Plasma 15gm.

Potential sterilizing effects of the atmospheric cold plasma on the carob moth, Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae) was studied under laboratory conditions by means of life history experimentation. The results showed that the population growth parameters of the carob moth decreased in all periods of 15 to 60 sec of plasma treatments applied on 1 –day–old eggs. Overall, 19.5% and 23.8% of reproduced eggs were fertile when the experimental males and females mated with normal moths in indirect treatments of 15 and 30 sec, respectively. The highest intrinsic rate of population increase, r, was in control (0.11 day-1) and the highest decrease in this parameter was in the 30 sec direct treatment (- 0.073 day-1). The results showed that cold plasma had an acceptable potential to sterilize the pest if plasma was applied at egg stage. This potential will be explored from the perspective of insect sterility technique and the genetical / physiological mechanisms involved should be studied in future.

本研究在实验室条件下通过生活史实验，探究了大气冷等离子体（atmospheric cold plasma）对角豆螟（Ectomyelois ceratoniae Zeller，鳞翅目[Lepidoptera]、螟蛾科[Pyralidae]）的潜在灭菌效果。结果显示，在对1日龄卵施加15秒至60秒等离子体处理的所有时段中，角豆螟的种群增长参数均出现下降。总体而言，在15秒与30秒间接处理组中，经卵处理后羽化的试验雄虫与正常雌虫、试验雌虫与正常雄虫交配后，其所产卵的可育率分别为19.5%与23.8%。种群内禀增长率（r）的最高值出现在对照组（0.11 d⁻¹），而该参数的最大降幅则见于30秒直接处理组（-0.073 d⁻¹）。结果表明，若在卵期施加冷等离子体处理，其对该害虫具备可观的灭菌潜力。未来可从昆虫不育技术的视角进一步挖掘该潜力，并深入探究其所涉及的遗传与生理机制。
