Abstract: The objective of this work was to evaluate the circadian feeding rhythm of the green-belly stink bug (Dichelops melacanthus) on corn (Zea mays), and to correlate it with meteorological parameters. The experiments were conducted in corn fields in the first (summer) and second (fall) crop seasons, in the municipality of Chapecó, in the state of Santa Catarina, Brazil. Plants in the V3 and V5 stages were covered with cages and infested with adults of D. melacanthus. After 24 hours of acclimation, the number of insects feeding on the plant stem was counted every three hours (at 6:00, 9:00, 12:00, 15:00, 18:00, 21:00, and 0:00 h). At night, a red led flashlight was used to visualize the insects without interfering with their behavior. Meteorological parameters were monitored and correlated to the number of insects feeding on the plants. In the first and second crop seasons, the number of insects feeding on the corn stem differed among evaluation times, with peak in the afternoon, in the evening, and at night. Few insects were found feeding at 6:00 and 9:00 h. There was a positive correlation between air temperature and feeding in both seasons. In milder temperature regions, the preferred feeding time of D. melacanthus on corn is during the afternoon, evening, and night hours, which should be taken into account for a precise management of this insect.

E-mail: [email protected]     1 RESUMO   O objetivo foi avaliar a aptidão climática em função da redução de produtividade para o cultivo em sucessão soja-milho safrinha em cenários futuros para o Estado Santa Catarina. Foram utilizados dados de precipitação, temperatura mínima e máxima do ar, em estações meteorológicas, localizadas em oito municípios do Estado, durante os anos de 1983 a 2014. Índices térmicos foram usados para definir a data de início das simulações em que o ciclo da soja pode iniciar e do milho safrinha terminar. Estes índices térmicos consideraram a probabilidade de ocorrência menor que 15% de temperatura mínima do ar ficar abaixo de 6 °C, sendo este indicativo de ocorrência de geada de radiação e de temperatura média diária do ar de 10 °C e 14 °C, como sendo as temperaturas basais inferior do milho e da soja, respectivamente. As simulações de redução na produtividade devido ao déficit hídrico para diferentes datas de semeadura da soja, e na sequência, para o milho safrinha, consideraram os cenários climáticos RCP4.5 e RCP8.5, à curto prazo e a médio prazo apresentados pelo Painel Intergovernamental sobre Mudança Climática. Os resultados indicam que apenas no oeste do Estado será possível adotar o cultivo em sucessão, sendo maior a janela de semeadura para as culturas, quanto maior o aumento da temperatura, da precipitação e do CO2 projetados pelos cenários.   Palavras-chave: déficit hídrico, mudanças climáticas, semeadura, produtividade.     MINUZZI, R. B.; FRETTA JOSÉ, M. Climatic aptitude for growing soybean-corn succession in future scenarios in Santa Catarina, Brazil     2 ABSTRACT   The objective was to evaluate climatic aptitude due to yield decrease for soybean-maize succession crop in future scenarios for the State of Santa Catarina. Precipitation, minimum and maximum air temperature data from meteorological stations, located in eight cities of the State, were used during the years 1983 to 2014. Thermal indexes were used to define the start date of simulations in which soybean cycle can start and maize crop ends. These thermal indices considered the probability of occurrence of less than 15% of minimum air temperature to be below 6 °C, as indicative of occurrence of frost and average daily air temperature of 10 °C and 14 °C, as being the lower basal temperatures for maize and soybean, respectively. Simulations of yield decrease due to water deficit for different dates of soybean sowing, and in the sequence, for maize crop, considered short-term projections and medium-term ones of the RCP4.5 and RCP8.5 scenarios of the Intergovernmental Panel on Climate Change. The results indicate that only in the West of the State will it be possible to adopt crop in succession, the larger the sowing window for crops, the greater the increase in temperature, precipitation and CO2 projected by the scenarios.   Keywords: water deficit, climatic change, sowing, yield.

Rapid Drop

An “explosive extratropical cyclone” is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, bomb cyclone. With gusts recorded of 116 km/h, atmospheric phenomenon – “cyclone bomb” (CB) hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. One of the cities most affected was Chapecó, west of the state of Santa Catarina. The satellite images show that the CB generated a low pressure (976 mbar) inside it, generating two atmospheric currents that moved at high speed. In a northwest-southeast direction, Bolivia and Paraguay, crossing the states of Parana and Santa Catarina, and this draft that hit the south of Brazil, which caused the destruction of the affected states.  Another moving to Argentina, southwest-northeast direction, due to high area of high pressure (1022 mbar). Both enhanced the phenomenon.

<p>In the Hidegvíz Valley experimental catchment in Hungary the meteorological data have been collected since the 1990s and used for various purposes including hydrological studies. Current research began in 2018–19, that aimed to reveal the connections between the hydrological and botanical characteristics in riparian forests and a wet meadow. Changes that occurred in both ecosystems in the groundwater levels, soil moisture and vegetation, showed that the local meteorological events influence these factors. Therefore we decided to analyse longer periods in which meteorological extremes<br>strongly influenced hydrological conditions and so status of ecosystems. Further measurements and their analysis were also required because more accuracy and detail were needed for future water balance modelling.</p><p>The measured data between 2017–2020 were chosen as a starting database. For the first analysis we selected three meteorological parameters, i. e. the precipitation, the air temperature, and the air humidity. These parameters were measured by automated instruments, except for the precipitation. We found that the automated tipping-bucket rain gauge needs validation by a manual measurement (Hellmann-type rain gauge), because the data that collected by the automated device will be invalid if the rain intensity is too high.</p><p>In 2017 and 2018, the annual precipitation was distributed evenly, but in the following two years we observed some extremes. In 2019 and<br>2020, the spring was especially dry, the lowest monthly sum was 1.2 mm in 2020 April. 2019 April was similar (19.5 mm), but after the drought<br>period intense rainfall events arrived in May, resulted a monthly total of 214.1 mm. Air temperature and air humidity has not been showed such extremes as the precipitation.</p><p>This study showed that detailed analysis of meteorological parameters is crucial for hydrological modelling data preparation because errors and extreme event can cause serious problems during modelling process and, also in case of evaluation of model results.</p><p>The research has been supported by the Ministry of Agriculture in Hungary.</p>

Seabather's eruption (SBE) is an intensely itchy, papule-erythematous dermatitis that occurs predominantly in regions of the body covered by bathing costumes, after exposure to marine water. The planulae larvae of Linuche unguiculata scyphomedusae (thimble jellyfish) are the etiologic agent of the dermatitis, which is frequent in waters of Caribbean, Gulf of Mexico and Florida. The authors report 38 cases of SBE in the State of Santa Catarina (Southern region of Brazil), with emphasis on their clinical and epidemiological aspects, such as profile of victim, topography of the papules and conditions predisposing to the accident.

This paper presents information from different sampling surveys carried out along the Santa Catarina coast in order to outline the biogeographical characteristics of the zooplankton in this region and identify species or groups of species with potential use as bioindicators. Based on a checklist of species of the zooplankton community in the state, it was observed that, in the warmer months of the year, the fauna is similar to that of the states of Paraná and São Paulo (e.g. Creseis virgula f. virgula, Penilia avirostris; Acartia lilljeborgi and Oithona oswaldocruzi), while in the colder months there are coastal representatives of the fauna of Rio Grande do Sul (e.g. Acartia tonsa). However, the zooplankton consists predominantly of warm water species for most of the year, which is typical of Tropical Shelf Waters. Various species of zooplankton can be used as hydrological indicators, enabling a distinction to be made between coastal waters which are influenced by continental inputs (e.g. Paracalanus quasimodo and Parvocalanus crassirostris), common in the north of the state, and processes of upwelling (e.g. Podon intermedius) and the influence of the Subtropical Shelf Front (e.g. Pleopis polyphemoides), coming from the south. The different environments investigated present a zooplankton abundance that depends on the influence of continental inputs and the possibility of their retaining and contribution for the coastal enrichment, which varies seasonally
