How would high priority pests be reported in the Western Australian grains industry?

General surveillance activities have an important role in plant biosecurity for the early detection of pests (includes diseases) and for demonstrating area freedom. Currently general surveillance information for the grains industry in Western Australia is mainly collected though reports of suspect high priority pests to the state Department of Agriculture and Food (DAFWA). Little information is available on the likelihood that members of the grains industry would report a suspect high priority pest, where and who they report pests to, and the factors that influence their decisions to report pests. This study details a survey of members of the grains industry conducted to determine the reporting practices relating to plant pest and diseases in the grains industry. Results of the study indicate that growers preferentially report to agricultural consultants and the local DAFWA staff; whereas agricultural consultants and researchers are more likely to report to the DAFWA head office. Factors that influenced participants’ reporting of suspect high priority pests included the ability to eradicate the pest or disease, free examination of suspect samples and the desire for more information about high priority pests. The ranking of factors varied with the role the individual had in the grains industry.

Bactericidal kinetics of marine-derived napyradiomycins against contemporary methicillin-resistant Staphylococcus aureus

There is an urgent need for new antibiotics to treat hospital- and community-associated methicillin-resistant Staphylococcus aureus (MRSA) infections. Previous work has indicated that both terrestrial and marine-derived members of the napyradiomycin class possess potential anti-staphylococcal activities. These compounds are unique meroterpenoids with unusual levels of halogenation. In this paper we report the evaluation of two previously described napyradiomycin derivatives, A80915A (1) and A80915B (2) produced by the marine-derived actinomycete, Streptomyces sp. strain CNQ-525, for their specific activities against contemporary and clinically relevant MRSA. Reported are studies of the in vitro kinetics of these chemical scaffolds in time-kill MRSA assays. Both napyradiomycin derivatives demonstrate potent and rapid bactericidal activity against contemporary MRSA strains. These data may help guide future development and design of analogs of the napyradiomycins that could potentially serve as useful anti-MRSA therapeutics.     

Can general surveillance detect high priority pests in the Western Australian Grains Industry?

Initial detection of plant pests (includes diseases) is often made by the growers and consultants that work directly with crops; this form of detection is referred to as general surveillance. General surveillance activities have an important role in plant biosecurity for the early detection of pests and for demonstrating area freedom. In the Western Australian grains industry, reports of suspect high priority pests to the state Department of Agriculture and Food is the main form of general surveillance. There is little information on the level of knowledge of high priority pests in the grains industry in Western Australia and the ability of members to detect high priority pests if they were present. This study details a survey of members of the grains industry to determine their knowledge of the signs of high priority grains pests and the likelihood that they would detect a high priority pest if it were present in grain or crops. Knowledge of the signs of the high priority grain diseases, Karnal bunt and Barley stripe rust, were found to be higher than those of the high priority insect pests, Khapra beetle and Russian wheat aphid. A wide range of responses was collected from respondents’ self-rated likelihood of detecting each of these pests and diseases in crop or harvested grain. However, respondents were more confident in their ability to detect the two plant diseases than the two insect pests. The results of this study suggest that further training in recognition of the signs and symptoms of high priority grains pests is required to increase the ability of members of the grains industry to confidently detect and differentiate high priority pests from common pests in the course of routine activities.
