Honeycrisp, Ambrosia, Pippin, Gravenstein, and McIntosh are varieties of what?
Honeycrisp 23% of the harvest is affected. As a result of the Honeycrisp apple's growing popularity, the government of Nova Scotia, Canada spent over C$1.5 million funding a 5-year Honeycrisp Orchard Renewal Program from 2005 to 2010 to subsidize apple producers to replace older trees (mainly McIntosh) with newer higher-return varieties of apples, the Honeycrisp, Gala, and Ambrosia. Apple growers in New Zealand's South Island have begun growing Honeycrisp to supply consumers during the US off-season. The first batch of New Zealand-grown Honeycrisp cultivars being introduced to the North American market have been branded using the "HoneyCrunch" registered trademark. According to
Ambrosia fungi Ambrosia fungi Ambrosia fungi are fungal symbionts of ambrosia beetles including the polyphagous and Kuroshio shot hole borers. There are a few dozen species described ambrosia fungi, currently placed in polyphyletic genera "Ambrosiella", "Rafaellea" and "Dryadomyces" (all from Ophiostomatales, Ascomycetes). Probably many more species remain to be discovered. Little is known about ecology of ambrosia fungi, as well as about their specificity to ambrosia beetle species. Ambrosia fungi are thought to be dependent on transport and inoculation provided by their beetle symbionts, as they have not been found in any other habitat. All ambrosia fungi are probably asexual and clonal.
