Description |
The biology and seasonal incidence of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis was studied during 2011-12 on brinjal variety Punjab Sada Bahar at the Entomological Research Farm and Acarology Laboratory, PAU, Ludhiana. The different parameters of biology viz. incubation period, larval period, pupal period, oviposition, fecundity, adult longevity and sex ratio were studied during different seasons i.e. June, August and October. Observations on the seasonal incidence of BSFB on shoots and fruits were also recorded. The results revealed that there was significant difference in duration of all the biological parameters during three different seasons and minimum duration of incubation period (3.19 days), larval period (11.31 days), pupal period (7.11 days) was observed during August when mean temperature and relative humidity was 29.65ºC and 79.25 per cent respectively. The total life span was observed to be shortest during August followed by June and October. Studies on seasonal incidence revealed peak infestation on shoots during 31st Standard week(SW) and fruits during 32nd SW. Shoot incidence was also reported from 44th to 52nd SW and 14th to 18th SW but the intensity of damage was low. Similarly, fruit damage was also observed from 44th to 52nd SW but intensity was low. Further, this pest was reported to feed on crops like Lycopersicon esculentum (Tomato) and Solanum tuberosum (Potato) and weeds viz. Solanum nigrum (‘Makoh’) and Physalis minima (‘Bhumbla’) all belonging to family Solanaceae.
