Abstract

The aim of the present study was to assess the potential of synthetic predatory cue containing sulphurous odours as an area repellent to reduce rodent damage. Groups of mature Rattus rattus of both sexes were exposed to 0.5%, 1% and 2% concentrations of 2,4,5-trimethylthiazole (TMTZ), a synthetic predatory cue, applied through cotton swab under laboratory and simulated indoor store conditions. Laboratory experiment revealed lower food consumption by rats from the treated side of chamber compared to the untreated side at all three concentrations of TMTZ exposed once in a week with up to 61.70% and 67.90% repellency in male and female rats, respectively. Daily exposure of TMTZ resulted in up to 84.90% repellency in males and 76.70% in females. Under simulated store conditions, 1% TMTZ exposed once completely prevented damage to treated bags containing wheat grains for up to 12 days in male and 14 days in female rats indicating sex-specific differences in response towards TMTZ. The present study suggests the potential of TMTZ in reducing damage caused by R. rattus under indoor storage conditions.

摘要

本研究的目的是评估含有硫磺气味的合成捕食线索作为区域驱避剂以减少啮齿动物伤害的潜力。成群的成熟家鼠在实验室和模拟室内商店条件下，两性都暴露于 0.5%、1% 和 2% 浓度的 2,4,5-三甲基噻唑 (TMTZ)，这是一种合成捕食线索，通过棉签施用。实验室实验表明，在所有三种浓度的 TMTZ 每周暴露一次的情况下，与未处理侧相比，处理侧的大鼠的食物消耗量较低，雄性和雌性大鼠的驱避率分别高达 61.70% 和 67.90%。每天接触 TMTZ 导致男性高达 84.90% 和女性高达 76.70% 的驱避力。在模拟储存条件下，暴露于 1% 的 TMTZ 一次可完全防止对含有小麦谷物的处理袋的损坏，雄性大鼠长达 12 天，雌性大鼠长达 14 天，表明对 TMTZ 的反应存在性别特异性差异。R. rattus在室内储存条件下。
