“…Classical animal production will soon not be able to feed the growing world population. Using the nutritional potential of edible insects as a source of food and feed appears to be one of the ways (Otero et al, 2022;Baiano, 2020). Insects contain a high protein content, which varies from 13 to 77% depending on the species and developmental stage (de Castro et al, 2018).…”

Úkolem Evropského úřadu pro bezpečnost potravin je poskytovat orgánům EU nezávislá vědecká stanoviska, vědeckou a technickou podporu pro legislativní a politickou činnost v oblastech, které mají přímý nebo nepřímý vliv na bezpečnost potravin a krmiv. Tato činnost má přispívat ke zvyšování důvěry spotřebitelů, hladkému fungování vnitřního trhu a vysoké úrovni ochrany zdraví lidí, zdraví a pohody zvířat, zdraví rostlin a ochrany životního prostředí. Jedním ze tří strategických cílů strategie EFSA do roku 2027 je zajištění připravenosti na budoucí potřeby analýzy rizik.Pro dosažení tohoto cíle EFSA úzce spolupracuje s národními vědeckými organizacemi a jednotlivými experty.

Competition between mosquito species during the larval phase is a well-established mechanism structuring container mosquito communities, with invasive species often outperforming natives. We assessed the competitive outcome between 2 species that occur on the island of Puerto Rico, the historic invasive Aedes aegypti (L.) and the endemic Aedes mediovittatus (Coquillett) (Diptera: Culicidae). Trials were conducted under intra- and interspecific densities crossed with 2 amounts of 4 different leaf types serving as detrital resources for developing larvae; leaf types were representative of either urban or rural locations. Response variables included survival, male and female mass and development time, and a composite index of population growth (λʹ). We also measured tannin levels in detrital environments, a secondary metabolite that can negatively influence mosquito development and survival. The co-occurrence of Ae. aegypti and Ae. mediovittatus generally did not affect survival or population growth of Ae. mediovittatus, however the converse was not true. Specifically, Ae. aegypti suffered lower survival and lower population growth in the presence of Ae. mediovittatus compared to when it was alone. Tannin concentrations did not correspond to competitive outcomes, as the highest tannin levels occurred under the detrital conditions where mosquitoes had highest growth and survival, with no evidence of differences between urban or rural leaf types. This is the first study to quantify the competitive outcomes between these species, both of which are part of the dengue transmission cycle on the island, and our findings suggest that Ae. mediovittatus is capable of outcompeting Ae. aegypti under some resource environments.

Objective To investigate the presence and abundance of mosquito species in containers found in different types of cemeteries in Puerto Rico to assess their importance and make control recommendations. Methods We conducted surveys of containers with water in 16 cemeteries in southeastern Puerto Rico to detect the presence of larvae and pupae of Aedes aegypti and other mosquitoes; to identify the most common and productive containers and to study their variation in relation to the type of cemetery. Results The most common containers with water were flowerpots, followed in abundance by a variety of discarded containers and open tombs. We found a positive relationship between density of containers with water and rainfall. There was a rich community of mosquito species developing in containers of the inspected cemeteries: nine mosquito species belonging to four genera with Ae. aegypti and Ae. mediovittatus being the most frequent and abundant. We sampled 13 cement‐type cemeteries, 2 mixed and only 1 lawn cemetery, consequently, we could not draw any conclusion regarding container productivity and cemetery type. Conclusions Surveyed cemeteries were important sources of Ae. aegypti and other mosquitoes in flowerpots, discarded containers and open tombs. We recommend conducting further studies to establish how frequently inspections should occur; and mosquito control by emptying aquatic habitats and larviciding to reduce mosquito productivity and protect workers and visitors from mosquito bites and possible transmission of arboviruses.
