Cryphalus mangiferae
mango bark beetle
A tiny tropical bark beetle in the weevil family Curculionidae (subfamily Scolytinae) that attacks mango trees (Mangifera indica). Native to southern Asia, it has spread to tropical regions worldwide and is recognized as a vector of plant-pathogenic fungi causing mango wilt disease. In Pakistan and other regions, it poses a serious threat to mango cultivation.
Dryocoetes
Dryocoetes is a genus of bark beetles (subfamily Scolytinae) in the weevil family Curculionidae. Species are distributed across North America, Europe, Asia, and Africa. The genus includes both conifer- and hardwood-associated species, with documented hosts including fir, spruce, pine, alder, birch, beech, poplar, liquidambar, and walnut. Several species are economically significant forest pests or invasive species.
Hylastes porculus
Hylastes porculus is a crenulate bark beetle in the family Curculionidae, found in North America. The species has been documented as a vector of pathogenic fungi, including Leptographium terebrantis, Leptographium procerum, and Ophiostoma ips, to wounded roots of red pine (Pinus resinosa). Its role in transmitting these fungi implicates it in red pine decline disease.
Hylurgops palliatus
Hylurgops palliatus is a bark beetle in the family Curculionidae that colonizes coniferous trees, primarily spruce (Picea) and pine (Pinus) species. It is a secondary bark beetle, meaning it attacks weakened, dying, or recently dead trees rather than healthy ones. The species uses host-specific monoterpene chemical cues to locate and select appropriate host trees. It vectors various fungi, including ophiostomatoid species, which play roles in its ecology and tree colonization.
Pissodes nemorensis
Deodar weevil, Eastern pine weevil
Pissodes nemorensis is a univoltine true weevil in the family Curculionidae, commonly known as the deodar weevil or eastern pine weevil. It is a significant forest pest in North America, particularly in the southeastern United States, where adults and larvae feed on phloem of coniferous trees. The species acts as a vector for pitch canker fungus (Fusarium moniliforme var. subglutinans) and is associated with blue stain fungi including Leptographium procerum and Ophiostoma piceae. Seasonal activity varies geographically: southern populations are primarily active in autumn and winter, while northern populations are active in spring.
Xyleborini
ambrosia beetles, xyleborine ambrosia beetles
Xyleborini is a tribe of ambrosia beetles within the subfamily Scolytinae (Curculionidae), comprising highly specialized weevils that cultivate symbiotic fungi for food. The tribe dominates ambrosia beetle faunas across Eurasia and the Americas, with the type genus Xyleborus containing over 500 species, though this genus represents an unnatural grouping of distantly related species. Many Xyleborini are economically significant invasive pests that attack healthy trees, while others are secondary colonizers of dead or dying wood. The tribe exhibits exceptional diversity with numerous genera, many of which are small or monotypic.
