Economic and ecological perspectives of farmers on rice insect pest management
Understanding farmers’ perception is important in the development of sustainable and cost-effective integrated pest management strategies. Hence, farmers’ perception on rice insect pests and pesticide use was evaluated by selected 112 farmers composed of 77% males and 23% females, over the rice growing areas of North Cotabato, Central Mindanao, Philippines. 62% of farmers that were interviewed ...
متن کاملHardpan and Maize Root Distribution under Conservation and Conventional Tillage in Agro-ecological Zone Iia, Zambia
Hardpans (plough/hoe pans) are commonly believed to restrict plant root growth and crop yields under conventional small-scale agriculture in sub-Saharan Africa. This study questions the notion of widespread hardpans in Zambia and their remedy under conservation tillage. Soil penetration resistance was measured in 8x12 grids, covering 80 cm wide and 60 cm deep profiles in 32 soil pits. Large and...
متن کاملA modelling methodology to assess the effect of insect pest control on agro-ecosystems
The extensive use of chemical pesticides for pest management in agricultural systems can entail risks to the complex ecosystems consisting of economic, ecological and social subsystems. To analyze the negative and positive effects of external or internal disturbances on complex ecosystems, we proposed an ecological two-sidedness approach which has been applied to the design of pest-controlling ...
متن کاملInsect Growth Regulators for Insect Pest Control*
Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental st...
متن کاملSemiochemicals for insect pest management
Methods for crop protection based on semiochemicals show advantages over methods based on conventional insecticides. Applications of semiochemicals for insect pest management have, however, been limited. Some recent studies carried out in an interdisciplinary research program by five research groups in Sweden are presented. In spite of the chemodiversity in nature, it is striking that many simp...
