Testing the resource concentration hypothesis with tarnished plant bug on strawberry: density of hosts and patch size influence the interaction between abundance of nymphs and incidence of damage

摘要: . 1. Attributes of patches with strawberry plants were manipulated experimentally to assess the impact patch size and host density on abundance tarnished plant bug (Hemiptera: Miridae) incidence fruit damage. 2. The nymphs per inflorescence increased for some but not all generations bug, providing partial support resource concentration hypothesis, while emphasising importance replicating experiments across several herbivore. 3. Increasing increasing did translate into a high damage, which may be due relatively low feeding in numerous fruits perimeter-to-area ratio small resulting proportion damaged fruits. 4. decreasing suggests that exhibit saturating functional response fruits. Functional responses herbivores critical yet overlooked component influences interactions between insects their plant. In particular, concentrated resources result numbers sill have negligible influence damage and/or fitness.
