Agricultural Regions

AbstractBees are important within terrestrial ecosystems, providing pollination, which facilitates plant reproduction. Agricultural regions are large landscapes containing varying proportions of cropland, natural, and semi-natural habitats. Most bees are not restricted to any of these and move freely throughout, exploiting food and nesting resources in favourable locations. Many factors affect bee diversity, and knowledge of these is crucial for promoting healthy bee communities. The main objectives of this study were to compare diversity and guild structure of bee communities across a range of land disturbance levels within the Annapolis Valley, Nova Scotia, Canada, in habitats ranging from managed apple orchards to old fields. The two habitat extremes differed significantly; intensely managed orchards had significantly lower species richness (∼50%) than observed/estimated in old fields, but orchards with intermediate levels of adjacent natural/semi-natural habitat showed affinities to either extreme depending on the metrics used for estimating species richness. Species assemblages in orchards had lower proportions of several guilds, particularly cavity-nesters, bumble bees, and cleptoparasites, than other habitats. These guilds accounted for over 30% of bees collected in old fields but only 3–10% in orchards, increasing with habitat complexity. The use of guilds for assessing the health of bee communities is discussed.

The apple sucker, Psylla mali Schmidb., was first noticed in large numbers in Nova Scotia in 1919 and within a few years populations were dense in apple orchards throughout the Annapolis Valley (Dustan, 1924a). Dustan (1924b) and Gilliatt (1924) reported that a disease caused by Entomophthora sphaerosperma (Fresenius) was prevalent among adult apple suckers during this infestation. A decline in numbers followed this early infestation due, it was thought, to the fungus. However, about the time that this early infestation declined sulphur was introduced as a fungicide. General use of sulphur continued until about 1950 and the insect was not a serious pest during this period. This association of low density of the apple sucker with the use of sulphur and the general increase in numbers of the apple sucker after the organic fungicides, ferbam, captan, glyodin, etc. became common in Nova Scotia, led to the belief that sulphur rather than E. sphaerosperma had been largely responsible for the decline of the early infestation in the 1920's.

AbstractSolitary cavity-nesting bees, especially trap-nesting Megachilidae, have great potential as commercial pollinators. A few species have been developed for crop pollination, but the diversity, abundance, and potential pollination contributions of native cavity-nesting bees within agricultural systems have seldom been assessed. Our objectives were to compare the diversity and fecundity of cavity-nesting bees in Nova Scotia in natural ecosystems with those in apple orchards under three levels of management, using trap nests, and to determine whether any native bees show promise for development as pollinators. Our results show that species richness and numbers of bees reared from trap nests in commercially managed orchards, abandoned orchards, and natural habitats were similar, and species’ compositional patterns were not unique to specific habitats. Trap nests can be used to increase and maintain cavity-nesting bee populations within Nova Scotia apple orchards. Osmia tersula Cockerell (Megachilidae), which accounted for almost 45% of all bees captured and was the most abundant species nesting in all habitats evaluated, should be assessed for potential as a commercial pollinator of spring-flowering crops. The influence of natural cavities on bee species richness in trap-nesting surveys is also discussed.

AbstractThe beetle fauna of conventional, organic, and abandoned apple orchards was monitored in the Annapolis Valley, Nova Scotia, between May and September 1991. Treatment in the three types of orchards differed with respect to weed control, disease control, fertilization, and general care. The most commonly captured beetles in all three types of orchards were carabids, in particular, Carabus nemoralis Müller, Carabus granulatus Linné, Harpalus rufipes (DeGeer), and Pterostichus coracinus (Newman). In general, abundance of predaceous beetles was highest in the conventional orchards and lowest in the abandoned orchards. Generic composition of predaceous beetles was similar among orchards, although the abandoned orchards were characterized by high proportions of the larger carabids, C. nemoralis and C. granulatus, whereas the organic and conventional orchards were dominated by the smaller carabids, H. rufipes and P. coracinus. Although there were no significant differences among orchard type in the total abundance of non-predaceous beetles, the abandoned orchards displayed the greatest diversity of non-predaceous beetles, with the lowest diversity found in the organic orchards.

(1) Background: The European apple sawfly, Hoplocampa testudinea Klug (Hymenoptera: Tenthredinidae), can be an economically important pest in eastern Canada and shows preference for apple cultivars in Nova Scotia, Canada. We hypothesized that this preference could be due to oviposition by female H. testudinea (preference-performance hypothesis) during the bloom period or differential larval survival during development due to fruitlet physicochemical properties. (2) Methods: Fifteen commercial and experimental apple (Malusdomestica Borkh.; Rosaceae) cultivars located at the Kentville Research and Development Centre (Kentville, Nova Scotia) were chosen and examined for H. testudinea oviposition, larval performance during fruitlet development, fruitlet physicochemical properties and damage assessment at harvest from 2016–2019, inclusive. (3) Results: H. testudinea showed significant cultivar preference during oviposition, during development and at harvest, but the ranking of these cultivars was not the same throughout the season. Total impact by H. testudinea was consistent for most cultivars over multiple years of the study. (4) Conclusion: Correlation of oviposition with damage provided weak evidence for the preference-performance hypothesis. We propose that this relationship is weak due to differential survival of larvae during development.
