Beet Armyworm

Spodoptera exigua, other wise called Beet Armyworm, has a relatively brief developmental time under field conditions (Ali & Gaylor 1991), permitting rapid cycling of generations. It also has a high reproductive capacity, with average calculated fecundities ranging from 604.7 to 1724.7 eggs per female (Wilson 1934, Hogg & Gutierrez 1980, Chu & Wu 1992). A simple calculation illustrates this point.

Assuming a population sex ratio of 1 female to 1 male, a realized field fecundity of 200 eggs (approx. 2 egg masses) per female...Read more

1. Monitoring of S. exigua populations needs to be implemented to mitigate future outbreaks.
2. Need to determine alternate hosts within 5-10 km of affected areas. Corn, tomato, cabbage and certain weed species eg wild calalloo as listed earlier should be examined.
3. Application of Sex Pheromones and Attractants...Read more
