Imidacloprid and the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin are both used to control the whitefly Bemisia argentifolii Bellows & Perring. We tested whether the two control strategies acted additively, synergistically, or antagonistically when combined for whitefly control. We found antagonism in that B. bassiana inhibited the effectiveness of imidacloprid. When B. bassia...

Some geminiviruses are transmitted by the whitefly Bemisia tabaci in a circulative manner. These geminiviruses are assigned to the genus Begomovirus within the family Geminiviridae. The route followed by begomoviruses in their insect vector and the velocity of translocation of the various viruses seem to be intrinsic to the whitefly, not to the virus. Subsequent to ingestion during feeding on a...

Plant pathogen interaction plays a great role in plant immunity. The regulation of various components of plant pathogen interactions is quite complicated and is very important in establishing relationship among components of this system. Yellow Mosaic Disease is common among legumes such as Vigna mungo. Mungbean Yellow Mosaic India Virus (MYMIV) and whitefly (Bemisia tabaci) is a vector causing...

Whiteflies cause damages to many economically important agricultural crops because of their feeding habits and their begomovirus transmissions. The whitefly Bemisia tabaci is a genetically diverse group, which includes a large number of different biotypes (see Part I, Chapter 3). It is extremely prolific; a single female may lay approximately 400 eggs during her lifetime. Unfertilized eggs give...

Abstract Sucking pests are major threat to cotton field crop which cause unbearable losses the yield. Aim of current study was record seasonal dynamics sucking insect including whitefly, jassid, thrips and their natural arthropod predators i.e. green lacewings spiders in plots. The effects surrounding crops on pests’ density predatory efficiency were also recorded. For sampling survey insects, ...

Four insects species have emerged as important pests of alfalfa in the Western United States during the past decade. Cowpea aphid has long been a resident insect of the Western United States, but became a significant alfalfa pest during the past two years. The silverleaf whitefly has been a serious pest of alfalfa since 1991. Silverleaf whitefly reduces hay yield and contaminates alfalfa hay wi...

abstract in recent decades the use of environmentally friendly biological and non-chemical materials for the control of plant pests has found good position. due to this reason the effect of some plant extracts (kernel extract of azadirachta indica with 1:12.5, fruit extract of chinaberry, fruit extract of iranian lilac and leaf extract of chinaberry with 1:3 with water), cotton seed oil and nee...

Surveys were conducted during 2017 and 2018 in the citrus orchards of Punjab, India to record incidence different insect pests their natural enemies. During October-December, Entomopathogenic Fungus (EPF), Aschersonia aleyrodis was found infect nymphs pupae whitefly, Dialeurodes citri on lower leaf surface Kinnow from Hoshiarpur, Ludhiana, Mansa Fazilka districts.The fungus isolated infected mo...

Whitefly is a populous insect pest among tomato pests, causing significant crop loss through direct and indirect attacks. The current study aimed to assess the knowledge of farmers on populousness whiteflies compared other pests explore management options available in their farming context three tomato-growing regions, Arusha, Morogoro, Iringa, Tanzania. used questionnaire collect data with bac...

Whitefly (Bemisia tabaci) is a polyphagous insect that causes huge damage in several horticultural crops, including tomato, by sucking nutrients from the phloem and transmitting viruses. Whiteflies are particularly difficult to manage use of chemicals remains common practice, which development insecticidal resistance. Thus, there considerable interest introduction resistance whitefly classical ...
