Resumo. Com o intuito de testar a tecnologia de película de partículas minerais com produtos existentes no mercado brasileiro, este trabalho avaliou a ação de caulim e calcário líquido na oviposição de Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Foram realizados ensaios de laboratório com maçãs e mangas, onde os frutos foram submetidos a pulverizações com caulim e calcário líquido (20% produto + água + espalhante adesivo Break Thru®) e controles (água e água + o espalhante adesivo) e expostos, individualmente, em gaiolas contendo dez fêmeas de C. capitata, alimento e água. Após 24 horas, os frutos foram removidos das gaiolas e decorridas mais 24 horas, removia-se a película mineral e contava-se as o número de puncturas nestes. A média de puncturas registradas nos frutos dos controles, em maçãs e em mangas foi maior do que a dos frutos tratados. Caulim e calcário líquido não diferiram entre si nos dois experimentos.  Em condições de laboratório, os produtos testados impediram a oviposição das moscas, reduzindo a infestação nos frutos.Minerals particles films on mediterranean fruit fly oviposition in laboratory assaysAbstract. In order to test the technology of mineral particle film with products existing in the Brazilian market, this work evaluate the action of kaolin and limestone liquid on Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) oviposition. Laboratory tests were carried out with apples and mangoes, where the fruits were sprayed with kaolin and liquid limestone (20% product + water + Break Thru ® adhesive) and controls (water and water + adhesive spreader) and individually exposed in cages containing ten C. capitata females, food and water. After 24 hours, the fruits were removed from the cages and after another 24 hours, the mineral film was removed and the number of punctures counted therein. The mean number of punctures recorded in the fruits of controls, apples and mangoes was higher than that of treated fruits. Kaolin and liquid limestone did not differ between the two experiments. Under laboratory conditions, the tested products prevented the oviposition of the flies, reducing infestation in the fruits.

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.
