Pest Management in Traditional Tropical Agroecosystems: Lessons for Pest Prevention Research and Extension 总被引:1,自引:0,他引:1
Helda Morales 《Integrated Pest Management Reviews》2002,7(3):145-163
Based on current agroecological theory and IPM practices, this review explores the role of traditional practices, involving
site selection, soil management, timing of planting and harvesting, crop resistance, intercropping, weed management, harvest
residue management, post-harvest management, natural enemies management, mechanical control, repellents and traps in the natural
regulation of potential pests. In synthesis, the literature suggests that although pest management professionals focus their
efforts on pest control, the preventative approach taken by traditional farmers is more effective. Potential constraints to
the implementation of this preventive pest management approach include:(1) lack of integration of ecological theory and pest
management, (2) lack of cooperation among social and biological scientists, and (3) lack of real efforts to work with farmers
as equals and support mechanisms that protect their knowledge.

Imports of pesticides have long been subsidised for use in the cocoa agroforests of the humid forest zone of southern Cameroon.
With the liberalisation of the cocoa and pesticides sectors and the devaluation of the local currency (CFA franc), farmers
are facing fluctuations in the price paid for cocoa and the high cost of farm inputs. Without the support of the extension
services, they themselves have developed traditional integrated control methods based on the use of plant extracts mixed with
conventional pesticides. From a survey of 300 cocoa farmers, the study assesses the farmers' command of these methods, the
pests controlled, the problems encountered and the institutional constraints in the definition and dissemination of integrated
control methods. The study concludes with recommendations for research and development towards the better definition and dissemination
of integrated control methods.

We interviewed half of the mango-growers in northern Benin, including 15 farmers involved in a regional fruit fly project, and held focus group discussions with women fruit-pickers. They were asked about pest management and their knowledge of a weaver ant, Oecophylla longinoda. All considered low yields due to fruit flies to be the principal constraint upon mango production, estimating economic losses to be between 20 and 45%. None could recognize damage during the first 2 days after fruit fly egg deposition. On-farm research persuaded farmers to stop using insecticides and it also changed negative perceptions of Oecophylla. Over 80% of the farmers involved in on-farm research, compared to 25% of those not involved, reported Oecophylla to be beneficial. All fruit-pickers knew that ants protected mango from fruit flies, with 60% attributing better mango quality in terms of appearance, shelf-life and sweetness to the presence of Oecophylla. Nevertheless, 40% of the pickers still considered weaver ants a nuisance pest during harvest. Ways of reducing this nuisance need to be developed for Oecophylla to gain wider acceptance by mango-growers. 相似文献
