Potential decreases in crop yield from reductions in bee-mediated pollination services threaten food production demands of a growing population. Many fruit and vegetable growers supplement their fields with bee colonies during crop bloom. The extent to which crop production requires supplementary pollination services beyond those provided by wild bees is not well documented. Pumpkin, Cucurbita ...

This paper applies the concept of damage coefficients introduced in Houba and Kremers (2008) to provide an estimate of the cost of climate change in particular the cost of changes in mean regional temperature and precipitation to the fruit vegetation sector. We concentrate on the production of apples in the German ‘Alte Land’ region. The estimated cost of climate change on apple-growing in the ...

In Argentina there are two tephritid fruit fly species of major economic and quarantine importance: the exotic Ceratitis capitata that originated from Southeast Africa and the native Anastrepha fraterculus. In recent years, the use of fruit fly parasitoids as biocontrol agents has received renewed attention. This increasing interest has recently led to the establishment of a program for the mas...

The context for the production of bananas for export is characterised by a wide range of transport-times between producer and importer countries, and by the use of a single cultivar of banana (Musa spp., AAA group, cv. Cavendish Grande Naine). We investigated the green-life of pink banana (Musa spp., AAA group, Red sub-group, cv. Figue Rose Naine) for the different physiological ages of banana ...

There is a growing body of evidence to support the hypothesised links between consumption of antioxidant rich foods and the occurrence of obstructive airway disease. The main research question was to examine the relationships between two types of dietary exposure and two indicators of respiratory morbidity in Scottish adults. The relationships between dietary consumption of fruit, vegetables an...

Organic farming is rapidly growing due to its perceived potential for producing higher nutritional quality. However, studies of organicallyand conventionally-grown crops have not always shown differences between the systems. The objective of this research was to compare the antioxidant activities of organically-grown tomato to those from a conventional production system during postharvest cold ...

The pawpaw [Asimina triloba (L.) Dunal, Annonaceae] tree produces the largest edible tree fruit native to the United States (Darrow 1975; Layne 1996). This fruit, known commonly as the “poor man’s banana,” may reach up to 1 kg in size. Pawpaws grow wild in the mesic hardwood forests of 26 states in the eastern United States, ranging from northern Florida to southern Ontario (Canada) and as far ...

INTRODUCTION Although Hispanics are a rapidly growing ethnic minority in the United States, the effect of acculturation on the proportion of Hispanics who meet national objectives for fruit and vegetable consumption has not been fully investigated. Our objective was to determine the extent to which ethnicity and acculturation (indicated by survey language preference) are associated with fruit a...
