Haemonchus contortus is the most prevalent and pathogenic nematode of sheep in tropical areas. The objectives of this study were to assess the frequency of the F200Y polymorphism on the ?-tubulin gene in third-stage larvae of H. contortus from 33 sheep flocks in São Paulo state, Brazil, and to associate this frequency to risk factors based on farm management practices. The resistance allele frequency varied from 9 to 74%, and the resistance genotype frequency varied from 0 to 66.7%. Resistance genotype frequencies higher than 40% were associated with multiple risk factors - new sheep farming enterprises, the absence of farm records, the use of Dorper and Suffolk breeds, rotational grazing, the lack of wetlands on farms, pasture sharing with cattle or horses, frequent incorporation of animals into the flock, semi-intensive farming systems, whole-flock treatment, failure to use the FAMACHA method, lack of the dose-and-move practice, anthelmintic rotation after each application, visual estimation of animal weight for treatment, and lack of drug combination use. It can be concluded that genotyping the F200Y polymorphism can be used to monitor the resistance in sheep flocks and the knowledge of management strategies at the farm level is important to identify drug resistance related factors. |

Laboratory studies with the stink bug Chinavia erythrocnemis (Berg) (Hemiptera: Pentatomidae) were conducted to evaluate the effect of reproductive structures of cultivated plants, on nymph and adult performance, and adult preference. Results indicated that nymphs were able to complete the development on all plants evaluated. Nymph developmental time was significantly shorter on immature soybean pod [Glycine max (L.) Merrill], compared with immature green bean pod (Phaseolus vulgaris L.), immature siliques of canola (Brassica napus L. var. oleifera), and immature ear heads of wheat (Triticum aestivum L.). Nymph survivorship was superior on soybean (60%), decreasing on the remaining food sources (< 38%). Fresh body weight of females and males at adult emergence was higher on green bean and on soybean, compared with wheat and canola. Survivorship of adults after 40 days was highest on soybean (80%) and on green bean (65%), and lowest on canola (25%). Females of C. erythrocnemis reproduced on all food sources tested, except on canola, on which no female laid eggs. The fecundity and longevity of adults were significantly higher on green bean and on soybean compared with wheat and canola. In general, adults gained weight over time when fed on green bean (18%), followed by soybean (3.4%). On wheat and on canola, the bugs lost weight over time (− 14.9% and − 27.4%, respectively). In general, soybean pod was preferred compared with green bean, canola, and wheat; green bean was preferred over wheat and canola; and canola was preferred to wheat.
