Abstract

In recent years, the damage caused by thrips has become a key factor impacting the winter and spring production of fruits and vegetables in Hainan Province, China. This study aimed to elucidate the effects of different pupation environments on pupal development and eclosion of chilli thrips (Scirtothrips dorsalis Hood) by analyzing pupal development and eclosion of chilli thrips in an indoor environment with simulated natural soils and water content. Soil type, soil water content, and temperature substantially affected the eclosion of chilli thrips during the pupal stage. Both a low soil water content of 1% and a high soil water content of 15% were not conducive to the pupation and eclosion of chilli thrips. Moreover, the results indicated an interaction between soil type and soil water and temperature and soil water content, affecting the eclosion of chilli thrips. Chilli thrips not only pupated in soil but also completed pupation and eclosion in other soil-less environments, such as tender mango leaves, stalks, plastic mulch, and weed fabric. This study suggests that in addition to adopting pest control measures that target the canopy layer of crops, appropriate measures such as increasing soil water content can also be implemented in the ground layer to enhance the overall effectiveness of pest control.

化蛹环境对辣椒蓟马蛹发育及羽化的影响。

近年来，蓟马的危害已成为影响海南省冬春果蔬生产的重要因素。本研究通过模拟自然土壤和含水量的室内环境，分析了不同化蛹环境对辣椒蓟马（Scirtothrips dorsalis Hood）蛹发育和羽化的影响。土壤类型、土壤含水量和温度对辣椒蓟马蛹期羽化有显著影响。土壤含水量低于1%和高于15%均不利于辣椒蓟马的化蛹和羽化。此外，土壤类型与土壤水分、温度和土壤含水量之间存在交互作用，影响辣椒蓟马羽化。辣椒蓟马不仅能在土壤中化蛹，还能在芒果嫩叶、嫩茎、地膜、杂草织物等无土环境中完成化蛹和羽化。本研究提示，除采取针对作物冠层的防治措施外，还可在地面层采取适当的措施，如增加土壤含水量，以提高害虫防治的整体效果。
