Panchagavya
(10.00 %) and dasagavya (20.00 %) at
higher concentration restricted the adult
emergence to 76.66 and 70.00 per cent,
respectively. Cow urine (up to 50 %
concentration) had the least effect on adult
emergence. Of the six indigenous products
tested, two products containing neem i.e
neem fruit + red chilli + custard apple leaf
extract and neem seed kernel + Aloe vera
+ Calotropis + Clerodendron leaf extract
produced morphogenic effects in the adult
stage. In case of the neem fruit + red chilli
+ custard apple leaf extract, out of 46.94
and 16.96 per cent of larvae that
developed into adults (at 2.5 and 5 %
concentration, respectively), 10.00 and
3.33 per cent were abnormal adults,
respectively. The adults were smaller in
size with twisted wings. Likewise,
increase of neem seed kernel + Aloe vera
+ Calotropis + Clerodendron leaf extract,
at 1.0 per cent concentration, few adults
(3.33 %) out of 12.17 per cent of the total
adults were abnormal. The remaining test
products viz., panchagavya, cow urine,
dasagavya and chilli + garlic extract did not exhibit morphogenic effects on adult
stage of the test insets.
