Abstract:

    Surveys of insects and other pests on longan were carried out from 1996 to 2001 in southern Taiwan. A total of 59 species of insect pests, eighteen species including 2 species of mites and 2 species of snails were found to be new record in Taiwan. Among them, the mango aphid (Greenidea mangiferae Takahashi), litchi fruit borer (Conopomorpha sinensis Bradley), longan psyllid (Neophacopteron euporine Yang), kerria insect (Kerria lacca Kerr), pink wax scale (Ceroplastes rubens Maskell) and termite (Odontotermes formosanus Shiraki) were considered as economic important. This report described the symptom of their injuries and percentage of infestation. Chemical trails showed that, 90% Methomyl WP、80% Fenthion EC、3% Carbosulfan G and 5% Fonofos G、and 40.8% Chlorpyrifos EC were very effective for controlling longan psyllid, litchi fruit borer, lac insect and termites , respectively.
