Bed bugs, Cimex lectularius L., are one of the most difficult urban pests to control. Pest management professionals rely heavily on insecticide sprays and dusts to control bed bugs. Dust formulations are considered to provide longer residual control than sprays. However, there are no scientific data available on the comparative efficacy of the commonly used insecticide dusts. We evaluated the e...

T he most annoying aspect of software development, for me, is debugging. I don’t mind the kinds of bugs that yield to a few minutes’ inspection. The bugs I hate are the ones that show up only after hours of successful operation, under unusual circumstances, or whose stack traces lead to dead ends. Fortunately, there’s a simple technique that will dramatically reduce the number of these bugs in ...

While most debugging techniques focus on patching implementations, there are bugs whose most appropriate corrections consist in fixing the specification to prevent invalid executions—such as to define the correct input domain of a function. In this paper, we present a fully automatic technique that fixes bugs by proposing changes to contracts (simple executable specification elements such as pr...

Populations of the common bed bug, Cimex lectularius, have recently undergone explosive growth. Bed bugs share many important traits with triatomine insects, but it remains unclear whether these similarities include the ability to transmit Trypanosoma cruzi, the etiologic agent of Chagas disease. Here, we show efficient and bidirectional transmission of T. cruzi between hosts and bed bugs in a ...

Software testing has been reported as one of the main responsible for quality assurance in a software project. In this effect, a series of techniques, methods, and tools can be found in the literature. In this work, we propose an approach to manage bugs using multiple software visualization. We developed an eclipse-based plug-in to report bugs. As a result of this activity, the collected bugs m...

Bugs in network hardware can cause tremendous problems. However, programmable devices have the potential to provide greater visibility into internal behavior of devices, allowing us more quickly find and identify In this paper, we a taxonomy data plane bugs, use derive Portable Test Architecture (PTA) which offers essential abstractions for testing on variety devices. PTA is implemented with no...

Host location in bed bugs is poorly understood. Of the primary host-associated cues known to attract bed bugs - CO2, odors, heat - heat has received little attention as an independent stimulus. We evaluated the effects of target temperatures ranging from 23 to 48°C on bed bug activation, orientation and feeding. Activation and orientation responses were assessed using a heated target in a circu...

The effectiveness of a trap for triatomines baited with yeast cultures has been previously demonstrated in laboratory assays. We report results from assays testing yeast-traps for Triatoma infestans performed under natural climatic conditions. All assays were conducted at experimental chicken-coops colonised by bugs, situated at an endemic area for Chagas disease in Argentina. Two different mod...
