“…TM is an effective lure for surveying and monitoring activities for male Mediterranean fruit flies (Grout et al 2011) and members of the Ceratitis FAR complex (Virgilio et al 2008) including Ceratitis rosa . Ceratitis cosyra males are not attracted to TM but to TA (White and Elson-Harris 1994).…”

Two standard parapheromones, trimedlure (routinely used for monitoring Ceratitis rosa and Ceratitis capitata) and terpinyl acetate (routinely used for monitoring Ceratitis cosyra) were compared with enriched ginger root oil (EGO) lure for detecting and monitoring the presence and relative population abundance of these particular pest species. Standard yellow fruit fly traps were used for the comparison, which was conducted at 10 sites along an altitudinal transect ranging from 540 to 1650 masl on the Uluguru mountains, in Morogoro Region (Central Tanzania). A gradual change of relative occurrence of the two Ceratitis rosa morphotypes was clear from the EGO lure trapping. The morphotype R1 was predominant at lower altitudes while morphotype R2 was predominant at higher altitudes. Further experiments are needed to confirm the consistency of the observed pattern across regions, seasons and years as well as possible differences in the developmental physiology of both morphotypes. The mango fruit fly, Ceratitis cosyra, showed a distinct predominance at altitudes below 800 masl as shown in both the EGO lure and the terpinyl acetate trapping. The catches of all three target species were higher in traps with the EGO lure compared to the conventional lures trimedlure and terpinyl acetate. It is argued that for these species EGO lure can act as a suitable and more effective alternative for trimedlure and terpinyl acetate parapheromones. In addition, EGO lure has the added advantage that it combines the taxon spectrum for the two latter substances, thus requiring the use of only a single attractant.

“…food attractant) for encouraging movement in the semi-field environment. When trapping for C. capitata, Biolure w has been shown to have the greatest recapture rate of both sexes compared with sex pheromone-based lures [41]. This is because Tephritids in general have limited access to protein in their natural diet despite this being essential for reaching sexual maturity, e.g.…”

“…Flies from each treatment group were marked with one of the three fluorescent powders ( pink, blue and yellow) that were randomly assigned prior to each release. A three-component protein pheromone attractant (ammonium acetate, trimethylamine hydrochloride and 1,4-diaminobutane; Biolurew, Chempac, Paarl, South Africa) that attracts both sexes of C. capitata [41] was opened for 10 min at one end of a 15 Â 3 m rectangular greenhouse before being sealed into an airtight container to create a pheromone gradient. Flies were then released from ground level at the opposite end of the empty greenhouse and allowed to move without human interference.…”

Enhanced dispersal ability may lead to accelerated range expansion and increased rates of population establishment, thereby affecting population genetic structure and evolutionary potential. Morphological, behavioural and physiological traits that characterize dispersive individuals from residents are poorly understood for many invertebrate systems, especially in nonpolymorphic pterygote species. Here we examined phenotypic differences between dispersal-prone and philopatric individuals from repeated markrelease-recapture (MRR) experiments using an invasive agricultural pest, Ceratitis capitata. Comprehensive morphometric assessment and subsequent minimal adequate modelling using an information theoretic approach identified thorax mass : body mass ratio as a key predictor of disperser flies under semi-natural conditions. Performance differences in flight ability were then examined under controlled laboratory conditions to assess whether greater thorax mass : body mass ratio was associated with enhanced flight ability. The larger thorax : body mass ratio was associated with measurable differences in mean flight duration, most predominantly in males, and also by their willingness to disperse, scored as the number and duration of voluntary flights. No other measures of whole-animal flight performance (e.g. mean and peak vertical force, total or maximum flight duration) differed. Variation in voluntary behaviour may result in significant alterations of movement behaviour and realized dispersal in nature. This phenomenon may help explain intraspecific variation in the dispersal ability of insects.

“…However, the best trap density for monitoring these insects in citrus is unknown and may depend on the fruit fly population. Although there are some indications on control thresholds for fruit flies , little research has been done on the relationship between insect trap captures and the damage caused (AGUNLOYE, 1987;UCHÔA-FERNANDES et al, 2003;GROUT et al, 2011). The objectives of this research were to evaluate the effect of pH of the attractant suspension and also estimate the control threshold for C. capitata at four trap densities, based on captures and fruit damage in Hamlin variety (sweet orange).…”

McPhail traps with hydrolyzed proteins, or similar products, have been the most used, despite being considered expensive, difficult to use and inefficient (ALUJA, 1994), because they are able to capture different tephritid species.…”

-This study evaluated the effect of initial pH values of 4.5, 6.5 and 8.5 of the attractant (protein bait) Milhocina® and borax (sodium borate) in the field, on the capture of fruit flies in McPhail traps, using 1, 2, 4 and 8 traps per hectare, in order to estimate control thresholds in a Hamlin orange grove in the central region of the state of São Paulo. The most abundant fruit fly species was Ceratitis capitata, comprising almost 99% of the fruit flies captured, of which 80% were females. The largest captures of C. capitata were found in traps baited with Milhocina® and borax at pH 8.5. Captures per trap for the four densities were similar, indicating that the population can be estimated with one trap per hectare in areas with high populations. It was found positive relationships between captures of C. capitata and the number of Hamlin oranges damaged, 2 and 3 weeks after capture. It was obtained equations that correlate captures and damage levels which can be used to estimate control thresholds. The average loss caused in Hamlin orange fruits by C. capitata was 2.5 tons per hectare or 7.5% of production. Index terms: true fruit flies, protein bait, damage, IPM, Citros. POTENCIAL HIDROGENIÔNICO (pH) DO ATRATIVO, DENSIDADE DE ARMADILHAS E NÍVEL DE CONTROLE PARA Ceratitis capitata (DIPTERA: TEPHRITIDAE) EM LARANJA HAMLIN NA REGIÃO CENTRAL DE SÃO PAULO, BRASILRESUMO -Esta pesquisa teve como objetivos: avaliar o efeito do pH inicial, 4.5; 6.5 e 8.5, do atrativo proteico Milhocina® e bórax (tetraborato de sódio) na captura de moscas-das-frutas em armadilhas McPhail; estudar densidades de armadilhas, 1; 2; 4 e 8 por hectare, para estimar níveis de controle em laranja cv. Hamlin, na região central de São Paulo. A espécie predominante, com 99% das moscas-das-frutas capturadas, foi Ceratitis capitata, sendo 80% de fêmeas. As maiores capturas de C. capitata ocorreram nas armadilhas com Milhocina® e bórax em pH 8.5. As capturas, nas 4 densidades, foram semelhantes, indicando que a população pode ser estimada com uma armadilha por hectare em áreas de altas populações. Houve relações positivas entre capturas de C. capitata e o número de frutos danificados, 2 e 3 semanas após a captura. Assim, foram obtidas equações que relacionam a captura e o dano, possibilitando estimar níveis de controle desse inseto. As perdas médias causadas por C. capitata em laranja cv. Hamlin chegaram a 2,5 toneladas de frutos por hectare ou 7,5% da produção. Termos para indexação: moscas-das-frutas, dano, atrativo proteico, MIP, Cítros.
