A study was made of neonate larvae of Phthorimaea operculella.Host finding from soil-laid eggs and dispersal from hosts and nonhosts were first examined. Of first-instar larvae hatching from soil-laid eggs, 80% found the potato plant while roughly 50% found each of the other three plants (datura, tobacco, and tomato). Dispersal from potato, datura, and tobacco was very low, while on tomato it was higher and a high mortality was observed in the 24 h period. Dispersal from nonhost plants was high… CONTINUE READING
