Determining the vulnerability of Mexican pine forests to bark beetles of the genus Dendroctonus Erichson (Coleoptera: Curculionidae: Scolytinae)

Effects of biotic disturbances on forest carbon cycling in theUnitedStates andCanada

“…For a small number of economically important insect or pathogen species in the United States and Canada, predictive models of a specific climate driver (e.g., winter temperature) have been developed (e.g., Thomson et al, 1984;Wilder, 1999;Hansen et al, 2001;Logan et al, 2003;Tran et al, 2007;Gray, 2008;Stone et al, 2008). However, less is known about most pathogens, and biotic disturbance agents in some North American regions, especially Mexico, are little understood even though some may be quite important (Salinas-Moreno et al, 2010). Full integration of forest stand conditions, climate drivers of host condition/ susceptibility and insect/pathogen population dynamics, and host/biotic disturbance agent interactions that could allow for more complete simulations has yet to be accomplished for any insect or pathogen.…”

Bark beetle pests in an altitudinal gradient of a Mexican managed forest

“…Bark beetle incidence and damage has increased in recent years throughout the world in temperate forests (FAO, 2010;Marini et al, 2012;Salinas-Moreno et al, 2010). Northern countries in America (Bentz et al, 2010;Creeden et al, 2014;FAO, 2010;Weed et al, 2013) and Eurasia (Schelhaas et al, 2003) are experiencing severe damage every year in locations where bark beetles were previously scarce or even non-existent.…”

Bark Beetle Species (Coleoptera: Curculionidae: Scolytinae) and their Vertical Distribution onPinus greggiiduring an Outbreak in the Sierra Madre Oriental of Mexico

“…The species richness and geographic complexity of bark beetles on pines in Mexico have resulted in outbreaks with site-specific variations in the species of attacking bark beetles and in the severity of damage to pine hosts (Salinas-Moreno et al 2010). There was a recent massive outbreak of bark beetles near the towns of Valle Verde and San Juan de los Duran in the municipality of Jalpan between 21 o 27' to 21 o 33' N, 99 o 08' to 99 o 15' W in the Sierra Gorda mountain system in the State of Querétaro, Mexico.…”

“…The multiple species association during early attack of P. greggii has not been reported previously. In fact, P. greggii is not considered a preferred host species of the genus, and the central region of the Sierra Madre Oriental is classified as low risk for outbreaks of Dendroctonus (Salinas-Moreno et al 2010). Also, according to Wood (1982) and Cibrián et al (1995), D. valens, Hyla.…”
