Aqueous extracts of Tephrosia vogelii and Hyptis suaveolens, and of oils of Azadirachta indica and Jatropha curcas, as well as the pesticide Furadan 5G were evaluated for their insecticidal activity against the maize cob borer Mussidia nigrivenella Ragonot in laboratory and field experiments. In ...

Over the past decade China has quietly emerged as the world’s third largest biofuel producer. Concerned over rising food prices, in June 2007 China’s central government banned the use of grain-based feedstocks for biofuel production and reoriented the country’s bioenergy plans toward perennial cr...

Biofuels in China: an analysis of the opportunities and challenges of Jatropha Curcas in Southwest China
This tropical crop is native to Mexico and Central America, but is cultivated in many other Latin American, Asian and African countries as a hedge. It has become of interest to various development agencies because it adapts well to semiarid marginal sites, its oil can be processed for use as a di...
Inventory of insects associated with Jatropha curcas L. (Euphorbiaceae) was conducted from June 2011 to May 2012 at 5 sites in southern and central Benin. Thirty-two major insect pests and 14 natural enemies, including 6 parasitoids and 8 predators, were recorded. The most important phytophagous ...

Many countries have understood that an alternative is needed to the problems of depletion of fossil fuels. Emphasis is therefore put on biofuel-producing crops. One of the most important biofuel-producing plants in tropical is Jatropha curcas L. Several biotic and abiotic constraints limit J. cur...

The effects of growing Jatropha in on-farm and on-station degraded lands were evaluated on carbon (C) sequestration and soil properties. Jatropha accumulated and added to soil significant amounts of C (305 kg ha−1 year−1) from the year one itself. Overall, a 3–5-year old plantation added per year...
