Colonization of the rhizosphere, rhizoplane and endorhiza of garlic (Allium sativum L.) by strains of Trichoderma harzianum and their capacity to control allium white-rot under field conditions
The ecological behavior of Trichoderma strains should be included as a criterion for strain selection for biological control purposes, as high early endorhizal colonization was positively correlated with the BCA capacity of the strains. Expand
Insecticide resistance of adults and nymphs of Asian citrus psyllid populations from Apatzingán Valley, Mexico.
Resistance management programmes that include crop sanitation, use of biological and cultural control practices, and rotation of insecticide classes should be established, particularly in areas where D. citri has developed resistance to malathion and chlorpyrifos. Expand
Landscape Analysis of Adult Codling Moth (Lepidoptera: Tortricidae) Distribution and Dispersal within Typical Agroecosystems Dominated by Apple Production in Central Chile
ABSTRACT We analyzed the spatial distribution and dispersal of codling moth, Cydia pomonella (L.), adults within two heterogeneous agroecosystems typical of central Chile: commercial apple, MalusExpand
Landscape composition modulates population genetic structure of Eriosoma lanigerum (Hausmann) on Malus domestica Borkh in central Chile.
The woolly apple aphid, Eriosoma lanigerum (Hausmann), an important pest of apple orchards worldwide, was collected on apple trees from different locations in a 400 km north-south transect trough central Chile to determine if there was population structure, diversity and flow. Expand
Abstract Four commercial sex pheromones and virgin females were tested as attractants for male fall armyworm (FAW), Spodoptera frugiperda with Scentry Heliothis traps in sorghum fields in Chiapas,Expand
Niche breadth and interspecific competition between Doryctobracon crawfordi and Diachasmimorpha longicaudata (Hymenoptera: Braconidae), native and introduced parasitoids of Anastrepha spp. fruit
The results suggest that simultaneous augmentative release of these two species would result in substantial competition, however, because D. crawfordi is naturally found at greater densities than D. longicaudata at high elevations, releases in such areas might yield better results than releases of its otherwise superior competitor.

Superparasitism strategies by a native and an exotic parasitoid species attacking the Mexican fruit fly, Anastrepha ludens (Diptera: Tephritidae)
An understanding of the superparasitism strategy adopted by parasitoid species could be of great interest to augmentative biological control programmes because the mass rearing of natural enemies could be negatively or positively affected by this condition. Expand
