Soybean is an important food crop, and insect integrated pest management (IPM) is critical to the sustainability of this production system. In recent years, the introduction into the United States of the kudzu bug currently identified as Megacopta cribraria (F.), poses a threat to soybean production. The kudzu bug was first discovered in the state of Georgia, U.S. in 2009 and since then has spr...

Since 1988, cucurbit crops, particularly watermelon, cantaloupe, and squash, grown in Oklahoma and Texas have experienced devastating losses from cucurbit yellow vine disease (CYVD), caused by the phloem-limited bacterium Serratia marcescens Bizio. Squash bug, Anasa tristis (De Geer), is a putative vector of the pathogen. In 2000-2001, overwintering populations of squash bug collected from DeLe...

In the southeast United States, a field of peanuts, Arachis hypogaea L., is often closely associated with a field of cotton, Gossypium hirsutum L. The objective of this 4-yr on-farm study was to examine and compare the spatiotemporal patterns and dispersal of the southern green stink bug, Nezara viridula L., and the brown stink bug, Euschistus servus (Say), in six of these peanut-cotton farmsca...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 4. The 4-year average for the different fertilizer backgrounds indicated that the least total grain damage by cereal bug larvae was in the block with organic-mineral fertilizer, 5.6 %. Damage in the blocks without fertilizer and with only organic fertilizer was 5.9 and 6.0 %, respectively. Total damage was 4.2–4.9 % in seed with a score of 2, w...

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 ...
