“…Field surveys of the pest status of H. virescens supported the hypothesis of genetic divergence among populations in host use. Throughout its range in the southern United States, Central America, South America, and the West Indies, H. virescensis a major pest on cotton (Hambleton, 1944;Harding, 1976;Stadelbacher, 1981), but in the San Joaquin Valley ofCalifornia, where H. virescens and cotton are both present, H. virescens tends to occur on hosts other than cotton (T. Leigh, pers. comm.).…”

“…In the United States, populations of this multivoltine insect feed on a variety ofgeographically restricted wild hosts as taxonomically distant as Geranium dissectum and G. carolinianum (Geraniaceae), Rhexia alifanus (Melastomataceae), Abutilon theophrasti (Malvaceae), Castilleja indivisa (Solanaceae), and Lupinus texensis (Fabaceae) (see lists compiled by Barber [1937], Brazzel et al [1953], Harding [1976], Stadelbacher [1981], and Egers et al [1982]).…”

When cotton, geranium, petunia, tobacco, tomato, and velvetleaf were presented simultaneously to strains of the Heliothine moth, Heliothis virescens (F.), from Arizona (AZ), Mississippi (MS), and North Carolina (NC), oviposition choices were similar, while a strain from the Virgin Islands (VI) was significantly different from both the AZ and MS strains. In the MS-VI sixhost test, the VI strain laid a higher proportion of its eggs on tomato and a lower proportion of its eggs on petunia than did the MS strain. Since petunia and tomato are in the same plant family (Solanaceae), differences between the strains in host preference do not appear to involve traits common to all members of a plant family. In the AZ-VI six-host test, the AZ strain laid a higher percentage of its eggs on tobacco and lower percentages on geranium and velvetleaf (Malvaceae) than did the VI strain. The percentages of eggs laid on cotton (Malvaceae) by the two strains were not significantly different. When moths were placed in cages with only tobacco and geranium, the AZ strain again laid a higher percentage of its eggs on tobacco than did the VI strain. However, when host choice was restricted to tobacco and cotton or velvetleaf and cotton, no significant difference between strains was found. Reciprocal hybrids ofthe AZ and VI strains were intermediate to the parental stocks in their preference for tobacco over geranium, indicating that a genetic mechanism was responsible for oviposition preference. The relevance ofthese findings to seemingly rapid fluxes in host range among members of the Heliothinae is discussed.

“…The insect pests attack all parts of the plant, but each pest is tissue specific (Grossi-de-Sa et al 2011). Lepidopterans, primarily species of the family Noctuidae, are the major insect pests attacking above-ground plant parts, specifically, the leaves and pods (Harding 1976). Other secondary insect pests include the soybean aphid ( Aphis glycines Matsumura), which originates from North Asia and has now spread across many parts of the USA and Canada .…”

“…The significance of wild hosts in the seasonal population dynamics of highly polyphagous cotton pests is somewhat conjectural and appears to vary regionally (Stadelbacher et al 1986). Surveys in certain areas e.g., southern Texas (Harding 1976), have suggested only moderate densities of Heliothis and Helicoverpa on native hosts during the earlyspring period, while major concentrations of both pest species have been documented on plants such as crimson clover. Trifolium incarnatum L., and Carolina geranium, Geranium carolinianum L., in other areas, e.g., the south¬ eastern states Brazzel 1965, Snow et al 1966).…”
