Harlequin bug, Murgantia histrionica (Hahn), is a pest of cole crops in the USA. Laboratory toxicity assays revealed that the neonicotinoid insecticides imidacloprid, thiamethoxam, dinotefuran, and clothianidin are toxic to harlequin bug nymphs; LC50 = 0.57, 0.52, 0.39, and 0.39 ppm, respectively. Field experiments were conducted to evaluate the efficacy of these insecticides over time when app...

" Pre-release efficacy assessment of biological control of Chinese privet was evaluated by lace bug inoculation on privet. " 15 Pairs of adult inoculation significantly reduced leaf biomass by more than 59% compared to 0 and 3 lace bug pairs, while 3 and 9 pairs had no effect. " The percentage of leaf feeding damage is positively correlated with the density of lace bugs inoculated. " Increasing...

Recently, ELRA initiated the development of a bug report mechanism for the speech databases in its catalogue. This paper reports on the framework of this new service and its practical implementation. Topics dealt with are bug administration, communication with the reporters, formal error listings, corrections of databases, and the release of corrective patches and updated versions of databases....

A Heisenbug is a computer bug that disappears or alters its characteristics when we try to apply standard debugging techniques to catch the error. One example is a bug that occurs in a program compiled for optimized execution (non-debugging mode), but not in the same program compiled to run under debugmode. Executing program in debug-mode often cleans memory before the program starts, and can e...

Machine learning techniques can be used to analyse data from different perspectives and enable developers to retrieve useful information. Machine learning techniques are proven to be useful in terms of software bug prediction. In this paper, a comparative performance analysis of different machine learning techniques is explored for software bug prediction on public available data sets. Results ...

It is important that information provided in bug reports relevant and complete order to help resolve bugs quickly. However, often such trickles developers after several iterations of communication between Developers reporters. Poorly designed tracking systems are partly blame for this exchange being stretched over time. Our paper addresses the concerns by proposing four broad directions enhance...

The public nature of discussion in open source projects provides a valuable resource for understanding the mechanisms of open source software development. In this paper we explore how open source projects address issues of usability. We examine bug reports of several projects to characterise how developers address and resolve issues concerning user interfaces and interaction design. We discuss ...

The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-seaso...
