Conventional thought would suggest that there are sufficient venues for the publication of entomological scientific inquiries and begs the question: “Why begin another outlet for insect-related scientific comment?” The open access journal Insects is a response to the pressing global thirst for information and an acknowledgement of the potential of electronic media. Dissemination of information is critical to growing the global knowledge base through easy and open access. This new journal is a celebration of the diversity of insects, other arthropods, and their relationship with humans in our shared environment. [...] Full article

White pine weevil (Pissodes strobi, Peck.) is a native forest insect pest in the Pacific Northwest of North America that attacks species of spruce (Picea spp.) and pine (Pinus spp.). Young Sitka spruce [Picea sitchensis (Bong.) Carr.] trees are particularly susceptible to weevil attack. Pockets of naturally occurring Sitka spruce resistance have been identified in high weevil hazard areas in coastal British Columbia. In this study, we characterize behavioral, physiological and reproductive responses of weevils to an extremely resistant Sitka spruce genotype (H898) in comparison to a highly susceptible genotype (Q903). The experiments relied on a large number of three-year-old clonally propagated trees and were therefore restricted to two contrasting Sitka spruce genotypes. When exposed to resistant trees, both male and female weevils were deterred during host selection and mating, females showed delayed or reduced ovary development, and successful reproduction of weevils was prevented on resistant trees.
