More Information

  • Thrips have developed resistance due to numerous mutations on neuroreceptors.

    Ultraviolet -absorbing film in greenhouses can control the number of thrips.

    The photosensitive areas in their compound eyes are identified.

    Ultraviolet light can affect thrips’ vision.

  • Insecticide resistance is one of the most critical problems for the control of thrips in agriculture systems. Thus, sustainable technologies are urgently needed. Thrips (Thysanoptera), a group of small fringed-winged insects, are destructive pests and cause severe economic lost to various crops worldwide. Among thrips, Megalurothrips usitatus (Bagnall) and Thrips palmi (Karny) are the dominant pests of melons and vegetables in tropical regions of China. In this study, it was found that field populations of these two thrips have developed a high level of resistance to multiple insecticides, and many mutations were detected in major insecticide targets (voltage-gated sodium channel and nicotinic acetylcholine receptors) by next-generation sequencing technologies. These results revealed the difficulties in their controlling. To overcome these difficulties, ultraviolet-absorbing film in greenhouses (UVa-FG) was evaluated for its control efficiency of the thrips and crop protection. The results showed that using UVa-FG achieved 96.67% and 97.69% of the control rate for these two thrips with an increase rate in crop yield of 22.5% and 14.3% for cowpea and Hami melon, respectively. Furthermore, the microscopic observation identified the responsive ommatidium specific to UV light in thrips' compound eyes. At molecular level, five visual genes were cloned and the expression levels of three visual genes were found significantly upregulated under ultraviolet light environments, suggesting they could be the key genes in the regulation of visual changes in different light environments in thrips. Our research demonstrated that thrips visual system could be used as a new environmentally friendly approach to control thrips.

Abstract: Insecticide resistance is one of the most critical problems for the control of thrips in agriculture systems. Thus, sustainable technologies are urgently needed. Thrips (Thysanoptera), a group of small fringed-winged insects, are destructive pests and cause severe economic lost to various crops worldwide. Among thrips, Megalurothrips usitatus (Bagnall) and Thrips palmi (Karny) are the dominant pests of melons and vegetables in tropical regions of China. In this study, it was found that field populations of these two thrips have developed a high level of resistance to multiple insecticides, and many mutations were detected in major insecticide targets (voltage-gated sodium channel and nicotinic acetylcholine receptors) by next-generation sequencing technologies. These results revealed the difficulties in their controlling. To overcome these difficulties, ultraviolet-absorbing film in greenhouses (UVa-FG) was evaluated for its control efficiency of the thrips and crop protection. The results showed that using UVa-FG achieved 96.67% and 97.69% of the control rate for these two thrips with an increase rate in crop yield of 22.5% and 14.3% for cowpea and Hami melon, respectively. Furthermore, the microscopic observation identified the responsive ommatidium specific to UV light in thrips' compound eyes. At molecular level, five visual genes were cloned and the expression levels of three visual genes were found significantly upregulated under ultraviolet light environments, suggesting they could be the key genes in the regulation of visual changes in different light environments in thrips. Our research demonstrated that thrips visual system could be used as a new environmentally friendly approach to control thrips.
