ABSTRACT The use of toxic baits with spinosyns (spinosad and spinetoram), along with the parasitoid Diachasmimorpha longicaudata, is a sustainable alternative for the management of Ceratitis capitata. This study aimed to evaluate the lethal concentration (LC) and lethal time (LT) of spinosad and spinetoram, associated with the food lures sugarcane molasses at 7 %, Biofruit at 3 %, Ceratrap® at 1.5 %, Flyral® at 1.25 %, Isca Samaritá® and Samaritá Tradicional® at 3 %, on C. capitata, under laboratory conditions, as well as their effect, at the concentration of 96 mg L-1, on D. longicaudata. For the lethal time data, mortality was assessed at 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 36, 48, 60, 72, 84 and 96 h after the exposure to the toxic baits. The lowest lethal concentrations (LC50 and LC95), to spinetoram (0.5 mg L-1 and 3.7 mg L-1, respectively) and spinosad (0.8 mg L-1 and 7.8 mg L-1, respectively), corresponded to the association with Samaritá Tradicional® at 3 %. The lowest lethal time (TL50), in hours, for the spinosad insecticide, corresponded to the formulation containing Biofruit at 3 % (6.6), and, to spinetoram, Samaritá Tradicional® at 3 % (7.9). For D. longicaudata, the formulations that caused the lowest mortality corresponded to the association of Biofruit® at 3 % with spinosad (4.7 %) and Samaritá Tradicional® at 3 % with espinetoram (3.5 %). The toxic baits formulated with spinosad and espinetoram, associated with Isca Samaritá® at 3 %, caused a mortality rate of more than 60 % to the parasitoid D. longicaudata.

Rearing Methods

Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a gregarious koinobiont endoparasitoid of frugivorous dipterans. In recent years, T. giffardianus has been detected parasitizing Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in different Brazilian semiarid sites. Thus, T. giffardianus has potential to be used in the biological control of C. capitata in semi-arid conditions. However, one of the factors limiting the use of this parasitoid is the lack of detailed information on rearing methods and bioecological aspects. Therefore, the main objectives of this study were to demonstrate a rearing technique for T. giffardianus and to determine the increase in population under laboratory conditions. Specimens of T. giffardianus were obtained in the field through of the collection of fruits infested with C. capitata. The specimens obtained were used to adapt a rearing methodology for T. giffardianus under laboratory conditions. Information on demographic parameters for a T. giffardianus population was obtained using the same methodology. Based on the parameters evaluated, we found that the intrinsic rate of population increase of T. giffardianus was 0.34, the average time of one generation was 19.7 days, the population doubling time was 2.03 days and the finite rate of population increase (?) was 1.41. The demographic parameters obtained demonstrated that, with the rearing technique used, it is possible to maintain populations of T. giffardianus and enable them to multiply under laboratory conditions.

The healthy maintenance of insects reared under laboratory conditions requires strategies to retain the natural characteristics of their life-histories traits. Rearing strategies include artificial selection to laboratory conditions, hybridization with compatible strains, and supplying the colony with wild individuals. We compared behavioral as well as life-history aspects of two laboratory strains of Ceratitis capitata Wiedemann (Diptera, Tephritidae) that had either been reared for 15-20 years under laboratory conditions with or without introducing wild specimens (Lab-Pop and Hybrid-pop, respectively). The parameters evaluated were: performance and food ingestion of immatures, adult size and longevity, female oviposition preference and fecundity, egg viability, and mating choice. Analyses of these parameters were conducted under laboratory rearing conditions. The largest differences observed between the two strains were related to behavioral components: food ingestion rate at the larval stage and oviposition behavior. In general, Lab-Pop individuals were less selective and more adapted to the artificial diet than Hybrid-Pop individuals (diet consumption), but there were no significant differences between the two strains in terms of percentage of emergence, egg viability, adult size, fecundity, and mating choice. It is suggested that the use of hybrid strains is more appropriate than the use of strains without the incorporation of wild individuals, especially in studies that involve behavioral parameters, as hybrid strains behave very similarly to wild populations, according our previous studies.

Two Drosophila species, D. aldrichi and D. buzzatii, colonised Opuntia cactus in Australia approximately 60 years ago. Only here are they sympatric. In laboratory population cages, D. buzzatii eliminated D. aldrichi in only a few generations. Thus analyses were done to identify competitive and life-history differences that may affect interactions between these species and their coexistence in nature. The two species differed in their responses with respect to preadult viability, size and developmental time, under intra- and interspecific larval competition, on simulated cactus rots in the laboratory. Increased intra- and interspecific density had similar effects on the larger of the two species, D. buzzatii. However, D. aldrichi showed greater decline in size and viability and greater increase in developmental time as a response to increased larval numbers of D. buzzatii, as compared with increased intraspecific density. Age of first reproduction and lifetime fecundity also favoured D. buzzatii under laboratory conditions. That D. buzzatii varied relatively less in developmental time suggested that it is better adapted to the smaller cactus necroses of O. stricta, present in the southern part of the cactus distribution where D. aldrichi is found rarely. Conversely, higher viability under crowded conditions suggested that D. aldrichi may be better adapted to poor environments such as older rots.

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.

Abstract Background The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is the major insect pest of fruit production worldwide. Chemical control of this pest has induced the selection of resistant medflies populations and negative environmental impact. In addition, the use of pesticides has become an obstacle to the fresh agricultural products exported to many countries that restrict pesticides residues. The aim of this study was to propose alternatives based on the use of microbiological products for the control of C. capitata. Main body The pathogenicity of the Turkish isolate Beauveria bassiana BMAUM M6-4 was evaluated against immature stages and adult of C. capitata under laboratory conditions at a concentration of 107 conidia/ml via different routes of exposure. Conidial treatment was applied by spraying soil and filter paper against 3rd instar larvae and pupae. In contrast, the treatment was administered to adult males and females by contact and ingestion. The percentage of mortality was recorded on the 3rd, 7th, 12th and 15th day after inoculation. Obtained results showed that B. bassiana was very effective against the adult’s fly, where males were more susceptible than females in both treatments (contact and ingestion). This isolate was tested against 3rd instar larvae. It achieved an infection rate of 33.33 and 43.5% of the larvae treated on filter paper and in the soil, respectively. Application of conidial preparations to soil reduced insect emergence and CAN represent a promising strategy for fruit fly integrated management (57.33 and 56.66% emergence from the treatments in soil and filter paper). Conclusion Entomopathogenic fungi are promising as a biocontrol agent that can be used under different modes of ground application against larvae, prepupae and pupae, and/or as a bait spraying or contact against adults.
