|scientific name Pissodes |
All members of this genus live in conifeous forests on and around their host plants (O'Brien, 1989).
Members of the Pissodes have been found from April until the end of September (Langor and Sperling 1995, and O'Brien 1989).
Identification most of the Pissodes weevils is difficult because of their similar morphology (Stewart and Bright, 1982). In most cases, individuals can only be identified based on their host plants and behavior. These characters are not able guarantee correct identification because of the wide range of host plants some species use.
This genus is infamous for its indistinguishable species. Morphological characters have not been useful in separating different species (Langor and Sperling, 1995). This is partly due to the great morphological variation that can exist within a species. Also, some members of Pissodes are known to interbreed, causing even more blurring of the lines between species. Therefore, taxonomists have turned to molecular characteristics to better identify species (Langor and Sperling, 1995).
While there are no conservation concerns for Pissodes weevils at this time, some of its species may cause conservation concerns in other species. In Canada, Pissodes strobi and Pissodes terminalis are major forest pests, causing millions of dollars worth of damage to the forestry industry (Smith and Sugden, 1969).
All members of Pissodes feed on pine or spruce trees. Some species feed on new branches, while for the most part Pissodes weevils feed on the root collars and boles of the tree (Smith and Sugden, 1969).
Pissodes weevils are found almost all over the globe. There are species in Europe and Asia, as well as South America (O'Brien, 1989). Most species of Pissodes are found in North America (O'Brien, 1989).
