Apple, Pest and Natural Enemy Effects Under Tabm Control Tactics, 1996

Natural enemy interactions constrain pest control in complex agricultural landscapes.

Biological control of pests by natural enemies is a major ecosystem service delivered to agriculture worldwide. Quantifying and predicting its effectiveness at large spatial scales is critical for increased sustainability of agricultural production. Landscape complexity is known to benefit natural enemies, but its effects on interactions between natural enemies and the consequences for crop dam...

Evaluation of Pest Management Tactics for Organic Apple Production

In New York State, a large number of both native and introduced insect and mite species attack apples grown in commercial apple orchards. Control of this pest complex is particularly challenging, because unlike the more arid apple production regions on the West Coast, apple orchards in N.Y. are commonly in close proximity to semi-wooded areas having an abundance of wild apple and hawthorn speci...

Theoretical Study of Pest Control Using Stage Structured Natural Enemies with Maturation Delay: A Crop-Pest-Natural Enemy Model

In the natural world, there are many insect species whose individual members have a life history that takes them through two stages, immature and mature. Moreover, the rates of survival, development, and reproduction almost always depend on age, size, or development stage. Keeping this in mind, in this paper, a three species crop-pest-natural enemy food chain model with two stages for natural e...

Dual Defense: Pest-resistant Turf and Natural Enemy Interactions

Pest control of aphids depends on landscape complexity and natural enemy interactions.

Aphids are a major concern in agricultural crops worldwide, and control by natural enemies is an essential component of the ecological intensification of agriculture. Although the complexity of agricultural landscapes is known to influence natural enemies of pests, few studies have measured the degree of pest control by different enemy guilds across gradients in landscape complexity. Here, we u...
