The interaction of feeding by a grass bug, Ir"bisia pacifica (Uhler), and drought stress on growth of Great Basin wildrye, Leymus cinereus (Scrih. & Merr.) Love, and intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D. R. Dewey, was studied in the greenhouse. At peak production, control plants of Great Basin wildrye had more than twice as much green leaf area per tiller than bug-i...

We tested a threshold-based bed bug (Cimex lectularius L.) management approach with the goal of achieving elimination with minimal or no insecticide application. Thirty-two bed bug infested apartments were identified. These apartments were divided into four treatment groups based on apartment size and initial bed bug count, obtained through a combination of visual inspection and bed bug monitor...

The cost and effectiveness of two bed bug (Cimex lectularius L.) integrated pest management (IPM) programs were evaluated for 10 wk. Sixteen bed bug-infested apartments were chosen from a high-rise low-income apartment building. The apartments were randomly divided into two treatment groups: diatomaceous earth dust-based IPM (D-IPM) and chlorfenapyr spray-based IPM (S-IPM). The initial median (...

In recent years, buffalograss, Buchloë dactyloides (Nuttall) Engelmann has gained popularity as a turfgrass because of its low maintenance requirement, drought tolerance, and limited pests and diseases. Within the last decade, however, the western chinch bug Blissus occiduus Barber has emerged as important pest of buffalograss. Considerable progress has been made toward identifying buffalograss...

This report describes a bug in the fragmentation code of the Madwifi driver for the Atheros chipset under the Linux kernel. The bug is due to incorrect locking of a data structure. Techniques for Linux kernel debugging are described, and a fix for the bug is presented.

Despite significant progress in software-engineering practices, software utilized for desktop and mobile computing remains insecure. At the same time, the consumer and business information handled by these programs is growing in its richness and monetization potential, which triggers significant privacy and security concerns. In response to these challenges, companies are increasingly harvestin...

The process of fixing software bugs plays a key role in the maintenance activities of a software project. Ideally, code ownership and responsibility should be enforced among developers working on the same artifacts, so that those introducing buggy code could also contribute to its fix. However, especially in FLOSS projects, this mechanism is not clearly understood: in particular, it is not know...

Objective To compare the effectiveness of the Bug Buster kit with a single treatment of over the counter pediculicides for eliminating head lice. Design Single blind, multicentre, randomised, comparative clinical study. Setting Four counties in England and one county in Scotland. Participants 133 young people aged 2-15 years with head louse infestation: 56 were allocated to the Bug Buster kit a...

Reversible debuggers have been developed at least since 1970. Such a feature is useful when the cause of a bug is close in time to the bug manifestation. When the cause is far back in time, one resorts to setting appropriate breakpoints in the debugger and beginning a new debugging session. For these cases when the cause of a bug is far in time from its manifestation, bug diagnosis requires a s...

Regression bugs occur whenever software functionality that previously worked as desired stops working, or no longer works as expected. Code changes, such as bug fixes or new feature work, may result in a regression bug. Regression bugs are an annoying and painful phenomena in the software development process, requiring a great deal of effort to localize, effectively hindering team progress. In ...
