Abstract In this article, the authors report on the experiences of six years of foraging, describing how the fruit wastes generated in the Pannonhalmi Pálinkárium are utilized for foraging Hungarian grey cattle. The goal is not the control or improvement of the cattle’s growth indices but the problem-free, continuous and eco-friendly disposal of the fruit waste. They have found that the fruit waste or pomace is virtually nothing else than protein-enriched sugar-free fruit, and that during the utilization of this they have to maximally adapt to the cattle’s life-cycle, biological nature and environmental factors, and they will repay you by eating the pomace. They conclude that the grey cattle are a skin-and-hairs-covered bioreactor, which provides an economical service for the distillery through the utilization of the fruit waste. Nowadays, 150,000-200,000 tons of fruit waste is produced every year, and only a few percent of this is utilized in ruminant forage. By writing this article, the authors would like to expand our very scarce knowledge on this topic.

Abstract The arrival of spotted wing Drosophila, Drosophila suzukii (Matsumura), to the United States has caused many berry and cherry growers to replace IPM programs with calendar-based broad-spectrum insecticide programs. Alternative management tactics are urgently needed to mitigate the current dependency on chemical control. Postharvest burial is a cultural crop sanitation strategy that has the potential to reduce D. suzukii reproductive habitat and eliminate infested fruit wastes. This study revealed that D. suzukii rarely pupate on the soil’s surface or below 1 cm, but are capable of unburying themselves from depths up to 48 cm. Although zero emergence was not obtained in the field, adult emergence decreased exponentially with deeper burial depths. A burial depth of 24 cm reduced D. suzukii emergence by 97%, although soil texture may influence this optimal burial depth. Soils that had a higher concentration of sand had a negative impact on D. suzukii survival at shallower burial depths. The mechanism behind the reduction in adult emergence from differing burial depths remains unclear as the lipid concentration between emerging D. suzukii was the same regardless of burial depth.

Tigriopus fulvus (Fischer, 1860) is a benthic harpacticoid copepod of the Mediterranean supralittoral zone. The transitional characteristics of this environment forced this species to develop high resistance to changes of environmental parameters. Nevertheless, Tigriopus fulvus life-cycle is influenced from the splashpools physical-chemical parameters. In this paper, we present the results of a supralittoral monitoring performed in 2014, confirming the influence of some of these environmental parameters on population buildups. Because of recent worldwide climate change effects, a threat might have been posed on this particularly exposed organism, whose population density decreased of a sixfold value in the last 30 years. During the three pools (A, B, C) monitoring, the maximum copepod density recorded was 1456 Ind/l (September 2014, Pool C), alongside first records of extinction event for Tigriopus fulvus.

Occasional invader species include a variety of arthropods such as amphipods, centipedes, insects, millipedes, pill and sowbugs, scorpions, and spiders as well as nonarthropod mollusks and worms. These species present unique challenges for development of effective IPM programs. Most occasional invaders are susceptible to desiccation and temperature extremes or are in a wandering or migration phase of their life cycle. Environmental factors such as weather and the condition of homes and home landscapes affect occasional invader infestations. Successful IPM programs have been developed for the garden millipede, Oxidus gracilis Koch, and the smokybrown cockroach, Periplaneta fuliginosa (Serville). Both programs rely primarily on habitat modification based on pest biology. Results indicate that these occasional invaders can be managed without resorting to broadcast application of nonspecific insecticides.

AbstractEvylaeus nigripes (Lep.) is a large, polylectic social halictine bee, common in the Mediterranean region. Haplometrotic and pleometrotic nests are established late in spring and clusters of from 6 to 15 cells are constructed and surrounded by a cavity. A summer brood of small females and a few males emerges from these cells in July. The summer females behave as workers; they remain in their mother’s nest, assist in the construction of a deeper and larger cell cluster, forage for pollen and nectar, but do not guard the nest. They show some ovarian inhibition in a matrifilial society but become egglayers in queenless nests or when establishing their own burrows. They are much shorter-lived than their mothers, require no diapause, and are unattractive to the summer males. The social level of E. nigripes is comparatively high; summer males are less than 5% of the total brood. Queen and workers are relatively distinct morphs, although caste determination can be influenced by environmental factors. Sphecodes alternatus Smith is its specific parasitoid whereas several bombyliids, mutillids, and conopids attack E. nigripes as part of a much wider range of hosts.

Abstract. Isotopic signatures of ostracod shells became common proxies for the reconstruction of paleo-environmental conditions. Their isotopic composition is the result of the composition of their host water and the phenology and ecology of the target species. The sum of spatial and temporal variations from environmental factors in the species habitat defines the maximum isotopic variation of a population during the time of their shell formation. Here we present isotopic signatures (δ18O, δ13C) of living Cytheridella ilosvayi (Ostracoda) and chemical and isotopic compositions of 14 simultaneously sampled freshwater habitats in South Florida and instrumental data of the region. The chemical and isotopic compositions of the selected sites characterize the different habitats and show the influence of the source water, biological activity and the duration of exposure to the surface. Isotopic signatures of C. ilosvayi shells correlate well with the isotopic composition of their host waters. Within-sample variability of repeated isotopic measurements of ostracod shells reflect habitat dependent ranges and indicate temperature and the δ18O composition of precipitation (δ18Oprec) as regional environmental factors responsible for the population variation. Instrumental data of water temperature and δ18Oprec were used to calculate the monthly variation of a theoretical calcite in rivers of Florida showing distinct seasonal variations in values and ranges. Different configurations of the theoretical calcite were compared to the within-sample variability to identify possible calcification periods of C. ilosvayi. For a plausible calcification period the ostracod isotopic range has to correlate with mean values of the theoretical calcite with a slight positive offset (vital effect) and the extension of the theoretical calcite range. The tested model suggests a seasonal calcification period of C. ilosvayi in early spring. The surprising seasonality of a tropical ostracod life cycle is probably coupled to the hydrologic cycle of Florida. The results of this study contribute to the application of ostracod isotopes in modern calibration studies and their potential use in paleontology.

Particularly in the fruit juice industry, the remaining peels and pulp parts are not available for human consumption after the juices are used. It is possible to evaluate these wastes by adding them to poultry feeds. A number of studies have been conducted by researchers on the nutritional value of many fruit wastes and on the performance of poultry. Natural antioxidant content has been reported to have a positive effect on growth, microbial and immunological parameters when high fruit peels are used as feed additive in poultry feeding.

The effects of environmental factors on components of the life cycle of Puccinia menthae on Mentha × piperita cv. Tod’s Mitcham were examined. Urediniospore germination required at least 6 h leaf wetness and lasted 4-6 h at temperatures of 5-25ºC. Appressoria, substomatal vesicles, and haustoria were produced 6, 6, and 24 h after inoculation, respectively, at 20ºC. The latent period of infection ranged from 50 days at 5ºC to 10 days at 22ºC. Sporulation occurred over a wide range of temperatures (5-27ºC), the optimum being 15-20ºC. The minimum, optimum, and maximum temperatures for infection were <5, 20, and 27ºC, respectively. Teliospore formation required a minimum of 9 days of cold treatment (4ºC) and the ratio of teliospores to urediniospores produced was inversely proportional to the duration and intensity of light received.
