abstract
The leafminers of genus Liriomyza (Agromyzidae: Diptera) is a polyphagous pest capable of infesting a wide variety of horticultural crops. Formerly, they were categorized as a pest of minor importance. But now, it invades many regions of the world due to inadequate quarantine procedures. Owing to its extended host range, presently it becomes an economic pest of native as well as invaded regions of the world. Moreover, the development of insecticide resistance also attributed to the rise in pest status. The most commonly observed reason for the outbreak of leafminers is inappropriate use or exploitation of insecticides and their impact on natural enemies. This indicates that there is an imperative need to made further improvement in pest management tactics. The management of Liriomyza is still continued to be the topic of extensive research and study. In order to develop a prompt management tactics, the basic information such as species composition, host range, distribution, seasonal abundance and biology of the pest has to be acquired. The cultural practices such as mulching and use of vermicompost were more appropriate regarding sustainable management. The use of yellow sticky traps attracted more number of leafminer individuals when compared to other traps. Regarding natural enemies, there were about 41 species of parasitoid under four families reported in Asia and about 140 species of parasitoid have been reported over the world. Among that about 23 species have been successfully used in biological control programme. In case of chemical control, both synthetic as well as natural insecticides (Botanicals) have been extensively researched and commonly used by the farmers but the effectiveness of these insecticides has been reduced due to their indiscriminate use. Thus IPM strategy is a comprehensive technique seeks to provide an economical and effective control measures. In this article, a gist of information of the pest leafminer and various management techniques for leafminer management recorded were discussed.
