We conducted studies to examine distributional patterns of adult Bemisia tabaci (Gennadius) strain B (also referred to as Bemisia argentifolii Bellows & Perring) in cotton, Gossypium hirsutum L. , and to develop and validate a sequential sampling pla

Constant temperatures between 32–35°C or higher and fluctuating temperatures with a mean of 32°C or higher generally resulted in reproductive failure of pink bollworms, Pectinophora gossypiella (Saunders), if the exposure occurred in the larval a

A closed fumigation system containing a circulating saturated atmosphere of candidate chemosterilants (31 compounds, 26 of them analogues of tepa) was tested with the Pectinophore gossypiella (Saunders). Tepa and its analogue, ethyl ester of bis(1-az

Pink bollworm moths chemosterilized by fumigation with bis (1-Aziridinyl) phosphinic acid, ethyl ester, and released into field cages failed to suppress native populations. In comparison, moths irradiated with 10 krad of gamma radiation caused highly

Adult males from 3 laboratory strains (Sooty, APHIS, and WCRL) of Pectinophora gossypiella (Saunders), and from 3 sources (live trapped, from infested bolls, and overwintered in diapause) of native males were irradiated with 0–42 krad in increments

Seven benzyl and cinnamyl derivatives of 2, 4-di-tert-butylphenol and 1,3-benzodioxoles were tested for sterilant activity against Pectinophora gossypiella (Saunders). Five of the compounds prevented development of neonate larvae placed on larval die
