Abstract | Tangerine is a cash crop in Thailand which is heavily vulnerable to insect pests. Heavy use of pesticides has severely affected environment and people‘s health. This study was conducted to assess the biological pest management potential using pest attractive plant species to reduce the use of highly toxic pesticides and to improve the quality of the product and environment health. The study had three steps: a farmer survey to gather farmers‘ knowledge and experience of pest repellant and pest attractive plants, from which a few of such plants to be selected and assessed for attractiveness of insect pests infesting on tangerine; field survey coupled with insect pest population dynamics for assessing the status of tangerine associated plants in the field for their ability of attracting insect pests living on tangerine; two sequential field experimentation to evaluate the performance of selected pest attractive plants for reducing pest incidence on tangerine; In parallel, field investigation and farmer survey were carried out. The farmers‘ responses showed sixteen plant species having capacity for pest attraction. In the mean time, sixteen weed species were selected in the selected organically grown tangerine farm. These plants were allowed to grow with tangerine and tested their pest attractiveness for four key insect pests for 12 weeks. From this study, three weeds [viz. goat weed (Ageratum conyzoides), Siam weed (Chromolaena odorata), and buffalo grass (Paspalum conjugatum)] were identified for further studies and tested together with cowpea (Vigna unguiculata), rice (Oryza sativa) and chilly pepper (Capsicum frutescens) based on farmers‘ information in an organically grown tangerine farm. |
