PLANT PROECTION DIVISION

The division initiated its scientific activities as an Entomology Division with main objective to minimize crop losses due to ravages of insect pests, diseases, weeds, nematodes, and rodents. In 2009, it was renamed as Plant Protection Division in which plant pathology section was included. The main focus of this division is to promote eco-friendly management with combination of nuclear techniques to manage insect pests and diseases of major crops and fruits. Its major achievements are, 1) perfected male annihilation technique to manage fruit flies in guava and mango orchards. 2) developed biological control against sugar cane bores and cotton pests, 3) extended the biological control technique with the coordination of 10 private sugar mills in 8 districts of Sind. Now a days female attracting system for fruit flies and management of diseases of wheat, rice sugarcane and cotton are in progress.

Biological Control

Eco-friendly management of insect pests of cotton

Control of rice stem borers

Management of post-harvest losses in cereal grains and pulses

Disease management of major crops.


Management of Sugarcane Borers

Established 9 bio-control laboratories at private sector and all the laboratories are working satisfactorily

Treated 245,000 acres of sugarcane successfully with bio control technology during 2009-10

Enhanced the resistance in T. chilonis against insecticides with the help of low doses of irradiation

Increased initial survival of T. chilonis in sugarcane field with the provision of supplemental host

Reduced immunity in 3rd, 4th and 5th instars larvae of sugarcane borers with irradiation

Developed artificial larval diet for the rearing of Chrysoperla carnea

Eco-friendly management of fruit flies
Bactrocera spp

Applied successfully MAT in conjunction with bio-control agents for the control of fruit flies

Integration of MAT with biological control proved more effective than separate the treatment particularly on small scale.

Determined a three component based lure for the attraction of female fruit flies, however the female’s attraction was comparatively less than the males on methyl eugenol

Mass rearing of three fruit fly specie Bactrocera zonata, Bactrocera cucurbitae and Bactrocera dorsalis on artificial diets.

Collected two species of parasites parasitizing larvae and pupae of Bactrocera zonata in mango and guava.

Continue the mass rearing of B. zonata on artificial diet for the colony maintenance of the two parasitoids

Continue the mass rearing of two fruit fly parasitoids, Dirhinus giffardii and Trybliographa daci on natural host.

Providing MAT traps to the orchard growers on cash payment basis.

Eco-Friendly Management of Insect Pests of Cotton

Determined protein hydrolysate as the most suitable food material for the conservation of the natural enemies in the field

The irradiation dose of 100GY was the most suitable to induce F1 sterility in the Pink bollworm moths

F1 sterility was used as an effective tool of integrated pest management programme for cotton bollworms

Biological control in conjunction with behavioural control proved more effective for the management of cotton bollworms as compared to the separate treatments

Combination of Bt cotton with bio-control agents proved significantly effective for management of the insect pests.

Determined upper and middle plant canopy as the most suitable place for releases of the bio-control agents
