為害落花生之薊馬類與落花生產量關係研究

陳文雄

摘  要

一、目前為害落花生之薊馬類主要是豆花薊馬(Taeniothrips distalis Karny)、花薊馬(Thrips spp.)及姬黃薊馬(Scirtothrips dorsalis Hood)等3種。

二、薊馬之發生以乾旱季節為主,為害情形以春作較秋作嚴重,發生月份以3月中下旬至5月中旬及10月至11月間之蟲口數最多。

三、薊馬類之猖獗與否,受氣候因子,尤其溫度及降雨量之支配。

四、薊馬之防治與否,對落花生植株之發育影響至鉅,與產量有密切關係。

五、依據本研究調查結果,為害落花生之薊馬類深具防治之價值。


A Study on the Relationship between Thrips and the Yield of Peanut

W. S. Chen

Summary

1. Taeniothrips distalis karny, Thrips spp, and Scirtothrips dorsalis Hood are the three species of thrips that attack peanuts in Taiwan.

2. The thrips are always outbreaking and with high population density in the drought season.  There have more serious damages were caused by the thrips in spring crops than in fall crops.  From the mid of March to the mid of May and from October to November are the favorable season for outbreaking.

3. Whether the thrips outbreaking or not, it will depend on the climate conditions especially temperature and rain-fall.

4. To control the thrips or not will effect the development and the yield of peanuts.

5. According to the experiment, it was found that the thrips must be controlled and it’s was worth to be done.

6. Advising the growers or farmers to control the thrips at the right time and providing methods to improve the yield of peanut.
