Abstract/ Executive Summary:

A study was conducted to evaluate different integrated packages for managing the trunk borer, Batocera rufomaculata infesting jackfruit trees in farmer's jackfruit orchard at Kapasia Upazila under Gazipur district of Bangladesh, during 2009 - 2010 and 2010 - 2011. Among the six packages, P4 (inspection of orchard at 15 days interval + cut-open tunnel with the help of chisel and sharp haft knife + hooking the hole by sharp iron rod + aluminium phosphide placed into the hole and sealing the hole with bordeaux paste) was the most effective package and ensured the highest number of healed holes tree -1(3.16). The performance was the poorest in package P1 (inspection of orchard at 15 days interval + cut-opened tunnel with the help of chisel and sharp haft knife and hooking the hole by sharp iron rod) rendering 1.67 healed holes tree-1, which were statistically similar to P3 (injection of Ripcord 10 EC@ 1ml liter -1 water into the hole by using syringe + sealing the hole with bordeaux paste) and P5 (P1 + P3). Significantly the highest (p < 0.01) % degree of control (M) was 77.78% found in P4. The yield increase was highest in P4 (68.56%), while it was lowest in P3 (18.48%). The cost: benefit ratio was highest (1: 3.23) in P4, while it was lowest in P3 (1: 1.48).

Commodity: Jackfruit

Objectives:

Present studies were undertaken for developing an effective integrated management package based on effectiveness and benefit-cost ratio for management of the jackfruit trunk borer.

Methodology:

The study was conducted at farmer's jackfruit orchard in Kapasia Upazila under Gazipur district during 2009 - 2010 and 2010 - 2011. It was laid out at RCBD with six treatments and six replications. One jackfruit tree was considered as one replication of a treatment. About 20 to 30 year old trees infested by trunk borer were used. The study comprised the following six treatment packages including control. The treatments were: P1 (inspection of orchard at 15 days interval + cut-opened tunnel with the help of chisel and sharp haft knife and hooking the hole by sharp iron rod), P2 (placement of aluminium phosphide into the hole and sealing the hole with bordeaux paste), P3 (injection of ripcord 10 EC (cypermethrin) @ 1ml liter -1 water into the hole by using syringe and sealing the hole with bordeaux paste), P4 ( P1 + P2), P5 (P1 + P3), P6 ( untreated control). Data was recorded by investigations of the external features of the holes, the frass on the ground, the fresh bleeding sap around the holes and the number of fresh holes. The hole was counted at 2 m height of each trunk from soil level. The performance of each treatment was explained in terms of healing hole and recovery of the damage of infested trees, increase of yield over control and the BCR. The efficacy of different treatments was classified into four classes I, II, III and IV to represent the state of larval activity, with corresponding values (v) of 3,

2, 1 and 0 to calculate the degree of control (Sheng-Ying et al. 2009).

External features of the defecator holes No new holes and old holes had healed,	Class	Value	Larval activity
trees which recover damage gradually	I	3	Larvae had died
No new holes, no saw dust on the ground, no fresh bleeding sap and frass	II	2	Larvae were in a comatose state
No new holes, no saw dust on the ground but little bit bleeding sap, fresh frass	III	1	Larvae became weak and caused slight damage
New holes, fresh bleeding sap, fresh frass, saw dust on the ground	IV	0	Larvae were active and caused serious damage

Calculation was done by using the following formula:

Degree of control (M) = (v/3) X 100%

Mean value of the control - Mean value of the treatment

Reduction of infestation over control = -------------------------------------------------------------------------------------------------------------- x 100

Mean value of the control

Benefit Cost Ratio (BCR) = Net Return/Total management cost

The collected data were analyzed through MSTAT-C software in single factor RCBD, and DMRT was used to separate means.

Achievement/Findings:

Among the six packages, inspection of orchard at 15 days interval + cut-open tunnel with the help of chisel and sharp haft knife + hooking the hole by sharp iron rod + aluminium phosphide placed into the hole and sealing the hole with bordeaux paste was the most effective package against jack fruit trunk borer
