Achivements

  • Crop loss or avoidable yield loss of litchi
    fruit due to infestation of erinose litchi mite, Aceria litchii  was estimated to be 31.11 %. This is the mean
    of crop loss observed during last three consecutive years study.

  • Fifty (50) chilli germplasms including 10
    local collections were screened against the attack of Polyphagotarsonemus latus during last several years. Out of the
    entries only few local collections were found to be resistant against P. latus. After several years screening
    trial it was found that the local collections viz. Krishna, Bhekuri, Mem
    jolokia, Kharika, Moni and  Konjolokia
    were found resistant against P. latus.
    The HOD, PBG has been informed about these germplasms for the breeding of
    resistant chilli varieties.

  • Forty (40)
    germplasms/varieties including 10 local collection of brinjal were screened for
    resistance against the attack of     Tetranychus
    mites and brinjal shoot and fruit borer. Results revealed that only one variety
    i.e. Pusa Purple Cluster and three local collections viz. Short Pink, Kharua
    Round, Kharua elongated were found to be resistant to spider mite. On the other
    hand 9 germplasms/varieties were found to be tolerant to BSFB. Only three
    locally collected germplasms viz. Short Pink, Kharua Round, Kharua elongated
    exhibited resistant against both the mite and the insect.

  •  Certain eco-friendly
    management practices (plant oils) were evaluated against litchi mite, Aceria
    litchii     .     Among the different plant oils, neem oil (Azadirachtin 10,000
    ppm) @ 3ml/l was found to be superior both in terms of mite control (78.92%)
    and B:C ratio of 3.08 compared to     Jatropha oil , Karanj oil ,Eucalyptus oil and Castor oil.

  • Among the eco-friendly control measures against
    spider mites in brinjal, polygonum leaf extract and Azadirachtin showed on par
    results both in mite control (85.20% and 88.64%) and B:C ratio (2.33 and 2.00),
    respectively. Therefore, next to the chemical acaricide, fenazaquin either     Polygonum or Azadirachtin may be considered as eco-friendly
    control of     Tetranychus mites in brinjal crop.

  • Mass multiplication of the predatory mite, Neoseilus
    longispinosus     on the prey mite Tetranychus urticae using wild
    amaranth as host crop was found to be best for harvesting maximum number of
    predatory mite after 21 days when released at 1:50 predator: prey ratio.

  • Biological control of Tetranychid mites in
    cucumber was tried using the predatory mite Neoseilus
    longispinosus      under polyhouse
    condition. Results showed more than 90% mite control was achieved when predator
    was released at 1:30 to 1:50 predator: prey ratio.
