Transplanting Time of Rice as a Factor in the Occurrence of Outbreaks of the Smaller Rice Leaf Miner Hydrellia Griseola Falleacute;n (Diptera: Ephydridae)

Abstract

: The damage caused by the smaller rice leaf miner was severe when rice was transplanted in early May or early June. When rice was transplanted between these periods, the miner caused very little damage. It is suggested that the relation between adult emergence and the time of rice transplanting was the main factor in the occurrence of the outbreaks of the insect. © 1982, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
