First record of Homeopronematus anconai (Baker) in Japan and predation on Aculops lycopersici (Massee). AKIRA KAWAI, MOHD. MAINUL HAQUE (National Institute of Vegetables and Tea Science, Kusawa 360, Ano, Mie 514-2392, Japan), HIROSHI TANAKA (Osaka Prefectural Agricultural and Forestry Research Center, Shakudo 442, Habikino, Osaka 583-0862, Japan) and MIMORU SHIBA (Matsuyama Shinonome Junior College, Kuwabara 3-2-1, Matsuyama, Ehime 790-8531, Japan) Homeopronematus anconai (Baker) was found on tomato plants cultivated in greenhouses in Mie and Osaka Prefectures on July and October of 2000, respectively. These are the first records of this species in Japan. In both greenhouses, the plants were heavily infested by Aculops lycopersici (Massee). After the rapid population increase of H. anconai the A. lycopersici population decreased sharply, and we speculated that H. anconai regulated the population of A. lycopersici. An adult H. anconai consumed an average of 69.3 A. lycopersici deutonymph during a 24h experimental period in the laboratory.
