In the cotton crop (Gossypium hirsutum L.), there is a complexity of pests that appear systematically, thus significantly reducing yield; and their population fluctuation strongly influenced by meteorological conditions result in greater or lesser density these insects. Thus, this work aimed to evaluate insect with sucking feeding behavior an area without irrigation plant under second-harvest c...

Twenty-eight greenhouse screening materials, with predetermined airflow resistance values, were evaluated for exclusion of the silverleaf whitefly Bemisia argentifolii Perring & Bellows and thrips from a mixed-species population. Screens differed in exclusion efficacy, expressed as a percentage of the fiberglass window screen control and at an approach velocity of 92 m/min, from -35 to 94% for ...

UNLABELLED Tomato yellow leaf curl virus (TYLCV) is a begomovirus transmitted exclusively by the whitefly Bemisia tabaci in a persistent, circulative manner. Replication of TYLCV in its vector remains controversial, and thus far, the virus has been considered to be nonpropagative. Following 8 h of acquisition on TYLCV-infected tomato plants or purified virions and then transfer to non-TYLCV-hos...

This study mathematically correlates incidence of cotton leaf curl virus (CLCuV), environmental factors (i.e., rainfall, humidity and temperature), and silverleaf whitefly population in agricultural system of Pakistan. It has been concluded that the disease is directly linked with rainfall and humidity. The third most influential factor in defining CLCuV incidence is the vector population, whic...

A study was conducted to evaluate the use of reflective mulch and host plant resistance for the management of the sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), in watermelon [Citrullus lanatus var. lanatus (Thunberg) Matsum & Nakai]. Whitefly abundance data were collected under both greenhouse (caged and uncaged) and field conditions. Consistently, a reflective mulc...

During 1996, 1997, and 1999, studies were conducted in cotton, sugar beets, alfalfa, yardlong bean, and peanut fields to compare insect catches in CC traps equipped with different trap base colors. The studies were conducted in southwestern United States, China, and India. The nine colors, white, rum, red, yellow, lime green, spring green, woodland green (dark green), true blue, and black, vari...

Gene array technology was applied to tomato as a model system to examine plant physiological response to silverleaf whitefly (SLW), Bemisia argentifolii (a.k.a. Bemisia tabaci biotype B) feeding. Our objective was to study gene expression in tomato plants subjected to a moderate infestation of whitefly. Plants were destructively harvested 25 days after infestation and samples of old and young l...

Abstract Integrated pest management (IPM) seeks to minimize the environmental impact of pesticide application, and reduce risks human animal health. IPM is based on two important aspects – prevention monitoring diseases insect pests which today are being assisted by sensing artificial-intelligence (AI) techniques. In this paper, we surveyed detection diagnosis, with AI, pests, in cotton, have b...

A pathogen may cause infected plants to promote the performance of its transmitting vector, which accelerates the spread of the pathogen. This positive effect of a pathogen on its vector via their shared host plant is termed indirect mutualism. For example, terpene biosynthesis is suppressed in begomovirus-infected plants, leading to reduced plant resistance and enhanced performance of the whit...
