Commercial fresh-market tomato fields in southeast Arkansas were monitored forHeliothisspp. during 1981 and 1982. Caterpillar-caused fruit damage, most of which was due toHeliothis,was surveyed during regular plant examinations both years and during harvest in 1982. Oviposition byHeliothis zeain nearby corn plots was also measured during 1982. AlthoughH. virescenswas present in the tomato crop system,H. zeawas the predominant species. In 1981, highestHeliothisegg counts on tomato were found on 5 and 29 May. In 1982,Heliothisegg densities on tomato were very low until 30 June. Although fruit damage was greater in insecticide-free sections of fields during 1982, overall damage was considered to be quite low (ca. 1–2%) in all plots. The proximity of silking-stage corn appeared to be an important factor inH. zeaseasonal population patterns in the tomato system.
