Research ArticleOpen accessEvery word in the titleAutomated Fall Armyworm (Spodoptera frugiperda, J.E. Smith) Pheromone Trap Based on Machine LearningSimon H. Chiwamba, Jackson Phiri, Philip O.Y. Nkunika et al.Maize is the main food crop that meets the nutritional needs of both humans and livestock in the sub-Saharan African region. Maize crop has in the recent past been threatened by the fall armyworm (Spodoptera frugiperda, J.E Smith) which has caused considerable maize yield losses in the region. Controlling this pest requires knowledge on the time, location and extent of … …Journal of Computer Science, Vol. 15, Issue 12 · 19 Dec 2019 · 8,364 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrated Protection of Tomato Crops against Tuta absoluta in Open Ground Conditions in the South-East Part of KazakhstanA. Adilkhankyzy, K. A. Alpysbayeva, B. Nurmanov et al.There is a need to develop strategies for the protection of tomato crops that would provide high-quality produce safe for the consumer without environmental pollution. The objective of the study is to deploy an integrated system for the protection of open-field tomato crops from Tuta absoluta using biological agents (Bracon hebetor Say., Trichogramma, biopreparations, pheromone traps) and devices in the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 16 Dec 2022 · 5,375 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnt Colony Optimization for Capacitated Vehicle Routing ProblemW. F. Tan, L. S. Lee, Z. A. Majid, H. V. SeowProblem statement: The Capacitated Vehicle Routing Problem (CVRP) is a well-known combinatorial optimization problem which is concerned with the distribution of goods between the depot and customers. It is of economic importance to businesses as approximately 10-20% of the final cost of the goods is contributed by the transportation process. Approach: This problem was tackled using an Ant Colony Optimization … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 10,043 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBehaviour Patterns of the Pine Processionary Moth (Thaumetopoea wilkinsoni Tams; Lepidoptera: Thaumetopoeidae)Ahmad Houri, Dany DoughanThaumetopoea wilkinsoni is a serious pest of pine trees, especially the wide-spread Pinus brutia. This infestation has a significant economic impact both in the loss of forest wood growth and in medical expenses for treating related human diseases. This paper presents a detailed study of the behaviour patterns of the moth stage in an attempt to identify best control methods. … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 8,695 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified ACS Centroid Memory for Data ClusteringAyad Mohammed Jabbar, Ku Ruhana Ku-Mahamud, Rafid SagbanAnt Colony Optimization (ACO) is a generic algorithm, which has been widely used in different application domains due to its simplicity and adaptiveness to different optimization problems. The key component that governs the search process in this algorithm is the management of its memory model. In contrast to other algorithms, ACO explicitly utilizes an adaptive memory, which is important to … …Journal of Computer Science, Vol. 15, Issue 10 · 11 Oct 2019 · 7,641 accessesView PDFCite
InvestigationOpen accessIn the abstractComparison Analysis of Species Composition of Entomopathogenic Fungi Isolated from Bark Beetles (Coleoptera: Scolytidae)Rauza Abdukerim, Georgy Lednev, Miloš Trýzna et al.The monitoring outbreaks of bark beetles, flight activity of imago and development of larvae were conducted with pheromone traps and trap logs. We found more than 50 dead adults with symptoms white muscardine from several points under the bark. Healthy adults of Ips typographus without any pathogenic symptoms collected from pheromone traps and trap logs under bark in the forest … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 18 Jan 2018 · 7,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault Tolerance Grid Scheduling with Checkpoint Based on Ant Colony SystemSaufi Bukhari, Ku Ruhana Ku-Mahamud, Hiroaki MorinoTask resubmission and checkpoint are among several popular techniques used in providing fault tolerance in grid computing. However, due to the lack of side-by-side comparison, it is not certain of the best technique that would not degrade the system performance in addition to providing fault tolerance capability. This study proposed Dynamic ACS-based Fault Tolerance in grid computing using resubmission to … …Journal of Computer Science, Vol. 13, Issue 8 · 1 Sep 2017 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Colony Optimization for Container Loading ProblemC. N. Yap, L. S. Lee, Z. A. Majid, H. V. SeowProblem statement: The Container Loading Problem (CLP) considers packing a subset of given rectangular boxes into a rectangular container of fixed dimensions in the most optimum way. This was very important in the logistics industries and warehousing problems, since the cost can be reduced by increasing the space utilization ratio. Approach: This problem was solved in a two-phased Ant Colony … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 20 Mar 2012 · 8,561 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedding Malaysian House Red Ant Behavior into an Ant Colony SystemZ. A. Othman, H. M. Rais, A. R. HamdanProblem statement: Ant Colony System (ACS) is the most popular algorithm used to find a shortest path solution in Traveling Salesman Problem (TSP). Several ACS versions have been proposed which aim to achieve an optimum solution by adjusting pheromone levels. However, it still has a room on an improvement. This research aims to improve the algorithm by embedding individual Malaysian … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,961 accessesView PDFCite
