AbstractIn western Canada, three wax-infesting moth species are serious pests of honey bee products, Vitula edmandsae serratilineella Ragonot, Achroia grisella (F.), and Plodia interpunctella (Hübner). The latter two species are found only in the Fraser Valley of British Columbia, while the driedfruit moth (sometimes called the bumble bee wax moth), V. edmandsae, is found throughout western Canada.Three female-produced pheromone components of V. edmandsae were identified as (Z,E)-9,12-tetradecadien-1-ol, (Z)-9-tetradecen-1-ol, and (Z)-11-hexadecen-1-ol, and field tested. Pheromone baits were used in traps outdoors and in bee equipment storage facilities in the Fraser and Okanagan valleys of British Columbia. The peak indoor trapping period occurred during May in the Okanagan Valley, while catches in indoor traps in the Fraser Valley were negligible throughout the entire trapping period. Catches in outdoor traps peaked during July in both regions. Traps baited with (Z,E)-9,12-tetradecadien-1-ol, alone or in binary combination with (Z)-11-hexadecen-1-ol, were significantly more attractive to male V. edmandsae than all other treatments tested. At one apiary, cumulative moth catch from a trap line 1.0 m from hives was significantly greater than that from a trap line 4.5 m away. The results suggest that a pheromone-based monitoring and control program for V. edmandsae is feasible.

Coast moles were studied and trapped from 1935 to 1945 at Agassiz, British Columbia. They cause economic damage in the lower Fraser Valley by injuring growing crops and by covering up to 15 per cent of the surface of a field with their hills.The moles ate almost any arthropod, annelid, or molluscan that they captured, but earthworms comprised 93 per cent of the stomach contents. Adults ate nearly twice their weight in earthworms daily, or 100–150 grams, representing more than 100 worms. The populations of moles apparently varied in proportion to those of the earthworms.The moles mated from January to early March. The young were born in March or April. Yearling females had two embryos; 2-year-old females had three; and mature females had four. Of 940 trapped during the winters, 45 per cent were over 1, and 6 per cent were over 3 years old. The average weight of mature 74 males was 74.3 ± 5.6 grams; the average weight of 30 mature females was 69.8 ± 4.1 grams.Natural control was ineffective. The disastrous Fraser River flood of 1948 lowered the numbers significantly, but recovery was rapid.Artificial controls tested included: poisons, caustic irritants, explosives, flooding, earthworm poisons, combinations of chemical fertilizers and irrigations, mechanical and chemical barriers, commercial mole destroyers, poison gases, deterrents, and traps. Only the last two were of value; crude flake naphthalene was a deterrent, and the scissors type was the most effective trap. In heavy infestations as many as three moles per man-hour were trapped. Naphthalene was expensive but protected small plots for up to 6 weeks. For economic control by trapping an area of 300 to 500 acres should be trapped in one season. Smaller areas are quickly reinfested, since the moles travel up to 1 mile.

AbstractZ8-tetradecenyl acetate (Z8-14OAc andZ8-tetradecenyl alcohol (Z8-14OH) were identified as sex pheromone components of the eyespotted bud moth, Spilonota ocellana (Denis and Schiffermüller) (Lepidoptera: Olethreutidae). Compounds were identified by gas chrornatographic-eleclroantennographic (GC-EAD) and GC-mass spectroscopic analyses and field tested in apple orchards in the Okanagan Valley, B.C. Although Z8-14OAc alone was attractive to male S. ocellana, the addition of 1–5% Z8-14OH strongly synergized its attraction. Field tests comparing the attractiveness of virgin female S. ocellana with various doses of a 99:1 blend of Z8-14OAc and Z8-14OH indicated the natural sex pheromone has only two significant components. A 99:1 blend of Z8-14OAC and Z8-14OH is suggested for monitoring and control of S. ocellana populations in British Columbia.

With the development of high-speed rotating machinery, the unbalance vibration feature of each rotor system has a greater influence on the work efficiency, bearing life, operational time, etc. Therefore, an active balancing system is necessary to automatically reduce the unbalance vibration in the process of rotor operation. This study introduced a novel liquid transfer active balancing system for the hollow rotors, and compensation mass was performed by balance liquid transmission between two pairs of contra-positioned chambers. The performance of this new balance actuator was analyzed, including balancing velocity, balancing accuracy, and the effect on rotor dynamics. A monitoring and control program was constructed to control the balance actuator. Two extraction methods of synchronic vibration were introduced and quantitatively compared through simulation. A control program was developed and the control accuracy was within 1 ms. Furthermore, the effectiveness of the new balancing system was verified through active balance experiments and the maximum speed was 15,600 rpm. The results indicate that the balancing system could effectively decrease the unbalance vibration of the rotor system within 10 s, and the amount of decrease was more than 80%.

An air monitoring program is in place at a wafer fab to characterize outdoor air quality and its potential impact on manufacturing processes. Airborne molecular contamination (AMC), and specifically acid contamination, was of particular concern as the facility incorporated 90-nanometer (nm) manufacturing technology. Impinger ionic analysis, passive and real-time reactivity monitoring, and litmus paper hue readings were among the techniques used to assess air quality. Historical data for each monitoring technique was evaluated and compared to determine the applicability of each monitoring technique for these purposes. Data from this monitoring program also offered an opportunity to evaluate the performance of chemical filters installed in makeup air handling units for their ability to remove AMC. This study presents the results of air monitoring, detailing outdoor air quality and how that air quality compares to established specifications; comparison of different monitoring techniques used in the study; performance of installed chemical filter systems; recommendations for improving acid contamination control and evaluation of selected options; and recommendations for overall AMC monitoring and control programs.

Wild animal meat harvesting and processing is signifi cantly different from classical livestock meat production and represents a challenge by itself.Implementation of concept “from forest to fork” encompasses influence of hunting ground ecology, type of hunting, fi eld evisceration of hunted game, meat inspection aft er shooting or transport etc. The objective of this paper was to propose a model for monitoring and control of food born pathogens in wild boar´s meat. Hazard analysis emphasized the importance of several pathogens: Mycobacterium spp., Salmonella spp., Trichinella spp., and a fi ve-step control program were proposed. The program includes management of microbial contamination of wild boar meat, control measures for live animals, control measures during hunting and aft er shooting, guidelines for offi cial meat inspection with specific details for control of identifi ed hazardous pathogens and control measures for wild boar carcasses processing. Th e research on presence of food born pathogens in wild boar meat is still scarce, while the Trichinella spp. live cycle is well described and there are relevant data about epidemiology and natural reservoirs of the parasite in this part of Europe, little is known about tuberculosis and salmonellosis prevalence in wild boar population. Thus, implementation of control program, with strictly defi ned control measures cannot be overemphasized, and should include veterinary offi cials as well as hunters and others involved in game meat chain.

The objective of this research is to gather sufficient elements to implement a vibration monitoring and control program in various companies in the Tecamachalco region, in accordance with the permissible exposure limits suggested by ISO 2631-1 and in compliance with the Official Mexican Norm NOM-024-STPS-2001. It is about ensuring the wellness of workers, reducing the occupational risk and potential accidents that may occur as consequence. An investigation was done to determine the operating conditions of the companies, then an analysis was done to determine the existing vibration levels and based on this, make the most appropriate proposal to reduce the risks of deterioration of the health of workers by cause of equipment vibrations. The contribution of the research consists of making employers aware of the risks that workers have when being in contact with mechanical vibrations for long periods of time, with their repercussions in the medium and long term.
