Ladybird (Coleoptera : Coccinellidae) dispersal in experimental fragmented alfalfa landscapes
(CZECH ACAD SCI, INST ENTOMOLOGY, 2005)
Habitat fragmentation may affect the dispersal behaviour of individuals across the landscape. If there is a high boundary contrast between the remaining fragments and the matrix, individuals should tend to stay inside the ...
Predation and reproductive output of the ladybird beetle Stethorus tridens preying on tomato red spider mite Tetranychus evansi
(SPRINGER, 2009)
Predatory behaviour and reproductive output of the ladybird beetle Stethorus tridens Gordon as function of the tomato red spider mite (TRSM), Tetranychus evansi Baker & Pritchard, densities was investigated in the laboratory. ...
Cushion plants as microclimatic shelters for two ladybird beetles species in alpine zone of central Chile
(INST ARCTIC ALPINE RES, UNIV COLORADO, 2006-05)
High mountain environments are highly stressful for insect survival. It has been suggested that small microtopographic variations generating less stressful microclimatic conditions than the surrounding environment would ...
Induced-feeding bioassays for detection of Bacillus thuringiensis insecticidal activity against Epilachna paenulata (Coleoptera).
(Pesquisa Agropecuária Brasileira, Brasília, v.45, n.4, p.430-432, abr. 2010, 2014)
Interspecific exploitative competition between Harmonia axyridis and other coccinellids is stronger than intraspecific competition
(Academic Press Inc., 2019)
The invasion of Harmonia axyridis has had negative consequences on coccinellid assemblages, with a decline in abundance and diversity, but the coexistence of invasive and resident species may depend on the strength of ...
The positive association between natural vegetation, native coccinellids and functional diversity of aphidophagous coccinellid communities in alfalfa
(Blackwell Publishing Ltd, 2021)
© 2021 The Royal Entomological SocietyA greater taxonomic and functional diversity of natural enemies in agroecosystems is frequently positively associated with more effective pest control, due to the complementarity of ...
The invasive coccinellid Harmonia axyridis (Coleoptera: Coccinellidae) is a less suitable host for parasitism than resident species
(Pontificia Univ Católica Chile, Fac Agronomía Ingeniería Forestal, 2020)
Harmonia axyridis (Pallas) has invaded most continents
in the world, including South America. In Chile, it became invasive after 2010, turning into a
dominant species in coccinellid guilds in alfalfa crops, where it ...
