Abstract
The current study was designed to evaluate the efficacy of four plant extracts,i.e., cassia (Acacia farnesianaWilld),arbor-vitae (Platychladus [Thuja] orientalisEndl, mahogany [Swietenia mahogany (Linn.) Jaq], and pancratier-lily (Pancratiummaritimum L.), as protectants against the cowpea weevil (Callosobruchusmaculatus). Results obtained showed that at a concentration of 5 g crude extract/kg seed, there was a significant reduction in the percentage of egg hatching. The cassia and arbor-vitae extracts from leaves or seeds appear to reduce egg hatching (0.5 and 30.0%) and (4.0 and 26.0%), respectively. Complete inhibition in adult emergence was found by the ethanolic extract of cassia seeds. The extracts obtained from cassia mahogany leaves also showed strong ovicidal activity. The egg hatching percentage significantly decreased during the 8-month storage of cowpea treated with ethanol extract of cassia and arbor-vitae seeds with values of (52-53%) and (51-58%), respectively. The results also demonstrated that surface treatment of cowpea seeds with most selected extracts did not affect the germinative potential of cowpea seeds compared with the control extract the ethanol extract of cassia and arbor-vitae leaves which had 80 and 75% germination, respectively compared to the control 95%. Water absorption did not also differ significantly between all treatment and control samples. In conclusion, current study investigated that tested plant extracts can be used as cowpea seeds protectants and can be used in IPM program
