TLDR
Frontalure contained emerging broods of southern pine beetle within active infestations when used as a bait on all host and non-host trees within the infestation.Abstract:
Frontalure contained emerging broods of southern pine beetle within active infestations when used as a bait on all host and non-host trees within the infestations. The attractant was successful in redistributing populations of the southern pine beetle and the predator, Thanasimus dubius (F.), within the infestations. The attractant also prevented new trees from being mass attacked and contained adult beetles within the infestation.read more

Behavioral mechanisms involved in reducing competition in bark beetles
TL;DR: Bark beetles feed and reproduce in the phloem/cambium tissue of trees where severe competition between individuals of the same and different species significantly reduces their reproductive success and individuals that can avoid competition whenever possible by means of genetically controlled behavioral mechanisms are naturally selected.

TL;DR: Electro-physiological studies revealed that antennal olfactory receptor cells were significantly more responsive to (1S, 5R)-(−)-frontalin than to ( 1R, 5S)-(+)- frontalin, which suggests that each cell possesses at least two types of enantiomer-specific acceptors.

Selective manipulation of predators using pheromones: responses to frontalin and ipsdienol pheromone components of bark beetles in the Great Lakes region
TL;DR: One proposed approach to improving biological control of bark beetles is to manipulate predator movement using semiochemicals, but selective manipulation is impeded by attraction of both predators and pests to bark beetle pheromones.
Potential for Biological Control of Dendroctonus and Ips Bark Beetles
TL;DR: Biological control can be made more effective in theory and practice by employing new parasite (predator) associations than by employing "old" associations typical of classical biocontrol.
