臺灣綠蘆筍的七種薊馬中，只有蔥薊馬Thrips tabaci Lind一種，已在南美洲哥倫比亞（British）內陸之綠蘆筍嫩芽上發現（Banllam F. L.,1968)，而其餘的六種均為臺灣的綠蘆筍上首次發現。其中雌成蟲體呈黑褐色的一種黑腹薊馬Frankliniella intonsa Trybom，本省約40年前已有紀錄(高橋1935) Frankliniella formosa Moulton為其異名(Kurosawa1968)。
Thrips tabaci Lind. was one of the seven asparagus thrips found in Taiwan which had been reported in South America and Columbia. The other six species were first discovered in Taiwan. The female of Frankliniella intonsa Trybom, was black brown species and has been reported in Taiwan around 40 years (R. Takahashi 1935) . This species was the synonymy of Flankliniella formosa Moulton. which was spreaded around Europe and the coastal region of Asia.
Although Flankliniella intonsa Trybom has many different kinds of hosts, however, green asparagus was the only host for the life cycle of this. species. During dry season, the adult and nymph could be found in the petals delicated buds and stems, even in the sepals of delicated stems when harvested.
There are 22 generations in the laboratory observation around a year. But in the field condition, the outbreak and reproduction could be affected by precipitation and rainy period. Therefore, the population decreased or disappeared during rainy season. But in dry season, the adults and nymphs fed on delicated buds at a number of averaged 20.
Egg, larval and pseudo-prepupal stage was only 1-3 days. The long-lived generation was 16 days (♀) and 15 days (♂) the short-life was 7 days (♀♂) and averaged 9. 2 days (♀) as well as 9 days (♂) . The longest longevity of female adult was 49 days, and the shortest was 17.7 days. The female adult oviposited 11-76 eggs in the life. Temperature influenced the oviposition and the favorite temperature for oviposition was 28°C.
