A majority of the laboratories could not acquire ethics approval for the administration of substances not approved for medical use. Some laboratories faced obstacles to obtain ethics approval for substances approved for clinical use. Respondents communicated that ethics committees often lack background knowledge about the anti-doping context.Conclusions. Disapproval of research proposals may originate from concerns over the safety of the study, the fact that there is seldom a direct benefit to the participant, the consideration that volunteers may be incentivized to use prohibited substances, a lack of background knowledge about anti-doping, or the focus of research ethics committees on health research.Huanglongbing (HLB, citrus greening disease) in the major citrus-producing states of the United States is associated with Candidatus Liberibacter asiaticus (CLas), which is vectored by the Asian citrus psyllid (ACP). Surveys were conducted in Texas from 2007 to 2017 to assess the prevalence and titer of CLas in ACPs and citrus trees. ACP and citrus leaf tissue samples were collected from suspect trees in residential areas and commercial groves (orchards) and assayed for CLas by quantitative PCR. CLas detection in ACPs (2011) preceded that of citrus trees (2012) by several months. Annual incidences of CLas-positive ACPs and leaf tissue followed an exponential growth pattern over the survey period, varying from 0.03 to 28.7% in ACPs and 0.6 to 36.5% in citrus trees. There was a significant and positive relationship between the monthly incidences of CLas-positive ACP and leaf tissue samples. The proportion of HLB detection sites also increased with time, reaching 26 and 40% of commercial groves and residential sites, respectively, by 2017. Seasonal variations were observed in the incidences of CLas-positive AC
