Many species of fungi are closely allied with bark beetles, including many tree pathogens, but their species richness and patterns of distribution remain largely unknown. We established a protocol for metabarcoding of fungal communities directly from total genomic DNA extracted from individual beetles, showing that the ITS3/4 primer pair selectively amplifies the fungal ITS. Using three specime...
DNA-DNA hybridization was used to discover the extent of single-copy DNA similarity among 13 species of herons and one ibis. Genetic distances among taxa were summarized as Tm values in a folded matrix. From this matrix, trees with the same branching pattern were constructed by least squares under one of two assumptions: (1) that sister branches are equal in length and (2) that sister branches ...
The response of bark beetle predators and woodboring beetles to the bark beetle anti-aggregation pheromone, verbenone, was tested in the field with multiple-funnel traps baited with attractant kairomones. Catches of the predators Thanasimus undatulus (Say), Enoclerr~~ sphegeus (F.) , Erwclaus lecontei (Wolcott) (Coleoptera: Cleridae) , and hcono tu .~ complex LeConte (Coleoptera: Colydiidae) de...
INTRODUCTION Hypodermosis is an ectoparasitic disease of cattle caused by Hypoderma lineatum and Hypoderma bovis. It is an important health problem of cattle, leading to considerable economic losses. There are various factors that are involved in the spread of this disease such as herd size, location, temperature, humidity, and precipitation. METHODOLOGY Blood samples from 112 herds were coll...
Ophiostoma galeiforme was described first in 1951 from Larix kaempferi in Scotland, where it was found to be associated with the bark beetles Hy-lurgops palliatus, Dryocoetes autographus, and the ambrosia beetle Trypodendron lineatum. The taxonomy of this fungus has been uncertain because of a lack of sexual structures on the type specimen and contamination of a preserved ex-type culture. The a...
