AbstractSeasonal emergence, abundance, biting and oviposition activity of Mansonia perturbans (Walker) were monitored in southwestern Ontario during 1977 and 1978. Adults emerged from 13 June until 24 August with the greatest emergence occurring in mid-June and mid-July. In both 1977 and 1978, adults were collected by dry ice-baited CDC light traps from 7 June until at least 7 September, with a peak of abundance in late June, followed by a smaller second peak in early August. Biting activity occurred from the second week of June until the first week in September with a maximum during the last week of June. Oviposition occurred from 30 June until 24 August with a maximum in early July.

The Florida Keys Mosquito Control District has used dry ice-baited light traps to monitor mosquito populations on Vaca Key since 1998. The first site sampled was monitored continuously for almost 20 years until all vegetation was removed. This paper describes a dataset compiled over almost 20 years of continuous trapping along Manor Lane on Vaca Key, Florida.

AbstractMean weekly catch of adult Psila rosae (F.) on sticky, yellow-painted cardboard traps from 93 commercial carrot fields provided seasonal records of their activity during 1980–1983 in the lower Fraser Valley, British Columbia. When monitoring extended from April through November in 1982 and 1983, 3 distinct periods of adult activity were observed that probably reflect the occurrence of 3 adult generations per year. Trap catch first peaked in mid- to late-May, followed by a second peak in late-July to early-August, and a third peak in mid-October. Of the temperature summations calculated, those commencing 1 February provided the most accurate degree-day (DD) indices for predicting seasonal activity of overwintering and 1st-generation adults. Four-year means for cumulative DD above 3 °C (air temperature) after 1 February for first, 10%, maximum, and 90% trap catch of the overwintering generation were 326, 435, 557, and 838 DD, respectively.

Arboviruses are arthropod-dependent viruses to complete their zoonotic cycle. Among the transmitting arthropods, culicids stand out, which participate in the cycle of several arboviruses that can affect humans. The present study aimed to identify species of culicidae and to point out the risk of circulation, emergency, or reemergence of pathogenic arboviruses to humans in the region of the Jequitibá headquarters of the Parque Estadual dos Três Picos (PETP), in Cachoeiras de Macacu, state of Rio de Janeiro, Brazil. Sampling was carried out at five Sample Points (SP) demarcated on trails from the headquarters, with CDC light traps, HP model with dry ice attached to the side, for 48 hours of activity each month. Additionally, active catches were made with a castro catcher in the period of one hour per day in the field, from six to eleven o’clock in the morning, in each PM. After the captures, thematic map was assembled using the ArcGIS 10 software and performing a multidimensional scaling (MDS). A total of 1151 specimens were captured and the presence of culicids already incriminated as vectors of arboviruses circulating in the region was observed: Aedes fluviatilis Lutz, 1904 (71 specimens); Aedes scapularis Rondani, 1848 (55 specimens); Haemagogus leococelaenus Dyar and Shannon, 1924 (29 specimens). In addition to the subgenus Culex (culex) spp. (163 specimens). In this sense, we highlight the importance of strengthening the actions of continuous entomological surveillance of the emergence and re-emergence of new arboviruses in ecotourism visitation parks.

The diversity and seasonality for sandflies were studied in 2019 at a focus of zoonotic cutaneous leishmaniasis in Zagora province, southern Morocco. Standardized sampling with CDC light traps was used. A total of 4504 sandflies (4024 Phlebotomus and 480 Sergentomyia) was collected during the study period. Seven species belonging to genus Phlebotomus and six species of genus Sergentomyia were identified. The most abundant species were Ph. papatasi (33.6%) and Ph. longicuspis (25.7%), highlighting the risk for local disease transmission foci. The seasonal activity of sandflies extended from April to November, showing two peaks, one in June-July and one, less important, in late-September-October. Abundance was highest during the months May, June, and July and lowest in August, September, and October. Results of this study provide important baseline data for planning control interventions.

Ixodid ticks are the most important arthropod hematophagies in veterinary medicine. The spread of ticks and tick borne diseases is linked to human activities, including habitat change, deforestation, economic globalization, international animal movements, urbanization and climate change. The research was conducted from March 2018 to March 2019 in Khmelnytsky region. In total were collected 2086 D. reticulatus ticks and 658 I. ricinus ticks. During the studies, two peaks of seasonal activity of both species of ticks were observed according to the average number of specimens in the three study areas. Spring activity began in March, and the peak was observed in April. Males were found to be more active in March and the first half of April, while females dominated males from late May to late June. The second peak of activity in the study area began in mid-September. Since the beginning of September, the activity of ticks has increased almost eight times compared to August. The peak of autumn activity was observed in late October and early November. Active females dominated males from early October to late autumn. From mid-June to mid-September, single specimens of ticks were detected. During the winter, no ticks were found in the experimental plots. On average, in all experimental areas of Khmelnytsky region, ticks were active at a temperature of 10.8 to 27.8 °C (average temperature – 21.6 ± 6.57 °C) and humidity – 39.90–78.20 % (average humidity – 61.79 %). Statistical analysis performed for all study areas showed that air temperature significantly affected the activity of both species of ticks. However, correlations between the number of ticks collected and humidity throughout the study area and in different areas were not observed separately. The largest number of ticks was collected during the period when daylight lasted approximately 12–14 hours; in turn, the lowest number of ticks was detected on days with more than 15 hours of daylight. Statistical analysis confirmed the correlation between the length of daylight and the activity of ticks of both species.
