To manage agroecosystems for multiple ecosystem services, we need to know whether the
management of one service has positive, negative, or no effects on other services. We do …

Plants can respond to feeding or egg deposition by herbivorous arthropods by changing the
volatile blend that they emit. These herbivore-induced plant volatiles (HIPVs) can attract …

the secondary metabolism of living organisms in different biotopes. They are relatively …

Among herbivorous insects with a complete metamorphosis the larval and adult stages
usually differ considerably in their nutritional requirements and food ecology. Often, feeding …

The majority of predators and parasitoids require non-prey food as part of their diet. The
availability of suitable non-prey food can impact predator–prey and parasitoid–host …

Background Plants in over one hundred families in habitats worldwide bear extrafloral

ecological services, including conservation of native flora and fauna, enhancement of …

Repeated mass introductions of natural enemies have been widely used as a biological
control strategy in greenhouse systems when the resident population of natural enemies is …

Companion planting is a well-known strategy to manage insect pests and support a natural
enemy population through vegetative diversification. Trap cropping is one such type of …

The use of artificial food sprays to increase the abundance and impact of natural enemies of
arthropod pests has been recognized for over 40 years. Nevertheless, artificial food sprays …
