molecular phylogeny of tephritid fruit flies in the bactrocera tau complex using the mitochondrial coi sequences.we compared sequences of the mitochondrial cytochrome oxidase i gene of eight species of the bactrocera tau complex using bactrocera dorsalis, bactrocera pyrifoliae, ceratitis capitata, anopheles gambiae, and locusta migratoria as outgroups. a 639-bp variable region was sequenced. the sequence divergence between species in the b. tau complex ranged from 0.06 to 28%, and up to 29% between the complex and its tephritid outgroups, b. dorsalis and c. capitata. according to the phylogenetic relations ...200312669803
molecular and biochemical characterization of three bacterial symbionts of fruit fly, bactrocera tau (tephritidae: diptera).characterization of three bacterial symbionts (bc1, bc2 and bc3) of fruit fly bactrocera tau including morphological, biochemical and 16s rdna (rrs gene) analysis was done to determine their taxonomic position. morphological and biochemical characterization placed two bacteria (bc1, klebsiella oxytoca and bc2, pantoea agglomerans) into family enterobacteriaceae and the third one (bc3, staphylococcus sp.) into family staphylococcaceae. 16s rdna gene sequence comparison with the available ncbi dat ...200920118612
effect of larval density and host species on preimaginal development of bactrocera tau (diptera: tephritidae).the fruit fly, bactrocera tau (walker) (diptera: tephritidae), is an important pest of fruit and vegetable crops. in this study, host preference of b. tau females and the effects of host species and larval density on larval survival, pupal weight, adult emergence, and developmental duration were investigated on cucumber (cucumis sativus l.), sponge gourd (luffa cylindrical l. (roem)), bitter gourd [momordica charantia (cucurbitaceae) l.], guava [psidium guajava (myrtaceae) l.], and tangerine [ci ...201122299343

gamma irradiation as a phytosanitary treatment of bactrocera tau (diptera: tephritidae) in pumpkin fruits.the fruit fly bactrocera tau (walker) is an important quarantine pest that damages fruits and vegetables throughout asian regions. host commodities shipped from infested areas should undergo phytosanitary measures to reduce the risk of shipping viable flies. the dose-response tests with 1-d-old eggs and 3-, 5-, 7-, 8-d-old larvae were initiated to determine the most resistant stages in fruits, and the minimum dose for 99.9968% prevention of adult eclosion at 95% confidence level was validated in ...201526470107
the complete mitochondrial genome of the pumpkin fruit fly, bactrocera tau (diptera: tephritidae).the pumpkin fruit fly, bactrocera tau, is an important quarantine pest in many countries because of its mass destructiveness to a variety of vegetable and fruit plants. in this study, we report the complete mitochondrial genome (mitogenome) of b. tau. its complete mitogenome sequence is 15,687 bp in length, which contains a non-coding control region and all of the 37 genes of bilaterian animals (13 protein-coding genes, 22 trna genes and 2 rrna genes). a phylogenetic tree of the complete mitogen ...201626024140
competitive interactions between immature stages of bactrocera cucurbitae (coquillett) and bactrocera tau (walker) (diptera: tephritidae) under laboratory conditions.the melon fly, bactrocera cucurbitae (coquillett), and the pumpkin fly, bactrocera tau (walker), are economically important pests that attack mainly cucurbitacean fruits. the two fruit fly species have similar natural distributions, host ranges, and population growth capacities. this study was designed to assess the asymmetrical competitions through resource exploitation between the larvae of b. cucurbitae and b. tau at different density levels and temperatures, and on different hosts by compari ...201427193811
genetic structure and colonization history of the fruit fly bactrocera tau (diptera: tephritidae) in china and southeast asia.bactrocera tau (walker), a major invasive pest worldwide, was first described in fujian (china) in 1849 and has dispersed to tropical and subtropical asia and the south pacific region. few data are available on its colonization history and expansion processes. this pilot study attempted to reconstruct the colonization history and pathways of this pest in china and neighboring southeast asian countries based on mitochondrial dna. results of the study showed six genetic groups corresponding to geo ...201425026691
toxicity of phosphine fumigation against bactrocera tau at low temperature.bactrocera tau (walker) is one of the most harmful pests to fruits and vegetables. to counteract this pest, the development of phytosanitary treatment is required to comply with the pest regulation requirements of certain countries. this study investigated the toxicity of phosphine fumigation against b. tau under low temperature conditions. different growth stages (eggs and instars) of b. tau were exposed to 1.07 mg/liter phosphine for 1-10 d at 5 degrees c, and compared with unfumigated flies a ...201424772539
phenetic structure of two bactrocera tau cryptic species (diptera: tephritidae) infesting momordica cochinchinensis (cucurbitaceae) in thailand and laos.morphometric variation with respect to wing venation patterns was explored for 777 specimens of the bactrocera tau complex collected in thailand (nine provinces) and laos (one locality). cryptic species b. tau a and c were identified based on their wing shape similarity to published reference images. in thailand, the b. tau a species was identified in four provinces and the b. tau c species in seven provinces, and both species in one locality of laos. the objective of the study was to explain th ...201323332679
development of allele-specific single-nucleotide polymorphism-based polymerase chain reaction markers in cytochrome oxidase i for the differentiation of bactrocera papayae and bactrocera carambolae (diptera: tephritidae).differentiation of bactrocera papayae drew & hancock and bactrocera carambolae drew & hancock (diptera: tephritidae) based on morphological characters has often been problematical. we describe here a single-nucleotide polymorphism (snp)-based polymerase chain reaction (pcr) assay to differentiate between these two species. for detection of snps, fragments derived from each species were amplified using two primer pairs, coif/coir and uea7/uea10, sequenced, and aligned to obtain a contiguous 1,517 ...201021309218
the geometric approach to explore the bactrocera tau complex (diptera: tephritidae) in thailand.specimens of the genus bactrocera were collected from several host plants in northern and western thailand. they were morphologically recognized as bactrocera tau and were subdivided into eleven samples according to host plant, geographic origin and time of collection. twelve landmarks of the right wing were described in a total of 264 males and 276 females. an exploratory analysis using kernel density estimates was performed on the multivariate morphometric space. non-parametric classification ...201020817492
using two-sex life tables to determine fitness parameters of four bactrocera species (diptera: tephritidae) reared on a semi-artificial diet.fruit flies in the genus bactrocera are global, economically important pests of agricultural food crops. however, basic life history information about these pests, which is vital for designing more effective control methods, is currently lacking. artificial diets can be used as a suitable replacement for natural host plants for rearing fruit flies under laboratory conditions, and this study reports on the two-sex life-table parameters of four bactrocera species (bactrocera correcta, bactrocera d ...201728944746
