Effect of crude cottonseed oil containing gossypol on fertility of male and estrous cycle of femaleBandicota bengalensisGray and Hardwicke

Abstract

Crude cottonseed oil (CCSO) containing 0.01% gossypol was evaluated in the present studies to record its effect on fertility of male and estrous cycle of female lesser bandicoot rat, Bandicota bengalensis Gray and Hardwicke. Laboratory feeding of bait (cracked wheat and powdered sugar in 98:2) containing 5 and 10% CCSO to female B. bengalensis for 13 days in no-choice feeding test, had no significant effect on the duration of the estrous cycle. However, laboratory feeding of bait containing 10% CCSO to male B. bengalensis for 15 and 30 days duration in a no-choice feeding test, significantly (P50.05) reduced sperm motility (%) and viability (%) in cauda epididymal fluid of treated rats compared to untreated ones. The weight of seminal vesicles of rats treated for 30 days was found to be significantly less (P 50.05) than that for rats treated for 15 days. No significant effect of treatment was observed on the breeding success of rats, diameter of seminiferous tubules, cell count and association of various germ cells in testis. Further studies may be conducted by increasing the duration of treatment or by using CCSO containing a higher concentration of gossypol.

Histomorphological and biochemical changes induced by triptolide treatment in male lesser bandicoot rat, Bandicota bengalensis

“…The lesser bandicoot rat, Bandicota bengalensis Gray and Hardwicke has been reported as one of the major pest in crop fields throughout Southeast Asia [3][4][5][6]. The species is also known to spread many diseases to man and livestock [7][8][9][10][11][12].…”

Effect of triptolide on reproduction of female lesser bandicoot rat,Bandicota bengalensis

“…On the other hand, the repeated use of rodenticides leads to non-target toxicity hazards and the development of bait shy and resistance rodent populations (El-Deeb et al, 2011;Pelz et al, 1995), thus adversely affecting the rodent control programmes. Reproductive inhibition is an alternative strategy that has the potential to provide long lasting control (Agrawal et al, 2012;Singla & Garg, 2013;Tobin & Fall, 2006).…”

Toxicity of cholecalciferol to lesser bandicoot rat, Bandicota bengalensis: Biochemical and histopathological changes

“…Keeping economic importance of this pest in view, different management strategies including use of fumigants, traps, habitat manipulation, exclusion and proofing, bounties and compensation are opted but to a limited extent. New methods like fertility control are still in the developmental stages (Buckle and Muller, 2000;Witmer and Singleton, 2010;Singla, 2013, 2014;Singla and Garg, 2013;.…”
