Supercolonial structure of invasive populations of the tawny crazy ant Nylanderia fulva in the US
(BioMed Central, 2018-12)
Background: Social insects are among the most serious invasive pests in the world, particularly successful at monopolizing environmental resources to outcompete native species and achieve ecological dominance. The invasive ...
Local dynamics of worker activity of the invasive Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) wasps in Argentina
(Wiley Blackwell Publishing, Inc, 2015-11)
1. The abundance of insects depends essentially on the reproductive success of individuals. In social insects, however, the abundance of sterile workers outside a nest depends on colony size but is also determined by ...
The failed invasion of Harmonia axyridis in the Azores, Portugal: Climatic restriction or wrong population origin?
(Wiley, 2020)
We tested two questions: (i) whether the climatic conditions of the Azorean Islands in Portugal may have restricted the invasion ofHarmonia axyridisacross this archipelago and (ii) determine what population of this species ...
Infection and invasion mechanisms of Trypanosoma cruzi in the congenital transmission of chagas' disease: A proposal
(Society of Biology of Chile, 2010)
Chagas' disease is produced by the haemophlagelated protozoan Trypanosoma cruzi and transmitted by haematophages insects such as Triatoma infestans (vinchuca). Due to vector control, congenital transmission gains importance ...
Foliar herbivory and its effects on plant growth in native and exotic species in the Patagonian steppe
(Springer Tokyo, 2012-09)
Studies of herbivory and its consequences on the growth of native and exotic plants could help elucidate some processes involved in plant invasions. Introduced species are likely to experience reduced herbivory in their ...
Behavioural responses of Vespula germanica (Hymenoptera: Vespidae) wasps exposed to essential oils
