.1 per cent HgCl 2 solution for 5 minutes resulted in minimum contamination and maximum establishment of nodal explants. The treatment MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA was the best for culture establishment, shoot proliferation and multiplication of the axillary buds which exhibited highest value in each parameter like establishment (76.1%), number of days taken for shoot initiation (3.1 days), length of longest shoot (6.8 cm), number of leaves on main shoot (7.1) and number of shoots per explant (6.3). Among different treatments for root initiation, half MS media fortified with 1 mg/L IBA, 3 mg/ L NAA and 0.25 g AC gave best result in maximum number of rooting percentage (60) with minimum time taken for root initiation (13.3 days), produced maximum number of roots per shoots (5.1) and length of longest root (4.9 cm) when established shoots were treated with it. Such produced plantlets showed nearly cent per cent survival after hardening and acclimatization. It showed that explants surface sterilized with 0.1 per cent HgCl 2 solution for 5 minutes inoculated in MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA and half MS media fortified with 1 mg/L IBA, 3 mg/L NAA and 0.25 g AC were best in shoot establishment and root development respectively for mass multiplication of J. curcas L. through axillary bud culture.
