A new pest suction machine to control Bemisia tabaci (Hemiptera: Aleyrodidae) in tomato greenhouses.

The sweetpotato whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is challenging to control using chemical pesticides owing to its resistance to many insecticides. Thus, there has been an increasing demand for alternative control measures. Thus, this study evaluated the efficacy of a newly designed pest suction machine to manage whiteflies on tomato plants (Solanum lycopersicum L.

Interbiotype hybridization between biotypes A and B of Liriomyza chinensis (Diptera: Agromyzidae).

Liriomyza chinensis (Kato) is a formidable pest of Allium species, especially the Japanese bunching onion Allium fistulosum L. Recently, a novel biotype of L. chinensis (biotype B) has emerged, which causes more severe damage than the native biotype A.

Detection of Two Biotypes of Liriomyza chinensis (Diptera: Agromyzidae) in Japan.

The larva of stone leek leafminer, Liriomyza chinensis (Kato), is known to infest alternately just below the epidermis and inner surface of hollow cylindrical leaves of allium crops, resulting in the formation of discontinuous linear mines (mine form: discontinuous). However, after the fall of 2016, a novel mine form of the same species (mine form: continuous) was detected in Welsh onion fields of Kyoto Prefecture, Japan. We hypothesized that these mine forms were associated with flies having different genetic backgrounds; hence, we compared the mine forms and the partial mtCOI gene of flies collected from Welsh onion fields from 2018 to 2019.
