citrus mealy bug, planococcus citri (risso)is one of the most common and well knownpest insects of ornamentals. coleus, solenostemon scutellarioides (l.)codd is a suitable host ofthe mealybugs. mealybug destroyer, cryptolaemus montrouzieri mulsant (coleoptera:coccinellidae) is a polyphagous predatory coccinellid, employed in biological controlprograms against citrusmealy bug. the present work w...

Open Source Software (OSS) uses open bug repository during development and maintenance, so that both developer and user can reports bugs that they have found. These systems are generally called as bug tracking system or bug repositories. Bug tracking system is open bug repository that is maintained by open source software organizations to track their bugs. In OSS bug reports from all over the w...

Context: Bug report assignment, namely, to assign new bug reports to developers for timely and effective bug resolution, is crucial for software quality assurance. However, with the increasing size of software system, it is difficult to assign bugs to appropriate developers for bug managers. Objective: This paper propose an approach, called KSAP (K-nearest-neighbor search and heterogeneous prox...

Tracking of a reported bug for fixing is a fascinating area of research in software engineering. Many open source, free and commercial bug tracking tools have been developed and are currently under development. The industry needs criteria to select the best tool among the available set of tools that will help in fixing and tracking the progress of bug fixes. In this paper, we use BugZilla, Jira...

We describe a method of creating tools to find bugs in software that is driven by the analysis of previously fixed bugs. We present a study of bug databases and software repositories that characterize commonly occurring types of bugs. Based on the types of bugs that were commonly reported and fixed in the code, we determine what types of bug finding tools should be developed. We have implemente...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

With a great number of software products that have been developed, bug fixing is difficult due to a large number of submitted bug reports each day. Sometimes developers usually describe the same errors in the different bug reports, these bug reports are called duplicate bug reports, the increasing number of duplicates lead to a large amount of time and effort for identifying and analyzing bug r...

Bugs are the inevitable part of a software system. Nowadays, large software development projects even release beta versions of their products to gather bug reports from users. The collected bug reports are then worked upon by various developers in order to resolve the defects and make the final software product more reliable. The high frequency of incoming bugs makes the bug handling a difficul...

Benchmarking provides an effective way to evaluate different tools. Unfortunately, so far there is no good benchmark suite to systematically evaluate software bug detection tools. As a result, it is difficult to quantitatively compare the strengths and limitations of existing or newly proposed bug detection tools. In this paper, we share our experience of building a bug benchmark suite called B...

Bug fix is an important and challenging task in software development and maintenance. Bug fix is also a dangerous change, because it might induce new bugs. It is difficult to decide whether a bug fix is safe in practice. In this paper, we conducted an empirical study on bug inducing analysis to discover the types and features of fault prone bug fixes. We use a classical algorithm to track the l...
