Name of technology Management of aphids through early sowing of mustard
Category : Entomology
Developed by (Centre/Division) : Entomology Division
Year of development : 1996
Brief description : Aphid infestation can reduce considerable amount of mustard production. Sowing of mustard seed in late October or early November provides opportunity to escape the attack of mustard aphids & in this way increased yield of mustard can be obtained without any application of toxic pesticides.
Location of application : Throughout the country

Name of technology Integrated Management of Cucurbit fruit fly, Bactrocera cucurbitace
Category : Entomology
Developed by (Centre/Division) : Entomology Division
Year of development : 2004
Brief description : Cucurbit fruit fly Bactrocera cucurbitae is a devastating pest of different cucurbit vegetables. In Bangladesh this pest became a major problem for the farmers as they invade the crops in high populations and devastate the cucurbit crops. Due to its nature of damage it very much hard to control this pest with insecticide. However an effective and cheap management strategy against this pest has already been developed by BARI scientists. The IPM package is as follows:

Sanitation: Collection and destruction of infested fruits along with larvae.

Pheromone bait trap: The sex pheromone ‘cuelure’ which mimics the scent of female flies attracts the male flies and traps them in large numbers resulting in mating distruption. A simple plastic container known as ‘BARI trap’ or Magic trap’ is used for deployment of the pheromones. The rectangular plastic container should have around 3-liter capacity and 20-22 cm tall. A triangular hole measuring 10-12 cm height and 10-12 cm base is cut in any two opposite sides. The base of the hole should be 3 cm above the bottom. Water containing two-three drops of detergent would be maintained inside the trap throughout the season. The pheromone soaked cotton/lure is tied inside the trap with thin wire. Fruit fly adults enter the trap and fall into the water and die. It is important that the water inside the trap is replenished often to make sure the trap is not dry. There is no need to change the pheromone dispenser throughout the cropping season.

The pheromone bait trap should be set in the cucubit field at a distance of 10-12m2 starting from first flower initiation and be continued till last harvest.

Community approach: Community approach of the IPM package is also very much necessary.

Location of application : Throughout the country

Name of technology Integrated management of brinjal shoot and fruit borer, leucinodes orbonalis Guen
Category : Entomology
Developed by (Centre/Division) : Entomology Division
Year of development : 2004
Brief description : Brinjal fruit and shoots borer (BFSB) leucinodes orbonalis Guen. is the most destructive pest of Brinjal. The yield loss caused by this pest has been estimated more than 85% in Bangladesh. Despite its seriousness farmers rely exclusively on the application of chemical insecticides to combat BFSB which has resulted in a tremendous misuse of pesticides in an attempt to produce blemish-free marketable brinjal fruits. Unfortunately even after repeated insecticide spraying the farmers could not control the pest properly as the field population became resistance to the commonly used pesticides. However BARI scientists have already been developed the following effective and economic IPM package to combat the pest.

Sanitation : Prompt removal of pest-damaged shoots that harbor brinjal shoot and fruit borer (BSFB) larvae from the initial period of transplanting.
Use of sex pheromone: Sex pheromone for BSFB (a combination of two chemicals) has been identified synthesized and is now commercially available to trap the male moths before they mae. Three milligrams (mg) of pheromone in a plastic tube baited in the suitable trap known as ‘BARI trap’ or popularly known as “Zadur phad”. Male moths are attracted to the trap captured and killed. The pheromone lure is hung through the center of the lid inside the trap in such a way that the lure is 2-3 cm above the water level of trap. The trap should be set just above the plant canopy. Bating should be started from 4-5 weeks after transplanting and continued til last harvest. A distance of 10 m2 should be maintained between the traps. The pheromone plastic tubes should be changed at every 60 days.
Total reduction or less use of insecticides: To allow natural enemies like Trathala flavoorbitalis (which is very much deadly against BSFB larvae) Trichogramma sp. etc. to proliferate total reduction or less use of insecticides is important.
Release of bio-control agents: Two bio-control agents egg parasitoid Trichogramma sp. (@ 40000 – 50000 parasitized eggs/ha/week) and larval parasitoid Bracon habetor (@ 800-1200 adult/ha/week) should be released in the field
Community approach: Community approach of the IPM package is also very much necessary.
