Temperature seems to be a major factor which affects the overwintering strategy the aphid follows in different regions. Nevertheless, the role of the primary host in the distribution of genotypes that invest in different overwintering strategies has not been studied adequately. Although oviposition height could be a crucial factor for the fitness of overwintering eggs, it has rarely been investigated. Alternatively, this behaviour may have been selected as a mechanism to increase overwintering survival. In their second year of development, most third instars overwintered in the subsoil (> 250 mm). In the same area, the offspring generation of overwintering females was collected as eggs and firstinstar larvae within 12 breeding sites. However, each of these species can also be grown as a shortseason cover crop or, if climate allows, as an overwintering cover crop. At least in 1998, the exit of butterflies from overwintering sites was relatively sudden and coincided with the first spring rainfall event. Most of the 105 clones, which were collected in both years, overwintered on winter hosts. In many cases, cold hardiness ensures successful diapause during overwintering, thereby enabling the insect to survive the cold winter months. The prolonged arrested development during diapause may reduce the flight capacity of the overwintering generation. Males are supposed to die before the overwintering period, and are not present in overwintering sites. The removal of semi-natural habitats due to the intensification of agricultural practice can lead to a reduction in overwintering sites. They observed distinctly higher abundances of overwintering adult staphylinids compared to carabids, similar to the present investigation. The results also suggest the parasitoid has no mechanism of overwintering outside its hosts. Following the oviposition period, cages containing several thousand overwintering eggs of each population were placed in a field insectary. Aphids overwintering on winter hosts were found in all collection sites. Other genotypes are able to invest in both reproductive and overwintering strategies. Three tracer lamb experiments were conducted over two consecutive grazing seasons to highlight climatic influences on the level of overwintering survival. The exodus from overwintering sites in 1998 corresponded well with a sudden pulse of spring rainfall. Sheep were generally overwintered on grazing pasture and supplemented daily with a mean ration of 1.8 kg of concentrates per head. Initially almost all visits were made in summer but, more recently, increasing numbers of people have overwintered. Separating third instars into allochronic populations enabled differences in the overwintering behaviour of young and old third instars to be determined. By repeated sampling of overwintering females through winter, we analysed the impact of each of three resistance genes on adult survival. In addition, overwintering generation egg to adult mortality apparently reduced the progeny to only 23% of those observed during either summer generations. The number of people overwintering on bases can be as few as 10% of the peak number present during the summer resupply period. Abundance and species richness of overwintering staphylinids significantly increased with successional age of the wildflower areas and were always higher in older wildflower areas than in winter wheat. However, there is no published information available about species richness and abundance of staphylinid and carabid beetles overwintering in wildflower areas during the first years of succession. Although the intermediate clones have a selective advantage as they invest in two overwintering strategies, they have been observed at low frequencies in heteroecious aphid species. They did, however, account for most of the samples taken from tobacco in seedbeds and almost all of the samples collected from overwintering populations on weeds (table 2). Four of the six commonest genotypes were red, and one of these accounted for 29.6% of the samples from tobacco and 29.4% of those from overwintering populations on weeds. She believed that there were numerous spiders that exploited short grasslands and other sparsely vegetated habitats, and that during the cold months these became unsuitable for overwintering. Indications are that diapause in this species is regularly timed, since animals entered and exited overwintering sites at roughly the same time in both years of this study. The size column indicates the length of the census route established at each of the reproductive sites, and the size of the censused area of each overwintering site. One theory is that during the spring and autumn, spiders balloon only short distances probably searching for overwintering sites or food, much like spider mites and moths. Their summer puparia have pale cuticle, whereas the overwintering ones are more sclerotic: also, overwintering puparia often secrete a thick coating of wax, which is absent in summer forms. A field close to my home which was coppiced had previously sustained overwintering sheep. From the Hansard archive Example from the Hansard archive.
