Symbiosis and competition: complex interactions among beetles, fungi, and mites
These relationships may be best understood by considering the manner in which symbioses vary with time and resources, and the degree to which other species may affect interactions among symbionts.
Antagonisms, mutualisms and commensalisms affect outbreak dynamics of the southern pine beetle
This work examined the effects of two linked mutualisms on the population dynamics of a beetle that exhibits outbreak dynamics, finding that reproductive rates of Tarsonemus, O. minus, and beetles covaried in a manner consistent with strong indirect interactions between organisms.
Alarm pheromones of the ant atta texana.
A key to the mites associated with flying Ips typographus in South Germany
A key identifies 32 species of mites associated with flying Ips typographus collected from nondestructive pheromone traps in South Germany. Fifteen species were judged phoretic because they were
Mites associated with Southern Pine Bark Beetles in Allen Parish, Louisiana
Ninety-six species of mites were associated with the southern pine beetle and allied scolytids in an outbreak area in Allen Parish, La. The complex was evaluated to ascertain which species may be of
Strong indirect interactions of Tarsonemus mites (Acarina: Tarsonemidae) and Dendroctonus frontalis (Coleoptera: Scolytidae)
Tarsonemus mites close a loop of species interactions that includes a commensalism (mites and beetles), a mutualism ( mites and O. minus), asymmetric competition (O. minus and mycangial fungi), and another mutualism(s) (mycangia fungi and beetles).
Mutualism and Antagonism: Ecological Interactions Among Bark Beetles, Mite and Fungi
This work focuses on bark beetles and their associated organisms, in particular, on the relationship between the southern pine beetle and its associates in coniferous trees of the southern USA.
Transportation of phytopathogenic fungi by the bark beetle Ips sexdentatus Boerner and associated mites
The bark beetle Ips sexdentatus carries several types of conidiospores and ascopores in the pronotal punctures located around the setae on the sides of the pronotum. For swarming beetles, some of the
Relative Abundance of Southern Pine Beetle Associates in East Texas
More than 90 species of insects were identified in bolts taken from east Texas loblolly pines infested by the southern pine beetle, Dendroctonus frontalis Zimmermann and by Ips engraver beetles
