Oviposition and dispersal responses of the two spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) to fenvalerate and permethrin residues in soybeans Glycine max (L) Merrill

Donahue, Daniel Joseph January 1985 (has links)
Laboratory experiments were conducted to evaluate Tetranychus urticae Koch dispersal response to fenvalerate and permethrin. A petri dish spider mite trap which allows the partitioning of the dispersal response into spindown and walkoff categories was developed. Fenvalerate induced the more severe dispersal response. A greenhouse experiment was conducted to evaluate Tetranychus urticae oviposition site selection in response to residues of fenvalerate and permethrin, at two levels of residue deposition. When pyrethroid-free leaf surface was available, nearly all eggs were found on the untreated surface, away from the pyrethroid residues. When pyrethroid-free leaf surface was not available, a substantial number of eggs were found suspended by silk threads above the treated surface. The results were found to be in agreement with the general pyrethroid avoidance hypothesis. A series of greenhouse experiments were conducted to evaluate Tetranychus urticae oviposition response following impingement, and contact with residues of fenvalerate and permethrin. In all instances the pyrethroids were found to reduce the number of eggs oviposited. Mites recovered after several days, and oviposition returned to normal. The results did not lend support to the hormoligosis hypothesis of insecticide induced mite outbreaks. Field and greenhouse experiments were conducted to evaluate Tetranychus urticae oviposition response, over time, to soybeans which have received an application of fenvalerate of permethrin. The pyrethroids did not alter the soybeans in a way which improved the quality of the plant as a resource for increased levels of spider mite oviposition. / Master of Science / incomplete_metadata

Gas exchange characteristics of apple and peach leaves as influenced by European red mite and twospotted spider mite

Mobley, Kendrick Norman January 1989 (has links)
Three densities of European red mite (ERM) (<i>Panonychus ulmi</i> Koch) and twospotted spider mite (TSM) (<i>Tetranychus urticae</i> (Koch)) were maintained on greenhouse-grown 'Imperial Delicious' apple (<i>Malus domestica</i>) and 'Redhaven' peach (<i>Prunus persica</i>) leaves. As ERM- and TSM-days increased, apple leaf net photosynthesis (Pn), transpiration (Tr) , and chlorophyll content (TCHL) decreased linearly. TSM was more damaging to apple leaf gas exchange than ERM. Apple water use efficiency (WUE) declined similarly with increasing mite-days for both mite species. Apple specific leaf weight (SLW) decreased with ERM-days and increased with TSM-days. Peach Pn, Tr, and TCHL declined linearly for both ERM and TSM. Both mite species were equally damaging to peach leaf gas exchange. Peach WUE decreased with increasing ERM and TSM-days. There was no mite effect on peach SLW. The results from separate apple and peach studies indicate that peach may be more tolerant to mite feeding than apple. / Master of Science

Mezipodnikové srovnání mlékáren v ČR / Interfirm Comparison of Dairies in the Czech Republic

Louda, Tomáš January 2010 (has links)
The thesis deals with interfirm comparison of twelfe selected Czech dairies between 2005-2009. The firms are ranked by various multicriterial methods with financial analysis ratios used as criteria. Companies are divided into groups by using the classification method and selected dairies are also evaluated by the spider analysis. The differences between applied methods are evaluated, as well the strengths and weaknesses of individual dairies.

Ekonomická analýza společnosti Výtahy, s.r.o. / Economic analysis of the company Výtahy, s.r.o.

Konečný, Petr January 2011 (has links)
This thesis economically analyses the company Výtahy, s.r.o. First there are some pages about the company itself, what it produces, few words about its history and crucial moments and the situation on the market. In the theoretical part the chosen methods of economic analysis are depicted. Practical part focuses on the company Výtahy, s.r.o. The horizontal and vertical analysis of the assets, liabilities and profit and loss account is shown. There is a calcuation of net working capital and its demand. The effectiveness of the company is measured also by a system of logical inequations. Important part is devoted to ratio indexes -- rates of profit, return on sales or assets, solidity of the firm, equity ratio or turnaround period of assets or inventories. The economic value added is counted by two methods -- with the model from Department of industry and trade and with the net operating profit after tax model. I applied several of financial health models to predict and analyse, if the company is doing good or bad. I compared the competing companies among themselves through the last five years based on four criteria. And I used three methods for the final order of the companies. The last comparison is done thru Spider analysis and it shows the economical situation of three Czech elevator companies in last two years.
