Sample plots of 10 aerial traps per habitat type were set in two
sites containing a forest patch, a palm plantation and some agricultural land. Overall, 2,217 individuals belonging to 31 species were collected. Typical species of each habitat were identified with the IndVal method (Dufrêne and Legendre 1997). Species were categorized into three habitat-
groups: forest specialists (11 species), farmland and open habitat specialists (9 species) and ubiquitous, generalist species found in all habitats (5 species). Only six species were too rare for assessing habitat preference. Palm plantations host a low density of Cetoniinae with no unique species. However, species composition reveals that they
are used by forest specialist species that avoid open habitats like farmlands, therefore providing structural connectivity. Cetoniine flower beetles have potential as an indicator group, which can be used in multi-taxa approaches for habitat assessments in Africa. Using species-level
metrics, their response to habitat change is clear, including the response of common species. This method is selective, cost-effective in time and materials, and species identification is rather straightforward.10aBioindicators10aCommunity specialization10aCost-effectiveness10adiversity10aForest fragments10aOil palm1 aTOUROULT, J.1 aLe Gall, P.  uhttp://www.springerlink.com/content/h73gh4427211570k/01967nas a2200181   4500008004100000245015300041210006900194300001200263490000700275520121500282653002701497653002901524653001701553653002301570100001701593700002501610856015001635       2009                        eng d00aDiscovery of potent, unsuspected sampling disparities for Malaise and Möricke traps, as shown for Neotropical Cryptini (Hymenoptera, Ichneumonidae)0 aDiscovery of potent unsuspected sampling disparities for Malaise  a199-2060 v143 aMalaise and Möricke traps, universally used mostly to sample wasps and flies, are compared for the first time at genus level, focusing on Cryptini, one of the most diverse parasitoid taxa. Conclusions are supported by 10,706 man-hours of activities, 5,569 specimens from 20 Atlantic Forest and Amazon Forest localities, 4.81 Malaise trap-years and 89.09 Möricke trap-years. Substantial taxonomic and sexual biases were detected and quantified for Cryptini and for each of its studied genera. Möricke captured a proportion of Cryptini to other Ichenumonidae almost four times greater than Malaise. Most genera were captured mostly or exclusively by one of the traps only. Generally, Malaise collected 2.4 times more males than females, and 20% more species for males than females; Möricke yielded 2.4 times more females, and 2–4 times more species for females than males. The study scrutinizes and reaches beyond an allegedly known, but widely neglected problem. Data interpretation strongly suggests the necessity of sampling with both traps at once, under the risk that biodiversity investigations might otherwise continue to generate grossly biased results. Trap equivalence is discussed and quantified10abehaviour á gender á10aflight interception trap10asex-ratio á10ayellow pan trap á1 aAguiar, A.P.1 aSantos, Bernardo, F.  uhttps://insectafgseag.myspecies.info/en/content/discovery-potent-unsuspected-sampling-disparities-malaise-and-m%C3%B6ricke-traps-shown-neotropica
