This study develops a mathematical model for describing the dynamics of the banana-nematodes and its pest detection method to help banana farmers. Two criteria: the mathematical model and the type of nematodes pest control system are discussed. The sensitivity analysis, local stability, global stability, and the dynamic behavior of the mathematical model are performed. Further, we also develop and discuss the optimal control mathematical model. This mathematical model represents various modes of management, including the initial release of infected predators as well as the destroying of nematodes. The theoretical results are shown and verified by numerical simulations.

The author has designed a visual workbench to realize that the rim can rotate with the workbench. Meanwhile, the linear CCD camera records the rim’s circumference. The paper has explored the measurement method of getting the rim valve hole position using machine vision. The system can calculate the position of rim-hole and control the servo motor by image processing, characteristic recognizing and measuring to locate the position of wheel-hole automatically. And the paper has verified the accuracy of the method by experiments.

<p>El chinche de encaje, Corythucha gossypii (Fabricius) (Hemiptera: Tingidae), es un insecto plaga del algodón, pero ha sido reportado en más de veinticuatro hospederos, incluyendo higuerilla (Ricinus communis L). El objetivo de este trabajo fue evaluar si esta plaga disminuye el periodo de vida útil de las hojas, establecer la superficie de muestreo de la hoja que mejor representa las poblaciones de esta plaga y la eficacia de seis insecticidas para su control en higuerilla. La vida útil de las hojas fue negativamente influenciada por la presencia del insecto plaga; a mayor número inicial de insectos, menor fue el tiempo para la pérdida de hojas. La superficie del envés fue la que mejor representó la población de C. gossypii con un promedio ± Error Standard (ES) de 55,10 ± 4,76 de individuos y una correlación con la población total de 99,60%, R2 =0,99 y p &lt; 0,0001; comparado con 3,44 ± 0,57 individuos y una correlación de 66,32%; R2=0,44 y p &lt; 0,0001 para la superficie del haz. El orden de eficacia de control para 3 días después de la aplicación de los tratamientos fue tiametoxam + lambdacihalotrina (0,00%), spinetoram, (0,00%), malation (20,35%), tiametoxam (38,62%), dimetoato (86,94%) e imidacloprid (87,33%); para 7 días fue tiametoxam + lambdacihalotrina (0,00%), spinetoram (21,46%), malation (38,77), tiametoxam (50,84%), dimetoato (86,14%) e imidacloprid (90,37%). Los datos de muestreo, a partir de 16 días, presentaron una gran pérdida de unidades experimentales, lo que imposibilitó el análisis de los resultados, después de ese tiempo.</p><p> </p><p><strong>Effect of Corythucha gossypii on Castor Oil Plant Leaves: Sampling Criteria and Control by Insecticides</strong></p><p>The lace bug, also called the “cotton or bean lace bug”, Corythucha gossypii (Fabricius) (Hemiptera: Tingidae) is a common pest from cotton. However it has been reported in another twenty four plant hosts including castor bean (Ricinus communis L.). This work aimed to establish if this insect pest can reduce the life-period of leaves, to assess which is the leaf surface that best represents the total pest population for sampling and to test the efficacy of six insecticides for C. gossypii control in a castor bean crop. The life-period of leaves was negatively affected by the presence of the insect, the larger the number of C. gossypii, the shorter their leaf life. The lower surface best represented the entire population of lace bug with a mean ± standard error of 55.10 ± 4.76, with a 99.60% of correlation, a R2=0.99 and a p &lt; 0.0001; compared to 3.44 ± 0.57, with a 66.32% of correlation, a R2=0.44 and a p &lt; 0.0001 for the upper surface. Efficacy of control after three days of insecticide application was: thiamethoxam + lambdacyhalothrin (0.00%), spinetoram, (0.00%), malathion (20.35%), thiamethoxam (38.62%), dimethoate (86.94%) and imidacloprid (87.33%). After seven days of insecticide application the efficacy was thiamethoxam + lambdacyhalothrin (0.00%), spinetoram (21.46%), malathion (38.77), thiamethoxam (50.84%), dimethoate (86.14%) and imidacloprid (90.37%). Results obtained after 16 days lacked many sampling unit leaves, which made their analysis meaningless, after that period of time. </p>

In this paper, we present a distributed collaborative system assisting physicians in diagnosis when processing medical images. This is a Web-based solution since the different participants and resources are on various sites. It is collaborative because these participants (physicians, radiologists, knowledgebasesdesigners, program developers for medical image processing, etc.) can work collaboratively to enhance the quality of programs and then the quality of the diagnosis results. It is intelligent since it is a knowledge-based system including, but not only, a knowledge base, an inference engine said supervision engine and ontologies. The current work deals with the osteoporosis detection in bone radiographies. We rely on program supervision techniques that aim to automatically plan and control complex software usage. Our main contribution is to allow physicians, who are not experts in computing, to benefit from technological advances made by experts in image processing, and then to efficiently use various osteoporosis detection programs in a distributed environment.

Aim: Information on the influence of water availability during different seasons of rainfed or irrigated agriculture as it relates to insect pest population build-up in crops could assist in the development of integrated pest management. A study was therefore conducted to investigate effects of spacing, pest infestation and control on cucumber under rainfed and irrigated conditions. Place and Duration of Study: At the Teaching and Research Farm, Ekiti State University, Ado Ekiti, Nigeria during the 2016/2017 rainy and dry seasons. Methodology: The experiment was laid out using randomized complete block design (RCBD) in a split-plot arrangement in five replications, with spacing (60 x 60 cm, 60 x 90 cm and 60 x 120 cm) as the main plot treatments and the sub-plot treatments were different pest control strategies. The pest control strategies include synthetic insecticide (Lambda-cyhalothrin), botanical insecticide (Anogeissus leiocarpus) and control. Growth parameters and yield attributes were recorded. Insect pest occurrence, their build-up and percentage infestation on cucumber and the efficacy of the management strategies were monitored. Results: The results showed that yield was enhanced in irrigated system with the widest spacing of 60 x 120 cm botanical treatment interaction. Bemisia tabaci was the most prominent insect pest attacking cucumber under irrigated system. Conclusion: Other cultural control practices such as the use of trap crops with little or no financial implication should also be added to botanical pesticides as an integrated pest management tactic for effective management and control of the pest.
