摘　　要：采用培养皿滤纸法研究了荔枝蝽雌雄成虫臭腺分泌物对萝卜(Raphanus sativus)、芥菜(Brassica juncea)和水稻(Oryza sativa)种子萌发及幼苗生长的影响。结果表明,荔枝蝽臭腺分泌物对3种植物种子萌发和生长都有明显的抑制作用,且随着浓度的增大,抑制作用增强。雌成虫臭腺分泌物的抑制作用比雄成虫更显著,且雌雄成虫臭腺分泌物对根的抑制作用均比对茎的抑制作用强。雌雄成虫臭腺分泌物浓度为7μL/mL时,对萝卜种子萌发的抑制率分别为53%和43%;雌雄成虫臭腺分泌物浓度为4μL/mL时,对芥菜种子萌发的抑制率分别为55%和47%;而雌雄成虫臭腺分泌物浓度为5μL/mL时,对水稻种子萌发的抑制率分别为15%和12%,且高浓度时种子不萌发。结果表明,荔枝蝽臭腺分泌物对植物种子根系的生长具有较强的活性作用。Using the petri dishes filter paper method, this paper examined the effects of Tessaratoma papillosa gland secretions on seed germination and seedling growth of radish, mustard and rice. The results showed that the T. papillosa gland secretions significantly inhibited seed germination and seedling growth of the three tested species, and the inhibitory effects increased with concentration increasing. The effect of female bug＇s gland secretions was more pronounced than the male＇s, and the inhibition on the root was more obvious than the stem. At the concentration of 7 IxL/mL, the inhibitory effects of the male and female bug＇s gland secretions on germination ration of radish reached 43% and 53%, respectively. At the concentration of 4 ptL/mL, the inhibitory effects of the male and female bug＇s gland secretions on germination ration of mustard reached 47% and 55%, respectively. At the concentration of 5 txL/mL, the inhibitory effects of the male and female bug＇s gland secretions on germination ration of rice reached 12% and 15%, respectively. At higher concentrations the tested species stopped in growth. The results of this study indicated the strong activity of T. papillosa scent gland secretions against the root growth of plant seeds.
