Abstract Nymphs of Perillus bioculatus F., a specialist pentatomid predator of the Colorado potato beetle, Leptinotarsa decemlineata (Say), are smaller than comparable instars of their prey. In laboratory experiments, P. bioculatus fed small prey exhibited greater capture success, increased survivorship, and faster development to adulthood than individuals fed large prey. An increase of potato beetle prey stage by one instar lowered capture success and survival by 82 and 80%, respectively… Expand
Prey size affects the costs and benefits of group predation in nymphs of the predatory stink bug Andrallus spinidens (Heteroptera: Pentatomidae)
TLDR
The results suggest that group predation by A. spinidens nymphs is advantageous for individual members because it enables each member to hunt larger prey that could not be hunted alone, however, when group size was large or prey size was small, grouppredation increased competition among group members.

Prey suitability of Thrips palmi (Thysanoptera: Thripidae) and Tetranychus kanzawai (Acari: Tetranychidae) for the development and reproduction of Wollastoniella rotunda (Hemiptera: Anthocoridae)
TLDR
Findings indicated that T. kanzawai and T. palmi are both suitable prey species for W. rotunda, and suggest the potential for application of the predator as a biological control agent against both of these pest species. Expand
Fitness consequences of sibling egg cannibalism by neonates of the Colorado potato beetle, Leptinotarsa decemlineata
TLDR
A simulation demonstrated that when the mortality risk is high, decreased development time due to cannibalism can reduce this risk sufficiently to balance the inclusive fitness loss of eating a single half-sibling. Expand
Does the aggressiveness of the prey modify the attack behavior of the predator Supputius cincticeps (Stål) (Hemiptera, Pentatomidae)?
TLDR
Test if the attack behavior and predation success of S. cincticeps were affected by prey species, which possesses desirable attributes as a natural control agent and in biological control programs, and changes with the prey species offered. Expand
Large size as an antipredator defense in an insect
TLDR
An evolutionary scenario whereby a change in feeding behavior toward vertebrate-toxic plants served as an evolutionary breakthrough, setting in motion the subsequent evolution of increased chemical defense and large body size in lubbers is proposed. Expand
Maternally induced intraclutch cannibalism: an adaptive response to predation risk?
TLDR
It is shown that mothers experiencing predation risk increase production of unviable trophic eggs, which assures provisioning of an egg meal to the newly hatched offspring, and experimentally demonstrated that egg cannibalism reduces L. decemlineata vulnerability to predation by improving larval nutritional condition and expression of anti-predator responses.

Consumption of Immature Stages of Colorado Potato Beetle by Chrysoperla Carnea (Neuroptera: Chrysopidae) Larvae in the Laboratory
TLDR
The authors' laboratory assays highlight a potential for lacewing larvae to control CPB immature stages with a greater efficiency on young CPB larval stages, and Fields assays are however needed to confirm efficiency of this CPB natural enemy under field conditions. Expand
Multi–predator Effects Produced by Functionally Distinct Species Vary with Prey Density
TLDR
Examining the potential for functional differences among predator species to promote suppression of an insect pest suggests that multiple predator species may only provide greater biological control than single species in systems where prey is limiting. Expand

Facilitated predation through interaction between life stages in the stinkbug predatorperillus bioculatus (Hemiptera: Pentatomidae)
TLDR
The function of communal feeding in two-spotted stinkbug Perillus bioculatus is discussed, as well as the potential for greater impact on prey density that may be expected from tolerance to opportunistic feeding by conspecifics in slightly gregarious predators. Expand
Comparison of Perillus bioculatus and Podisus maculiventris (Hemiptera:Pentatomidae) as potential control agents of the Colorado potato beetle (Coleoptera:Chrysomelidae).
In laboratory and microplot consumption tests, spined soldier bug, Podisus maculiventris (Say), ate at least as many Colorado potato beetle, Leptinotarsa decemlineata (Say), eggs and larvae as didExpand
Effects of prey density, prey instar, and patch size on the development of the predatory mosquito, Toxorhynchites towadensis
TLDR
It is suggested that a small surface container containing prey of mixed instars and high density is suitable for development of predators. Expand
Prey preference in stoneflies: a comparative analysis of prey vulnerability
TLDR
Values increased with increasing size of the predator, and inclusion of the C/A term indicated that predators would obtain greater reward from small relative to large prey, and from dipterans relative to mayflies. Expand

TLDR
The data indicate that inoculative releases of stinkbug predators for suppression of Colorado potato beetle populations could be an important component of an integrated management program. Expand

TLDR
While the behaviour of ant-lion larvae is consistent with an energy maximizer strategy it is concluded that the approach is of limited value in this instance. Expand
Prey Preference by the StinkbugPerillus bioculatus,a Predator of the Colorado Potato Beetle
TLDR
Results confirm specialization of P. bioculatus towardCPB or related prey and suggest genetically inheritable as well as maternally reinforcible affinity toward CPB prey, which can be lowered by rearing parents on alternative prey, increasing their chances of survival when alternative prey must be relied upon.

Impact of Perillus bioculatus on the Colorado potato beetle and plant damage.
TLDR
Given the number and life stages of the predators and defoliators, the amount of prédation and defoliation was predicted and the yield loss was estimated. Expand
