Population Dynamics of Nesidiocoris tenuis (Hemiptera: Miridae) on Sesame Planted in an Open Field in Chiba Prefecture, Japan

Abstract

Abstract We investigated the population dynamics of Nesidiocoris tenuis (Reuter) and recorded species of other insects observed on sesame in 2014 and 2015 in Chiba Prefecture, Japan. Nesidiocoris tenuis adults and nymphs occurred during or after the second half of August until the end of October or plant death. We observed one lepidopteran pest and four hemipteran species (except N. tenuis) including three pest species of some crops. These results indicated that sesame plants are potentially useful for collecting N. tenuis in a field in Chiba Prefecture. However, we should pay attention to occurrence of insect pests.
