【摘要】 本文报道赤眼蜂大量繁殖机械化的研究,介绍研制出的洗卵干燥机、粘卵机、接蜂机、卵卡寄生率测定器的工作原理,机械设计及主要技术规格,工作效率及应用质量。试验结果表明:各种机械效能设计生产能力可日产蜂量10亿头以上,适应于当前国内繁殖的赤眼蜂主要寄主蓖麻蚕卵和柞蚕卵。比手工操作的工效提高十倍以上,大大减轻劳动强度。更多还原

【Abstract】 The present paper reports the results of the preliminary study onthe machanized production of trichogramma wasps for pests control.Several machines and devices,such as the host egg washer and dryer,machine for preparing egg sheets,parasitizing machine,and apparatusfor determining rate of egg parasitism have been designed.The con-struction,principle and use of these machines are described.With thehalp of these improved devices the daily production of trichogrammahave been in creased to 100 million wasps,which is suffifcient for onerelease of the wasps to cover one hundred thousandmu.更多还原
