“…3), nor was gossypol found in any of several Hibiscus species investigated, including H. sabdarWa and H. tiliaceus (Fig.4). Although the claim about the presence of gossypol in A. esculentus was recently reissued (48), our negative results are in agreement with those of Bell et al (49) and Stipanovic et al (50), who investigated many cuttivars of the plant. In addition, Abelmoschus and Hibiscus species have no pigment glands typical for gossypol-producing plants (18,19).…”

Plants belonging to Malvaceae (about 90 species belonging to 33 genera) were analysed for the presence of gossypol by reversed-phase HPLC using absorbance detection at 365 nm, and the chirality and optical purity of gossypol were determined whenever the analysis was positive. Only plants belonging to the cotton tribe (Gossypieae) contained gossypol (detection limit better than 0.001%). In particular, no gossypol could be detected in ABELMOSCHUS ESCULENTUS (ocra), HIBISCUS TILIACEUS, H. SABDARIFFA, and HEREA BRASI-LIENSIS, earlier claimed to contain this compound. Gossypol-containing plants usually produced dextrorotatory gossypol of varying optical purity; an enantiomeric excess of (-)-gossypol was detected in only one plant, GOSSYPIUTN BARBADENSE.

“…Depending on local climatic conditions, P. seriatus spends 3–5 generations in association with each of these three host plant species in our study areas. The three chosen host plant species carry different suits of defensive chemicals (Scora, 1967; Schmidt & Wells, 1990; Williams et al., 2001). The host plants are available to P. seriatus at different times of the year, with some overlapping periods.…”

Host‐associated differentiation (HAD) is the occurrence of genetically distinct, host‐associated lineages. Most of the cases of HAD in phytophagous insects have been documented in specialist insects inhabiting feral ecosystems or in generalist parthenogens in agroecosystems. Herein we report HAD in the cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (Hemiptera: Miridae), a native, generalist, non‐parthenogenetic insect feeding on native wild hosts [horsemint, Monarda punctata L. (Lamiaceae) and woolly croton, Croton capitatus Michx. (Euphorbiaceae)] and on cotton [Gossypium hirsutum L. (Malvaceae)] in the USA. Examination of genome‐wide genetic variation with AFLP markers and Bayesian analyses of P. seriatus associated with three different host plant species at five locations in Texas revealed a geographic pattern of HAD. The geographic pattern of HAD corresponded with differences in precipitation among the locations studied. In three locations, two distinct lineages of P. seriatus were found in association with horsemint and cotton/woolly croton, whereas in two other locations, populations associated with the different host plants studied were panmictic. We suggest that precipitation differences among locations translate into heterogeneity in vegetation distribution, composition, and phenology, which altogether may contribute to the observed geographic pattern of HAD.

“…Pammel (1911) reported that chickens eating capsules of S. rhombifolia died; however, later feeding tests by Steyn (1934) were negative. Other species of Sida, such as S. spinosa L. (prickly fantails), however, do not have pigment glands, and gossypol is present in the seed tissues only at the same low levels (60 ppm) found in glandless cottonseed (Schmidt and Wells 1990).
