Local potential competitor species are important determinants of the invasibility an environment even when widely recognized invasive concerned since it may compromise its establishment. Thus, outcome direct competition among khapra beetle, Trogoderma granarium, and cosmopolitan lesser grain borer, Rhyzopertha dominica rice weevil, Sitophilus oryzae, thus likelihood establishment T. granarium under their co-occurrence, was here explored in paddy wheat, at temperatures between 25 35°C through 200 days storage. Insect infestations were higher wheat rather than rice. unable to displace any competing two three-species experiments retaining lower adult population both local competitors lowest temperature level. prevailed rice, while S. oryzae wheat. Paradoxically, adults retained low growth but contributed more for total frass production loss, much that recorded R. dominica. Nonetheless, larvae exhibited high numbers 130 after introduction parental individuals. At levels (30 35°C) extremely 65 days, other rapidly declined. Interestingly, simultaneous presence beneficial granarium. Consequently, has ability outperform primary stored-product insects temperatures, remains long periods apparently unaffected by co-occurring species. Hence, is able outcompete major elevated 25°C this can maintain individuals periods, which produce outbursts prevailing conditions suitable development.

Urban trees facilitate the establishment of non-native forest insects

Cities, due to the presence of ports and airports high diversity trees in streets, parks, gardens, may play an important role for introduction invasive forest pests. We hypothesize that areas urban facilitate establishment non-native Based on scientific literature a pan-European database species feeding woody plants, we analysed where first detections occurred European countries. collected site data 137 Europe 508 country-specific records. also estimated percentage tree cover suitable habitat (green with trees) buffers around detection points. The large majority records (89% record 88% country) were found cities or suburban areas. Only 7% cases forests far from cities. probability occurrence decreased sharply distance city. be detected was higher sap feeders, gall makers, seed fruit feeders (>90%) than bark wood borers (81%). Detection sites highly diverse, including public street trees, university campus, arboreta, zoos, botanical gardens. average proportion less 10% detected. Further, more 72% 20% cover. Hotspots identified along coastal regions Mediterranean Atlantic, near industrial central Europe. conclude are main facilitators pests, should thus intensely surveyed. Moreover, as populated, involvement citizens is recommended.

Pheromones and Other Semiochemicals for Monitoring Rare and Endangered Species

Journal of Chemical Ecology, Journal Year: 2016, Volume and Issue: 42(9), P. 853 - 868

Published: Sept. 1, 2016

As global biodiversity declines, and conservation have become ever more important research topics. Research in chemical ecology for purposes has not adapted to address this need. During the last 10–15 years, only a few insect pheromones been developed studies, including identification application of specifically population monitoring. These investigations, supplemented with our knowledge from decades studying pest insects, demonstrate that monitoring other semiochemicals can be applied widely rare threatened insects. Here, I summarize ongoing research, outline potential applications pheromone-based studies research. Such include dynamics distribution changes, delineation current ranges, tracking range expansions contractions, determination their underlying causes. Sensitive selective systems further elucidate importance dispersal landscape movements conservation. Pheromone-based indicator species will also useful identifying hotspots, characterizing general changes response landscape, climatic, or environmental changes.
