Response of Brinjal ( Solanum melongena Guen.)
varieties for the resistant reaction against Brinjal
shoot and fruit borer (BSFB) and red spider mites
(RSM)

Abstract
An experiment was conducted to evaluate the response of twenty five brinjal varieties against brinjal
shoot and fruit borer (Leucinodes orbonalis) and red spider mite (Tetranychus cinnabarinus) during 2014
and 2015 at research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of
Jammu, Chatha. The pooled data for the both the years of the study revealed that the ten varieties were
showed tolerance, the five varieties were found moderately tolerant, the eight varieties were susceptible
and the two varieties found highly susceptible reaction against brinjal shoot and fruit borer. Similarly, the
response of brinjal varieties against red spider mite showed that the three varieties were moderately
tolerant, the four varieties had low resistance, five varieties were found susceptible and thirteen varieties
of brinjal were recorded as highly susceptible. The present research findings advocate that the varieties
showed promise against these dreaded pests helped the farmers to fetch more remuneration from the
crops and provide security for subsistence and livelihood.

Introduction
India has progressed as one of the leading vegetable producers in the world with a total annual
production of 162.18 million tonnes with 17.6 MT/ha productivity from an area of 8.99 million
hectares
[1]
. Jammu and Kashmir State accounts for 1395.5 MT total vegetable production
from 631 ha land with 22.1 MT/ha productivity
[1]
. Among the vegetable crops, Brinjal
(Solanum melongena Guen.) is an important and demand driven vegetable crop grown
throughout the world and cultivated in all the tropical, sub-tropical and temperate zones. It is
one of the most common and popular vegetables cultivated in approximate 7.11 lakh hectare
area with the annual production of 13.56 mt with productivity of 19.1 t/ha in India
[2]
. Insect
pest and disease infestation is one of the major constraints in increasing the yield potential in
brinjal
[3]
. However, in recent years the production of brinjal has been seriously affected due to
a steady increase in insect pest infestation, especially the fruit and shoot borer (BSFB),
Leucinodes orbaonalis Guenn. (Pyralidae: Lepidoptera) which reduce the productivity as well
as quality of the fruits. BSFB is practically monophagous but other plants belonging to family
Solanaceae are reported to be the hosts of this pest. Due to concealed mode of life, BSFB is
the most serious pest of brinjal
[4]
and hard to control with the repeated application of
insecticides. The yield losses caused by Leucinodes orbonalis have been estimated up to 70-92
percent
[5, 3, 6]
. Besides BSFB attack, brinjal crops are also susceptible to a large magnitude of
insect pests and non insect pest such as red spider mites (Tetranychus cinnabarinus) which
pose a heavy toll to brinjal cultivation by continuous sucking the sap, formation of web and
depletion of chlorophyll contents and thereby inflicting losses ranging from 30 to 40 percent
[7]
.
Materials and Methods
An experiment was conducted to evaluate the response of twenty five brinjal varieties against
brinjal shoot and fruit borer (Leucinodes orbonalis) and red spider mite (Tetranychus
cinnabarinus) during 2014 and 2015 at research farm of Sher-e-Kashmir University of
Agricultural Sciences and Technology of Jammu, Chatha. The experiment was laid out in a
randomized block design with three replication to evaluate the response of twenty five
