From 1998 to 2006, B. dorsalis was recovered from 29 different host fruit from the five Society Islands: Tahiti, Moorea, Raiatea, Tahaa, and Huahine. The goal of the present study was to evaluate whether the m … 2006;Cugala2011).Yield lossesdue to fruit fly infestation are reported to be more than 40% with-out control (Ekesi et al. Bactrocera dorsalis infested fruit had a significantly lower concentration than the control; this was more evident for 10 days after inoculation fruit . The official status of B.dorsalis for South Africa is: Present in some areas and under official control It can successfully be eradicated when detected early and response is quick in new areas (Manrakhan et.al, 2011) For that permanent surveillance, cooperative role … They may also mediate insecticide resistance within their hosts and thereby impact pest and vector control practices. Bactrocera dorsalis is a member of the Oriental fruit fly (B. dorsalis) species complex.This species complex forms a group within the subgenus Bactrocera and the name may therefore be cited as Bactrocera (Bactrocera) dorsalis.B. The Oriental fruit fly, Bactrocera dorsalis (Hendel), is among the most destructive fruit/vegetable-eating agricultural pests in the world, particularly in Asian countries such as China.

Eradication programs were conducted from 1997 to 2001, but failed. In severe cases, losses may reach up to 100% in some fruit crops. Vc concentration in orange juice differed among treatments (F 3, 11 = 32.053, P < 0.001). Applied Entomology and Zoology, Vol. Although initially thought to be a variant form of Bactrocera dorsalis, it was recognized as a distinct species (Drew et al., 2005). Chemical Composition and Behavioural Responses of Male and Female Bactrocera dorsalis to their Volatile Emissions Bactrocera dorsalis, (Tephritidae) presented a grave threat to a broad range of fruit and vegetables in the tropics, including Tanzania. The aim of this paper is to highlight the research findings on B. dorsalis in India, based on work carried out at IIHR, ... chemical (Jang & Light 1996). 44:279-302. The native distribution of Bactrocera carambolae overlaps extensively with that of B. dorsalis, in much of the southern part of its range, and it was introduced into Suriname about 1975 where it has become established. Status of Bactrocera dorsalis: Bactrocera dorsalis (Oriental Fruit Fly) is a quarantine pest of Asian origin capable of infesting various commercial fruit crops (400 recorded hosts).It was previously described as the Invader fruit fly (Bactrocera invadens).It is now found in … It is a common term used in the field of chemical ecology to encompass pheromones, allomones, kairomones, attractants and repellents. The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is one of the major insect pests which renders the fruit to become unfit for human consumption. Bactrocera kirki (Froggatt) in 1928, Bactrocera tryoni (Froggatt) in 1970, B. dorsalis in 1996, and Bactrocera xanthodes in 1998 (Leblanc and Putoa 2000). 3, p. 457. ABSTRACT: Bactrocera dorsalis (Hendel) has invaded Jiangxi, a subtropical area of China and poses a serious threat to its host crops, especially citrus fruits. From 1998 to 2006, B.dorsalis was recovered from 29 different host fruit from the five Society Islands: Tahiti, Moorea, Raiatea, Tahaa, and Huahine. Bactrocera dorsalis. Bactrocera carambolae, also known as the carambola fruit fly, is a fruit fly species in the family Tephritidae, and is native to Asia. In past years, this species has invaded South America via the trade of fruits from Indonesia. The Chemical ecology of the oriental fruit fly Bactrocera dorsalis and the potential for novel odor-based management tools. ... Chemical Control Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any specific chemical control recommendations. Mention of pro- It was previously described as the Invader fruit fly (Bactrocera invadens). PHYTOPHAGOUS insects use chemical cues emanating from plants to orient to their food hosts while plants ward off herbivory again through use of chemicals. Concerns Thus far, the ecological characteristics of B. dorsalis in this area remain unclear, which has restricted prevention and control efforts. Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), was discovered on Tahiti Island in July 1996. Bactrocera dorsalis (Hendel) ... of pre- and post-harvest management gave 100% control of B. dorsalis. This species was discovered by Drew and Hancock in 1994. Genetic variations among and within populations of the Oriental fruit fly, Bactrocera dorsalis (Diptera; Tephritidae), detected by PCR-RFLP of the mitochondrial control region. Insecti-cide applications to control fruit flies are done on a calendar basis and are widespread. Keywords: Bactrocera dorsalis, herbivory, fruit fly, India, mango, phenolics. Methyl eugenol is Plant Prot. When methyl eugenol (B. dorsalis male attractant) was mixed with basil oil, ... fore, it can be used as an alternative to chemical pest control (Olson and Bidlack 1997). 3.2. In that description, its native range was indicated as Sri Lanka. Chemical insecticides have been widely used for the prevention and control of this destructive pest. Abstract. (sammanfattning/summary) Alnarp : Sveriges lantbruksuniv., Acta Universitatis Agriculturae Sueciae, 1652-6880 ; 2017:62 ISBN 978-91-7760-014-5 eISBN 978-91-7760-015-2 Two tephritid species namely the oriental fruit fly Bactrocera dorsalis Hendel and the guava fruit fly Bactrocera correcta Bezzi are considered to be the key insect pests of fruit production in Thailand, causing yield loss and quality degradation. The oriental fruit fly, Bactrocera dorsalis (Hendel), is an important agricultural pest and has developed resistance to many insecticides. Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), was discovered on Tahiti Island in July 1996. It is now found in 65 countries and in most sub-Saharan countries. Bactrocera dorsalis is part of a larger species complex and PCR analysis indicated that, indeed, piggyBac exists throughout the complex having nucleotide sequence identities of 92% among all the elements sequenced, with individual identities of 96–99% to one another and the T. ni 3E1 piggyBac (Handler, unpublished data).
