Cardiochiles
Cardiochiles is a genus of braconid wasps with nearly cosmopolitan distribution. Species are larval endoparasitoids, primarily attacking lepidopteran hosts. The genus includes economically significant species used in biological control, particularly against noctuid pests in agricultural systems.
Chloridea virescens
Tobacco Budworm Moth, Tobacco Budworm
Chloridea virescens, the tobacco budworm moth, is a noctuid moth native to the Americas and a major agricultural pest. The species was transferred from genus Heliothis to Chloridea in 2013 based on genetic and morphological evidence. Adults are brownish with green tinge and distinctive wing banding. Larvae feed on buds, blossoms, and fruit of diverse host plants, causing significant crop damage. The species has developed rapid resistance to multiple insecticide classes, making management challenging.

Winthemia rufopicta is a polyphagous tachinid fly parasitoid known primarily for attacking larvae of Heliothis spp. (Noctuidae), particularly Heliothis zea and H. virescens, in agricultural systems. Adults emerge in spring with males preceding females by approximately one week. Females deposit eggs on host surfaces, with parasitism levels varying dramatically based on host behavior, size, and microhabitat. The species overwinters as diapausing maggots in shallow soil cells. Population dynamics are strongly tied to host availability, with spring declines and fall peaks in parasitism rates.
