Residual Effect of Different Temperature Regimes on the Developmental Stages of F1 Progeny of Callosobruchus Maculatus (F) (Coleoptera: Bruchidea) on Cowpea Seeds
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 6, Issue 6
Abstract
Residual effect of varying temperature regimes on the developmental stages of F1 progeny of Callosobruchus maculatus (F) was investigated on cowpea seeds at the Biology Laboratory of Federal College of Agriculture, Ibadan. A pair of teneral adults (male and female) of Callosobructus maculatus obtained from 100C, 200C, 300C and 400C was transferred into separate Kilner jars containing 25 seeds each, the control were from laboratory ambient conditions (29 ± 30C and 85 ± 5% relative humidity). The experiment was laid out in a completely randomized design and replicated four times. Total number of eggs laid, number of hatched eggs (eclosion) and total number of adults that emerged from each treatment were recorded and analyzed, using analysis of variance while treatment means were separated with the aid of Duncan Multiple Range Test at 5% level of significance. Adults C. maculatus obtained from the lower temperatures (10 and 200C) recorded higher fecundity (64.0 ± 3.4 and 61.0 ± 2.7) and adult emergence (52.8 ± 3.4 and 52.3 ± 3.2) respectively compared to those obtained from higher temperature regimes (30 and 400C) with 45.5 ± 1.5, 21.5 ± 1.4 and 41.8 ± 4.2, 18.7 ± 2.4 respectively. Similarly F1 adults of C. maculatus obtained from 100C recorded the longest developmental period of 38 days while the shortest developmental period of 16.2 days was recorded from the F1 adults reared under the temperature of 400C. Thus at longer developmental period, the females have the highest fecundity and adult emergence.
