Economic Control Measures Against the Major Pests of Jute

Abstract

Field trials were conducted against the major pests of jute from 1972-74. Endrin, endosulfan, phosalone, fenitrothion, carbaryl + molasses and fenitrothion + malathion were applied five times at 1 5 day intervals against Apion corchori, Anomis sabulifera and Polyphagofarsonemus latus. Three years data w a s pooled and analysed statistically. Endosulfan 0.075% a.i. proved superior t o all other treatments.

Evaluation of Different Mutants Against Insect and Mite Pests With Natural Enemies in Coastal Jute Ecosystem

“…), indigo caterpillar (Spodoptera exigua Hubner), stem girdler (Nupserha bicolor Dutt), stem weevil (Apion corchori Marshall), grey weevil (Myllocerus discolor Bohemus), yellow mite (Polyphagotarsonemus latus Banks) and red mite (Oligonychus coffeae Nietner) were recorded on olitorius jute var. JRO-54 from seedling to harvest stages of jute crop in India (Das and Sing 1977). Rahman and Khan (2012) observed Grey weevil (Myllocerus discolor) as a voracious feeder of tender leaves of jute seedlings during 2nd week of May and remained active throughout the crop season with peak infestation of 33.56% plant damage and 36% leaf damage in the first week of June in 2004.…”

“…Pre monsoon rains followed by drought condition are congenial for the outbreak of semilooper and may lead up to 50% loss of crop as reported by Dutta (1958). Yellow mite (Polyphagotarsonemus latus Banks) and red mite (Oligonychus coffeae Nietner) are considered as the other major pests (Das and Sing 1977) in India, are destructive pests and attack both the cultivated jute species (Martinez and Mendez 1994, Roe et al 1996, Karmakar 1997, Chakravarthy et al 1998. The damage of yellow mite is generally known as "Telenga" or Telchita".…”

Identification and characterisation of female released sex pheromone components of jute semilooper, Anomis sabulifera Guenee (Lepidoptera: Noctuidae)

“…ute semilooper, Anomis sabulifera Guenee (Lepidoptera:Noctuidae) is a potential and major pest of jute, with larvae being the most destructive stage of pest that causes heavy damage by defoliation (Dutta, 1958). The repeated infestation by this pest compromises crop growth and induces profuse branching (Tripathi and Bhattacharya, 1963), thereby resulting in ultimate reduction of fiber yield to the tune of 30.50 -37.50 % in many varieties of C. olitorius (Das and Singh, 1977;Singh and Das, 1979). The pest is also known to feed on both pods and unripe seeds in jute crop cultivated for seed production (Rahman and Khan, 2006;Rahman and Khan, 2012a).…”
