Abstract/ Executive Summary:

The experiment was carried out from April to May, 2011 at the laboratory of Mennonite Central Committee Bangladesh in Bogra district to know the efficacy of different soil amendments to control cucurbit fruit fly(CFF) Bactrocera cucurbitae.Seven treatments viz. Control (untreated), Dursban 20EC(@ 10l ha^-1), Furadan 3G(@ 10kg ha^-1), Neem oil cake (@ 1500kg ha^-1), Mustard oil cake (@ 1500kg ha^-1), Tricho compost (@2500 kg ha^-1) and poultry refuse (@ 1500kg ha^-1) were used in the experiment and each treatment was replicated thrice. A similar effectiveness was found with the use of Dursban 20EC (@ 10l ha^-1), Furadan 3G(@ 10kg ha^-1) and poultry refuse (@ 1500kg ha^-1) for controlling of puparium. The experimental findings indicated that the use of poultry refuse (@ 1500kg ha^-1) in soil is a non-chemical way and could be a good practice in destroying the puparia of cucurbit fruit fly effectively for the bitter gourd farmers to manage the menace of fruit fly.

Program Area: Pest Management

Commodity: Land management, Insects, Bitter gourd

Objectives:

In this experiment, testing of efficacy of different soil amendments on pupal stage of cucurbit fruit fly was important to get an alternative solution.

Methodology:

To know the efficacy of different soil amendment to control cucurbit fruit fly (CFF), Bactroceracucurbitae, the experiment was carried out in the laboratory of Mennonite Central Committee Bangladesh at Sadar Upazila of Bogra district from April to May, 2011. Treatments There were seven treatments viz. T1 = Control (untreated),T2= Dursban 20EC(@ 10l ha^-1), T3= Furadan 3G(@ 10kg ha^-1), T4= Neem oil cake (@ 1500kg ha^-1) and T5= Mustard oil cake (@ 1500kg ha^-1), T6= Tricho compost (@2500 kg ha^-1) and T7= Poultry refuse (@ 1500kg ha^-1). Experimental design The experimental design was completely randomized (CRD) and each treatment was replicated thrice. Larval and pupal management Larvae of cucurbit fruit fly, B.cucurbitaewere collected from infested bitter gourd of untreated plots. All infested fruits were kept in the rearing cage (12"×18") on a plastic tray. The maggots were in close visit for three to four days till they attained jumping stage. At this stage they became mature and ready to pupate. The test containers were earthen pot of 26 cm height with open top and 60 cm diameter. The top opening was covered with very fine mosquito net after releasing the maggots to prevent them from escaping. Soil was collected from the experimental field from 0-15 cm depth. Before being placed in the container the soil sample was sieved through 0.5 cm × 0.5 cm sieve and dried in hot sunny day. Materials of different treatments were collected from the local market. Treating soil by different amendments All the treatment materials were incorporated with soil of earthen pot according to the treatments. Dursban 20EC was applied with water in the soil @ 10 l ha^-1, Furadan 3G, Neem oil cakes, mustard oil cake, tricho compost and poultry refuses were crushed to make them dust and applied in the soil of the container as per the dosage specified in the treatments. In control container, only tap water was applied.

Achievement/Findings:

The present studies conclude that, against pupal stage of cucurbit fruit fly, B. cucurbitae, among six different types of soil amendments, the maximum percent of puparium was damaged by the use of Dursban 20EC(@ 10l ha^-1), use of Furadan 3G(@ 10kg ha^-1) and use of Poultry refuse (@ 1500kg ha^-1) which were 70.00%, 73.33% and 66.67%, respectively. When amendments were mixed with soil, it delayed the emergence of adult cucurbit fruit flies. Considering the experimental findings,poultry refuse (@ 1500kg ha^-1) in soil may be useful for the bitter gourd growers to manage the menace of fruit fly in a non-chemical way, this could be a good practice in destroying the puparia of cucurbit fruit fly effectively.
