Alternative Prey and Artificial Diet of the Multicolored Asian Lady Beetle Harmonia axyridis: A Review [PDF]

Insects
As an important natural enemy insect, Harmonia axyridis has significant biological control effects on a variety of pests such as aphids in agroforestry ecosystems. The large-scale application of H. axyridis has long been limited by the unstable supply of

Alternative Prey and Predator Interference Mediate Thrips Consumption by Generalists [PDF]

Frontiers in Ecology and Evolution, 2022
Generalist predators’ complex feeding relationships make it difficult to predict their contribution to pest suppression. Alternative prey can either distract predators from attacking pests, weakening biocontrol, or provide food that support larger ...

Small prey fight back: post-capture defences shape prey–predator size relationships [PDF]

Scientific Reports
Size relationships between prey and predators are a key topic in ecology. A positive correlation often exists between the sizes of prey and predators. Although predators can consume much smaller prey, some preferentially target larger prey and avoid very

Vulnerability of the mosquito larvae to the guppies (Poecilia reticulata) in the presence of alternative preys [PDF]

Journal of Vector Borne Diseases, 2008
Background & objectives: The predatory potential of the larvivorous fishes can be affected by the presence of alternative preys. In the present study the predation pattern of the sewage dwelling Poecilia reticulata (Peters 1872) on the larvae of Culex ...

Pronounced Seasonal Diet Diversity Expansion of Golden Eagles (Aquila chrysaetos) in Northern Greece during the Non-Breeding Season: The Role of Tortoises

Diversity, 2022
Golden Eagles are resident in Greece and known to feed mainly on tortoises when breeding. However, information on alternative prey is scarce, especially during the tortoise brumation, that roughly coincides with the eagles’ non-breeding season.

Direct and indirect effects of banker plants on population establishment of Harmonia axyridis and aphid control on pepper crop

Frontiers in Plant Science, 2022
Banker plant systems increase biological pest control by supporting populations of natural enemies, i.e., using non-pest arthropod species as alternative prey.

Alternative prey mediate intraguild predation in the open field

Pest Management Science, 2022
AbstractBACKGROUNDGeneralist predators that kill and eat other natural enemies can weaken biological control. However, pest suppression can be disrupted even if actual intraguild predation is infrequent, if predators reduce their foraging to lower their risk of being killed.

FUNCTIONAL RESPONSES: A QUESTION OF ALTERNATIVE PREY AND PREDATOR DENSITY [PDF]

Ecology, 2007
Throughout the study of ecology, there has been a growing realization that indirect effects among species cause complexity in food webs. Understanding and predicting the behavior of ecosystems consequently depends on our ability to identify indirect effects and their mechanisms.

An alternating active-dormitive strategy enables disadvantaged prey to outcompete the perennially active prey through Parrondo’s paradox [PDF]

BMC Biology, 2021
Abstract Background Dormancy is widespread in nature, but while it can be an effective adaptive strategy in fluctuating environments, the dormant forms are costly due to the inability to breed and the relatively high energy consumption.

A simple predator–prey model of exploited marine fish populations incorporating alternative prey [PDF]

ICES Journal of Marine Science, 1996
A simple two-species population model in which the predator is partially coupled to the prey is developed. The model is an extension of traditional two-species models but less complex than a three-species system. The growth rate of the predator depends upon predation on the modeled and alternate prey; this formulation provides greater realism in ...
