Description Investigations were made in the college farm and
department of Entomology, Agricultural College, Bapatla
during 1988-'89 to evaluate 15 different bhendi varieties
against major insect pests and their seasonal occurrence on
two susceptible varieties.
Bhendi varieties PS-2, HB-57, Punjab Padmini, Janardhan
and Parbhani Kranti were found moderately susceptible and the
remaining varieties were highly susceptible to fruit borer
(£jrJjs~~1t~ella) attack.
Bhendi varieties which were less preferred (PS-2, HB-
57, Punjab Padmini and Janardhan) by E. vittella recorded
prolonged life 1>eriod as well as larval-pupal index and low
per cent larval survival, pupal weight, pu?al weight index,
per cent adult emergence, growth index, susceptibility index,
survival index, fecundity a.nd fecundity index.
Hairiness of fruits had no effect on either egg laying
or fruit damage by E. vittella.
Bhendi varieties HB-57, PB-57 and EMS-8 were found
tolerant since they harboured minimum number (among the test
varieties) of leafhopper nymphs and low' jassid injury index;
while the remaining 12 varieties were susceptible to
leafhopper (A. biguttul a blguttula).
Dense hairs on lower surface of leaf and high
chlorophyll content of leaf affected leafhopper adversely.
Parbhani Kranti recorded significantly less fruit
damage and leafhopper population than Pusa Sawani but equally
susceptible to aphids.
Bhendi crop sown on first September was severly
infested by fruit borer and aphids where as 1st December sown
crop suffered heavily by leafhopper nymphs.
Significant correlation was not found between fruit
borer incidence and weather parmeters (maximum, minimum
temperatures . and relative humidity) while leafhopper nymphs
favoured low maximum and minimum temperature and more of
relative humidity where as aphids preferred high maximum and
minimum temperatures and less relative humidity for their
development.
