The effect of diet and parasite load on female phonotaxis in the Texas field cricket, Gryllus integer

Female crickets respond selectively to variations in species-specific male calling songs. This selectivity has been shown to be age-dependent; older females are less choosy. However, female quality should also affect female selectivity. The effect of female quality on mate choice was examined in Gryllus integer by comparing the phonotactic responses of females on different diets and with different parasite loads to various synthetic models of conspecific calling song. Test females were virgin, 11-14 days old, and had been maintained on one of five diets varying in protein and fat content. Phonotaxis was quantified using a non-compensating Kugel treadmill which generates vector scores incorporating the speed and direction of movement of each female. Test females were presented with four calling song models which differed in pulse rate, but were still within the natural range of the species for the experimental temperature. After testing, females were dissected and the number of gregarine parasites within the digestive tract counted. There were no significant effects of either diet or parasitism on female motivation to mate although the combined effects of these variables seem to have an effect with no apparent trend. Control females did not discriminate among song types, but there was a trend of female preferences for lower pulse rates which are closest to the mean pulse rate for the species. Heavily parasitized females did not discriminate among pulse rates altho~gh there was a similar trend of high vector scores for low pulse rates. Diet, however, affected selectivity with poorly-fed females showing significantly high vector scores for pulse rates near the species mean. Such findings raise interesting questions about energy allocation and costs and risks of phonotaxis and mate choice in acoustic Orthoptera. These results are discussed in terms of sexual selection and female mate choice.

Donald Ziraldo Fonds, 1968-2012, n.d.

Donald J. P. Ziraldo, C.M., BSc., LLD was born in St. Catharines, Ontario on October 13, 1948 to Fredrick and Irma (Schiratti) Ziraldo. He graduated Denis Morris High School in St. Catharines in 1967, and received his B.Sc. in Agriculture at the University of Guelph in 1971. In 1974, Ziraldo was running Ziraldo Nurseries when he met Austrian born schoolteacher, chemist and winemaker Karl J. Kaiser. They realized that there was a gap in the premium varietal wine market and decided to plant a premium traditional European variety of grape vine species, the Vitis vinifera. This was an innovation in the Niagara region because the current wine producers were not using premium European grapes at the time. Ziraldo and Kaiser founded and then formally incorporated Inniskillin Wines Inc. in Niagara-on-the-Lake, Ontario on July 31, 1975. Ziraldo successfully lobbied General George Kitching, CEO of the LCBO, for a winery license. In 1975, Kitching granted him a winery license, the first in Ontario since Prohibition ended. From the beginning, there was a division of labour where Kaiser focused on the winemaking and Ziraldo focused on the marketing and promotion of the wines. Ziraldo also became president of the company. Ziraldo and Kaiser worked on improving their winemaking techniques and promoting their products and company. Ziraldo has been called ‘one of the founding fathers of the Canadian wine industry’, and it is widely acknowledged that both men played a large role in the success and growth of the Canadian wine industry. Together they pioneered the estate winery movement in Canada. A major turning point Inniskillin came in 1984 when Karl Kaiser successfully harvested the first Icewine crop from frozen grapes on the vine and bottled Eiswein Vidal (Icewine). In 1990, Inniskillin received worldwide recognition for this Icewine when their 1989 Vidal Icewine won the most prestigious award in the wine world, the Grand Prix d’Honneur, given at Vinexpo in France. This victory has been called ‘the award heard round the world’ and it launched Inniskillin into the international wine arena. At the same time, this helped lift the profile of Canadian wines in general. Inniskillin not only became Canada’s leading producer of Icewine, but it also became known for producing ‘one of the world’s great wines’. After the 1990 award, Ziraldo began a major public relations campaign to promote Inniskillin and build Icewine into a worldwide brand. He travelled broadly every year to promote the brand and products and networked extensively with politicians, celebrities, chefs, sommeliers, etc. To ensure worldwide and long-term success, Ziraldo introduced Icewine to Asia and the United States which were new markets. He developed a new Icewine glass with George Riedel. Tony Aspler has called Ziraldo ‘Canada’s Wine Ambassador’. Ziraldo was President of Inniskillin Wines Inc. (Niagara) from 1975 to 2006. In 1992, Inniskillin merged with Cartier Wines, and in 1993 Cartier Inniskillin Vintners Inc. merged with T.G. Bright & Co. Limited, forming the new company Vincor International Inc. Inniskillin wines was now a subsidiary of Vincor. Ziraldo became a Director at Vincor International Inc. from 1993 to 2004. From 1989 to the mid 1990s, Ziraldo also became President of Inniskillin Napa, in Napa Valley, California. Inniskillin purchased Napa Valley vineyards and produced wines under the Terra label. In 1994, Ziraldo set up a subsidiary estate winery of Inniskillin in Oliver, British Columbia which was called Inniskillin Okanagan Vineyards Inc. He became President of the winery. This started as a partnership between Inniskillin and the local Inkameep Indian Band in the Okanagan. In 2006, Ziraldo left Inniskillin and since that time he has been involved in other Icewine related ventures such as running Ziraldo Estate Winery and producing Ziraldo Riesling Icewine 2007. He also is in partnership with the Niagara based Equifera Estate Winery to produce Equifera Icewine. His most recent projects include planting Picolit grapes in his parent’s hometown, in a project called Picolit Di Fagagna and becoming Managing Director of the Senhora Do Convento Port Winery in Portugal. Donald Ziraldo was instrumental in the creation of the Vintners Quality Alliance (VQA) in Ontario and was its founding Chair from 1988-1995. The VQA was established as a regulatory and appellation system which secured the quality and origin of Canadian wines made under this system. The VQA designation and bottle label gave the consumer confidence that the wines they were purchasing were 100% local products. The VQA system was set up first in Ontario and then in British Columbia.
