Generalist predator guilds play a prominent role in structuring insect communities and can contribute to limiting population sizes of insect pest species. A consequence of dietary breadth, particularly in predatory insects, is the inclusion of low-quality, or even toxic, prey items in the predator's diet. Consumption of low-quality prey items reduces growth, development, and survival of predato...

15 صفحه اولIngestion of Ice-nucleating Active Bacteria Increases the Supercooling Point of the Lady Beetle Hippodamia Convergens
Regulation of the temperature at which insects freeze is a critical factor in their overwintering survival. Although the role of ice-nucleating active bacteria in promoting frost-damage in plants is well known, their interaction with other organisms has not been described. In winter. many freeze-susceptible insects avoid freezing by lowering the temperature at which their body fluids spontaneou...
متن کاملInfluence of aphid honeydew on the foraging behavior of <i>Hippodamia convergens</i> larvae
1. Environmental cues associated with prey are known to increase predator foraging efficiency. Ladybird larvae are major predators of aphids. The sugary excretion of aphids (honeydew) has been proposed to serve as a prey-associated cue for ladybird larvae. 2. Ladybird larvae are regularly found on the ground moving between plants or after falling off plants. The use of prey-associated cues woul...
