Using pesticide is detrimental to human health and environment but even knowing this farmer of Bangladesh, which is really a subject to concern. Using pheromone instead of pesticide is one kind of environmentally friendly solution having no residual effects. Hence, this study is organized with different statistical data on the basis of conducting different survey and experiment on using pheromone. Using pheromone is highly cost effective than other conventional agricultural practice. Yield of vegetable crops higher in case of pheromone use than conventional practice and BCR (Benefit Cost Ratio) is also higher in case of pheromone using field than conventional agriculture. The aim of the study is to sort out the problems and make solutions regarding popularize of pheromone to the farmers.
Key words: Pheromone, pest control, IPM
Pest infestation is one of the constraints for achieving higher production in agricultural sector. Bangladesh losses about 30% of its crops due to pest and diseases every year (BBS, 2007). The major problem of vegetable production is insect pest infestation which causes a huge loss in vegetables production. Using of pesticides is so much helpful for minimizing the infestation. Pesticide use in Bangladesh negligible until the 1970s, but now it is increasing in dramatic way (Rahman, 2003). Pesticides should use by following the instruction of expert personnel. But farmers use pesticides indiscriminately and in unscientific way that’s why insect pest developing resistance and minor pests become major pests and causing food safety hazards (EPA, 2005). That’s why we need alternative way to control pests. Pheromone is one kind of biological insect control methods having no residual impacts on human health and environment. According to Islam (2012), “The use of synthetic pheromones for environmentally safe insect control was postulated soon after the discovery of silk moth pheromone.” Pheromones are used as monitoring tools (Ridgway et al., 1990; Baker and Heath, 2004). Due to the safe and secure insect pest control many agrochemical industries are now suggesting to the farmers to develop mating disruption and mass trapping of rice stem borer in order to use pesticide (Cork et al., 2005b). “Pheromones are applied in slow release formulations, thus resulting in low exposure; residues of lepidopteran pheromones in pheromone- treated food crops have not been detected (Tinworth, 1990)”. Using of bait trapping for fruit fly control with a synthetic pheromone recoved53 to 73% yield lossessin cucurbits (IPM CRSP, 2003). According to Rakshit et al. (2011), because of the effectiveness in controlling fruit fly and higher economic returns approximately 90% of the farmers of Jashore district adopted cuelure pheromone traps. There is very few research works have conducted on pheromone in insect pest management. Only a few scientists worked on pheromone traps (Alam et al., 2005; Uddin, 2008; Mazumder and Khalequzzaman, 2010) in Bangladesh but still now nobody identify the pheromone from native insect. According to Islam (2012), the survey report on pheromone practice in Bangladesh agriculture is also limited and it’s conducted by Md. Azharul Islam in 2012. The objectives of this study are as follows: (i) to discuss the present scenario and future prospect of using pheromone trap in Bangladesh and (ii) to identify the problems facing by the farmers and solve the problems.
