The feasibility of marking the adult stage of Helicoverpa zea (Boddie) and Heltothis virescens (F.) by treating Gerantum dissectum L. with aqueous solutions of strontium chloride (SrCl2) or rubidium chloride (RbCI) was studied. G. dissectum is a majo

First generation (G1) larvae of the overwintered (parent) population of bollworm, Heliothis zea (Boddie), and of the tobacco budworm, H. virescens (F.), were collected in wild geranium, Geranium dissectum L. and G. carolinianum L., and then reared on

Coptophylla caroliniani induces several changes in Geranium carolinianum such as leaf edgerolling and the formation of erinea. These mites can kill the plant if the infestion occurs early in the growing season and they reduce seed production. Zusamme

Ovipositors of the female corn earworm, Heliothis zea (Boddie), contained large amounts of extractable sex pheromone only during scotophase. Quantitative gas chromatographic analysis of ovipositor extracts for (Z)-11-hexadecenal, the species' major p

Geranium dissectum L., a previously unreported host of Heliothis spp., was found infested with Heliothis zea (Boddie) and H. virescens (F.) larvae in Washington Co., MS, in May 1965. Because of cultural practices, this adventive plant from Europe has

Surveys from 1965 to 1977 of the native wild and introduced naturalized flora of the delta of Mississippi for F1 generation larvae of the overwintered population of Heliothis zea (Boddie) and H. virescens (F.) showed that H. zea larvae occurred at le

This paper is concerned with the dynamics and host plant relationships of Heliothis populations as they develop seasonally in the Mississippi Delta region, and the implications they have on strategies for Heliothis management. It will also consider t
