Abstract:
The laboratory experiment was conducted to studies on screening of different groundnut genotypes (Pods) against Caryedon serratus Olivier at Department of Agricultural Entomology, Oilseed Research Station, Latur during academic year 2020-21. The relative preference by Caryedon serratus to twenty groundnut genotypes was studied on basis of fecundity, number of adults emerged, per cent adult emergence, mean development period, growth index, index of susceptibility, index of suitability, longevity of male and female and sex ratio. The test genotypes were grouped into five categories viz., resistant, moderately resistant, susceptible, moderately susceptible and highly susceptible based on the index of susceptibility. The genotype HOVTSB-I-2020-08 recorded minimum fecundity (11.33 eggs), low adult emergence (5.33), high mean development period (49.60 days), low growth index (0.95), low index of susceptibility (3.38) and low index of suitability (0.034) which shows the moderately resistance to Caryedon serratus Olivier. While genotype LSVT-I-2020-04 recorded maximum fecundity (26.67 eggs), maximum adult emergence (16.00), short mean development period (45.98 days), high growth index (1.30), high index of susceptibility (6.01) and high index of suitability (0.039) which shows moderately susceptible to Caryedon serratus Olivier.
