All About Forage: Why It
WebA total of 150 full and 282 partial foraging trips of 28 bees were analyzed. For 9 bees, I recorded all flowers visited during their first (4-18, x = 10.4) foraging trips. Each of these 9 bees was observed for 24-54 (x = 36.1) foraging trips. The first experiments concerned the establishment of foraging specializations. Individual bees were WebMar 3, 2024 · A further challenge for bees foraging in farmland is exposure to agrochemicals.
