This study was conducted to investigate infestation of thrips in mother fern green asparagus(Asparagus officinalis L.) cultivation and the effects of near ultraviolet ray-absorbing(UVA) film. The most harmful thrips species for asparagus was onion thrips(Thrips tabaci Lindeman) in the southwestern warm regions of Japan. Most of these species were detected in the upper parts of mother ferns in the beginning of mother fern establishment, whereas they were recognized in the lower parts thereafter. These species were parasitic on fresher leaves. The infestation of these species increased remarkably in May and increased promptly when insecticide was not sprayed until the middle of August. Use of UVA film caused a remarkable decrease in thrips, making the film useful for controlling damage and reduction of pesticide application in mother fern green asparagus cultivation.
