In Jondor region, cotton is damaged by more than 200 types of pests. One of the most common is turnip moth (Agrotis segetum), harmfulness of which reaches up to 18%. To preserve cotton from damage by turnip moth (Agrotis segetum), a complex system of measures is used, among which the leading place as the safest pest control measures is taken by agrotechnical combating methods that include changes of main environmental factors, inhibition of the development of pests and improvement of cotton growing conditions.

The Cal Poly philosophy of “Learn and Understand by Doing” has been integrated with problem-based learning and the use of the latest technology to produce a class that closely simulates real-life pest control situations. Goals of the class, Disease and Pest Control Systems for Ornamental Plants, are to teach students pest monitoring, control and problem solving techniques, the use of resources including the internet and journals, and the use of the latest pest control equipment and application techniques. Students are shown pest situations and then work in groups to diagnose the problem, investigate management strategies, apply control measures, and monitor results. Weekly class presentations inform the class of the various projects and help to teach the class organization and presentation skills. Student evaluations and test performance have demonstrated that students achieve class objectives substantially better with the problem-based learning approach than with the previous lecture-based approach to the class.

Aspergillus is a significant pathogen in zoological species, although information on environmental variables influencing fungal prevalence in zoological settings are lacking. The objective of the study was to estimate the prevalence of and to identify environmental factors associated with aerosolised Aspergillus spores at a zoological park to advance the understanding of fungal exposure as a first step towards improved mitigation strategies for susceptible animals. Twenty-one locations were sampled for presence of Aspergillus species using the SAS Super 180 Microbial Air Sampler, while twenty-two environmental factors were evaluated every two weeks at SeaWorld of California during two 12-month periods. In each period, the frequency of investigated environmental factors was compared between samples classified as positive or negative for Aspergillus species using logistic regression. Prevalence of Aspergillus was higher (P<0.05) during the second 12-month period (110/525 or 21 per cent), compared with the first period (62/483 or 13 per cent). In both periods, positive Aspergillus samples were associated with indoor sites without high-efficiency particulate air (HEPA) filtration systems and other infection control measures (adjusted OR=4.33 and 5.19, P<0.01) or outdoor sites (adjusted OR=2.50 and3.79, P≤0.05), compared to indoor sites with HEPA filtration systems and other infection control measures, after controlling for season. Burden of airborne Aspergillus can be higher in indoor sites without HEPA filtration systems than in outdoor sites. The use of HEPA filtration systems and other infection control measures can mitigate the burden of Aspergillus. Risk-based surveillance systems that target indoor areas without HEPA filtration systems can be an efficient approach for early detection of high burden of Aspergillus at zoological parks.
