Along the Montenegrin seacoast, all cultivated citrus species (mandarin, orange, lemon, grapefruit), fig, loquat and ziziphus were detected as host plants of the Ceratitis capitata Wiedem. Among those found, in economic sense, the most important host plant is mandarin Unsiu. Intensity of the attack were monitored on mandarin in 2003 and 2004 in localities Baosici, Lastva Grbaljska and Bar, and was determined as higher in 2003. The first symptoms of attack were detected, depending on locality, from middle of September until beginning of October, one to two months earlier then in 2004. The maximum number of larvae per fruit were detected in October and November (average from 13.44?0.16 to 22.82?0.13). Time of the first symptoms appearence on mandarin in September and October 2003 and in November 2004, indicate on crucial importance of alternative host plants (figs and loquat) for reproduction and increasing of C. capitata population, because later during a season its intensity of attack on mandarin, depend largely on their presence.

The Mediterranean fruit fly Ceratitis capitata Widem. has been an established pest on the Montenegrin seacoast for more than ten years, although with variable abundance in different years and localities. From an economic aspect, its most important host in Montenegro is the mandarin unshiu (Citrus unshiu Marc.), particularly its cultivar Owari. Dispersion of C. capitata in citrus orchards (prevailingly mandarin) was monitored on Baosici, Lastva Grbaljska and Bar localities during 2003 and 2004. The results of this study showed that, during both years, peripheral-row trees (primarily the first row) in citrus orchards were more exposed to attacks by C. capitata than middle and last rows. In 2003, the average number of larvae in mandarin fruits in first rows varied from 11.4?0.59 to 40.1?0.67, from 7.04?0.47 to 28.8?0.48 and from 2.9?0.07 to 17.3?0.54 on the localities of Baosici, Lastva Grbaljska and Bar, respectively. On the same localities, it ranged from 7.4?0.34 to 16.9?0.4, from 0.0 to 18.7?0.32 and from 0.0 to 9.93?0.56 in middle rows, and from 3.0?0.28 to 16.8?0.77, from 0.0 to 20.9?0.38 and from 0.0 to 13.1?0.39 in last rows. Data collected at Baosici, Lastva Grbaljska and Bar in 2003 also suggest that the average number of larvae per mandarin fruit in first rows was 1.78-2.08 times higher than in middle rows, and 1.25-1.77 times higher than in last rows. In 2004, the average number of larvae in mandarin fruits in first rows varied from 7.3?0.27 to 8.3?0.45, from 7.2?0.23 to 17.6?0.59 and from 3.8?0.1 to 8.8?0.25 on the localities of Baosici, Lastva Grbaljska and Bar, respectively. On these localities, it ranged from 1.7 ?0.17 to 3.3?0.19, from 1.1?0.12 to 3.5?0.8 and from 0.0 to 0.8?0.14 in middle rows, and from 1.7?0.17 to 3.6?0.32, from 0.0 to 4.0?0.26 and from 0.0 to 0.2?0.06 in last rows. Data collected in 2004 also showed that the average number of larvae in mandarin fruits in first rows on the same localities was 3.12-15.75 times higher than in middle rows, and 2.94 -6.3 times higher than in last rows.

Electroantennogram Recordings

The Mediterranean fruit fly, Ceratitis capitata Wied., is among the most serious pests in horticulture worldwide, due to its high reproductive potential, difficulty of control and broad polyphagy. The aim of this study was to measure—by means of the electroantennogram recordings— the antennal olfactory sensitivity of virgin, mated, male, female, lab-reared and wild C. capitata following stimulation with fruit and leaf headspace of some host-plants: clementine, orange, prickly pear, lemon and apple. The results show that: (a) lab-reared mated males are more sensitive to host-plant fruit and leaf headspace than females, while the opposite was true for wild insects; (b) antennae of wild virgin males were more sensitive than the mated ones, while no difference was observed among lab-reared medflies; (c) lab-reared virgin females were more sensitive than mated ones, while few differences were found within wild medflies; (d) in mated insects, lab-reared males were more sensitive to both host-plant fruits and leaves than the wild ones, while the opposite was found for females. Taken together, these results show that the olfactory sensitivity to host-plant odors differs between virgin and mated and lab-reared and wild flies.

Pupal Mortality

Abstract The Mediterranean fruit fly Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) is among the main pests of fruit crops worldwide. Biological control using entomopathogenic nematodes (EPNs) may be an alternative to suppress populations of this pest. Thus, the aim of this study was to evaluate the pathogenicity and virulence of six EPN isolates (Heterorhabditis bacteriophora HB, H. amazonensis IBCB-n24, Steinernema carpocapsae IBCB-n02, S. rarum PAM-25, S. glaseri IBCB-n47, and S. brazilense IBCB-n06) against C. capitata pupae. The compatibility of EPNs with different chemical insecticides that are registered for management of C. capitata was also assessed. Isolates of H. bacteriophora HB and S. brazilense IBCB-n06 at a concentration of 1,000 infective juveniles (IJ)/ml proved to be most pathogenic to C. capitata (70 and 80% mortality, respectively). In contrast, the isolates H. amazonensis IBCB-n24, Steinernema carpocapsae IBCB-n02, S. rarum PAM-25, S. glaseri IBCB-n47 provided pupal mortality of less than 60%. Bioassays to determine lethal concentrations indicated that concentrations of 600 IJ/ml (H. bacteriophora HB) and 1,000 IJ/ml (S. brazilense IBCB-n06) showed the highest virulence against C. capitata pupae. In contrast, the highest numbers of IJs emerged at concentrations of 1,200 and 200 IJ/ml. In compatibility bioassays, malathion, spinetoram, phosmet, acetamiprid, and novaluron were considered compatible with and harmless (Class 1) to H. bacteriophora HB and S. brazilense IBCB-n06, according to IOBC/WPRS. This information is important for implementing integrated management programs for C. capitata, using biological control with EPNs, whether alone or in combination with chemical insecticides.

Abstract Population fluctuations of the Mediterranean fruit fly (medfly), Ceratitis capitata, were investigated between 1999 and 2001 at several locations representing fruit production areas in the southern part of Syria (Damascus Ghota, Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab). Medfly adults were monitored weekly all year around using Jackson traps baited with trimedlure dispensers. Larvae were also sampled in Damascus Ghota by collecting fruits from ripe or ripening fruit trees and recording the number of larvae emerged from these fruits. In addition, suspected overwintering refuges were sampled at weekly intervals during the three coldest months of the year (December – February) and the number of collected larvae was recorded. The results of trap catches and fruit sampling studies showed a similar pattern of occurrence of medfly populations in the study areas, particularly in Damascus Ghota, during the three years of the study. In Damascus Ghota, flies were caught continuously from early June to late December with some variability between years. Two distinct periods of high fly activity were observed: the first one occurred in August and the second in November with a much higher amplitude. In general, seasonal fluctuations in the pattern of occurrence were influenced by differences in temperature and abundance of preferred host fruits. Traps on fig Ficus carica and oriental persimmon Diospyros kaki trees caught the highest numbers of flies, and fruits collected from these trees showed the highest level of infestation, reaching 100% for fig fruit late in the season. Sampling fruits (in Damascus Ghota) from trees during the three coldest months of the year showed that a small population of medfly larvae was able to survive winter conditions in prickly pear Opuntia vulgaris fruit left on the trees. In the other areas of the study (Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab), only a few flies were caught.
