| Abstract [eng] |
The object of the research is economically important pest tomato leafminer, Liriomyza bryoniae. The abundance of L. bryoniae most often is controlled by using chemical pesticides. One of the alternatives for traditional insecticides might be environmentally friendly, non-toxic photoinsecticides (photosensitizers). Knowing that tomato leafminers locate and recognize the suitable host-plants by plant-emitted volatiles, such plant-origin compounds (kairomones) could be used for insects’ attraction to the bait with photosensitizer. The aim of the study was to determine kairomones emitted by tomato leafminer L. bryoniae host-plants and investigate the effect of photosensitizers on tomato leafminer by choosing the most effective photosensitizing agent. Our results revealed that the photosensitizer hematoporphyrin dimethyl ether obtained by L. bryoniae adults induces lethal effects in the insects exposed to the sunlight during 5 min. Also, the first attractant for tomato leafminer was determined which can be attributed to kairomones. This kairomone can be an effective extra tool increasing the ‘sensitivity’ of the monitoring traps and also could be used for the attraction of the pest to the bait with photosensitizer. |
