“…For example, many Lepidoptera, Diptera and Hymenoptera rely on energy gained from nectar to undertake mating flights, for dispersal and/or migration, and to find suitable places to lay their eggs. Butterflies tend to exhibit lower fecundity when nectar is limited (Boggs & Ross, 1993), and the hoverfly Episyrphus balteatus has greater longevity when fed a sugar and protein-rich diet (Pinheiro et al, 2015). Bees require both pollen and nectar to feed to their offspring.…”

“…In wheat crops (Triticum aestivum L.), the agronomic importance is at the larval stage, where aphid predators (Schmidt et al, 2003;Bugg, Colfer, Chaney, Smith, & Cannon, 2008) can consume up to 2,000 aphids (Dib, Simon, Sauphanor, & Capowiez, 2010;Hogg, Bugg, & Daane, 2011). Meanwhile, adult hoverflies feed on nectar and pollen, whose energy (Van Rijn, Kooijman, & Wackers, 2013) increases the reproductive rate (Laubertie, Wratten, & Hemptinne, 2012) and longevity (Pinheiro, Torres, Raimundo, & Santos, 2015). Because of the importance of floral resources to hoverflies, many studies have been conducted to promote the action of this natural enemy in crop fields using landscape management (Hickman & Wratten, 1996;Bokina, 2012;Amaral et al, 2013;Gontijo, Beers, & Snyder, 2013;Martínez-Uña, Martín, Fernández-Quintanilla, & Dorado, 2013;Haenke et al, 2014).…”

<b>Distance from the edge of forest fragments influence the abundance of aphidophagous hoverflies (Diptera: Syrphidae) in wheat fields

This study aimed to evaluate the influence of the distance from the edge of native forests on the abundance of aphidophagous hoverflies in wheat fields. The study was conducted in four commercial fields in the North of Paraná State, Brazil, during the wheat crop season of 2009. Two transects were surveyed parallel to the edge of the forest at two distances: 25 ("near") and 525 meters ("far") from the edge. The abundance of hoverflies was compared using a χ 2 test (p ≤ 0.05). In total, 1,845 hoverflies adults were collected, which represented 15 species and three genera. The most abundant species was Allograpta exotica (60.43%), followed by Toxomerus dispar (17.78%) and Toxomerus watsoni (7.26%) (Diptera: Syrphidae). An important inference was that all fields showed a higher abundance of aphidophagous hoverflies closer to the edge of the forest (25 m) during the wheat tillering stage. The initial abundance of aphidophagous hoverflies in wheat fields is likely greater near the edge because of the availability of resources in the surrounding forest that enhance hoverfly survival during periods of low aphid infestation.

“…In this study, lipid content of adults that fed on sucrose solution was much higher than those that fed on a mixed diet sucrose solution and A. graveolens pollen. On the contrary, higher lipid content has been observed in hoverflies that fed on honey and pollen, compared to those that fed on honey alone (Pinheiro et al, 2015). The inconsistency of the results could be due to the different species tested or to A. bipunctata's physiological processes.…”

A Floral Diet Increases the Longevity of the Coccinellid Adalia bipunctata but Does Not Allow Molting or Reproduction

Adalia bipunctata L. (Coleoptera: Coccinellidae) is a generalist aphidophagous coccinellid and an important natural enemy in many agroecosystems including orchards. Coccinellid species have been observed to consume non-prey food like nectar and pollen, but the value of these foods for A. bipunctata is poorly known. The objective of this study was to determine the effect of different prey and non-prey diets on A. bipunctata larval development and adult longevity and fecundity. Larval development was studied on three prey diets: The aphids Dysaphis plantaginea and Myzus persicae and Lepidopteran eggs of Ephestia kuehniella; five flower diets: Matricaria chamomilla, Daucus carota, Fagopyrum esculentum, Anethum graveolens, and Sinapis alba; four pollen diets from three plant species: Typha angustifolia, Malus pumila (two varieties) and A. graveolens; and 1 M solutions of three sugars: glucose, fructose, and sucrose. Adult longevity and fecundity were tested on one prey diet (E. kuhniella eggs), three flower diets (F. esculentum, A. graveolens, and S. alba); the same four pollen diets and three sugar diets with larvae; and finally a mixed diet of sucrose and A. graveolens pollen. A water-only (starvation) control was used for both larval development and adult longevity and fecundity. Adult lipid content was assessed as a measure of how non-prey food affects the ladybeetles' nutritional status. Larvae did not develop beyond the first instar on any of the non-prey diets, but they lived more than twice as long as on F. esculentum and sugar diets than on water. Sugar and flower diets improved A. bipunctata adult longevity (71-92 days and 10-66 days, respectively) over a pure pollen diet (6-7 days). Fecundity was nil on all non-prey diets, and within a normal range on E. kuhniella eggs. The results suggest that pure floral diets do not support A. bipunctata molting or reproduction, but flowering plants can prolong A. bipunctata larval survival and adults longevity considerably when prey are absent. Adults on sugar diets had high lipid content, indicating that sugar feeding can improve overwintering survival. The findings could be used in agroecosystem design, such as the composition of flower strips for optimal functional diversity.
