Such differential colonization might suggest some degree of resistance by certain Passiflora species or oviposition preference by B. showed intermediate levels of colonization. flavicarpa Degener, were mostly uncolonised. and two commercially cultivated species, P.
amethystina Mikan was the most preferred species for oviposition and colonization, whereas P. We examined the colonization of nine Passiflora species by a wild B type population under greenhouse conditions. E-mail: note is the first report of Bemisia tabaci ( Gennadius) biotype B colonizing passionvine in Brazil.
(author)Įnergy Technology Data Exchange (ETDEWEB) This note is the first report of Bemisia tabaci ( Gennadius) biotype B colonizing passionvine in Brazil. (author)įirst report and differential colonization of Passiflora species by the B biotype of Bemisia tabaci ( Gennadius) (Hemiptera: Aleyrodidae) in Brazil From the tested insecticides, acetamaprid gave effective control of both nymph and adult population of B. whereas, endosulfan was found to be the least effective on both populations as adult and nymph of whitefly. Acetamiprid was the most effective against adult population of whitefly (0.3 to 1.3/leaf post 72 h spray, as compared to control with 6.9 to 8.2/leaf) followed by diafenthiuron and imidaclopirid. tabaci was 0.2/leaf after 24h spray as compared to 1.9/leaf in control. Results showed that buprofezin was the most effective insecticide against nymph population of whitefly among the tested insecticides where nymphal population of B. Ashfaq, M.Ĭomparative efficacy of five commonly used insecticides viz., acetamiprid, buprofezin, diafenthiuron, imidacloprid and endosulfan against nymph and adult population of cotton whitefly, Bemisia tabaci ( Gennadius) (Homoptera: Aleyrodidae) under natural field conditions has been studied. International Nuclear Information System (INIS) tabaci and disease incidence of CMMV.Ĭomparative efficacy of some insecticides against cotton whitefly, bemisia tabaci ( gennadius) (homoptera: aleyrodidae) under natural field conditions The results showed that BPMC is effective in suppressing the adult population of B. five concentration levels: 0.75, 1.50,2.25, and 3.00 ml/l including control (untreated with 5 replications. Research was conducted in the field with randomized complete block design consisting of 5 treatments i.e. tabaci populations and disease incidence of CMMV on soybean plants. This study aims to determine the influence of applications BPMC (500 g a.i./l against B.
There was no significant difference in preference for flowering Chinese cabbage and sweet potato, sweet pota-to, cabbage and tomato or between cabbage and tomato.Įffectiveness of BPMC Application against Bemisia tabaci ( Gennadius Population and CMMV Disease Incidence on Soybeanĭirectory of Open Access Journals (Sweden)įull Text Available Control of whitefly ( Bemisia tabaci ( Gennadius is the starting point in suppressing the CMMV disease (cowpea mild mottle virus. Preference was extremely sig-nificant between poinsettia and the other four plants, and between flowering Chinese cabbage, cabbage and toma-to. The order of prefer-ence was poinsettia > flowering Chinese cabbage > sweet potato > cabbage > tomato. tabaci adults were attracted by the odors of the five plants. The preferences of Bemisia tabaci Gennadius for five host plants:poinsettia, tomato, cabbage,sweet potato and flowering Chinese cabbage, was tested using a Y-tube olfactometer and a desiccator in the labo-ratory.
