Article Reference First records of a supercolonial species of the Tapinoma nigerrimum complex in Belgium (Hymenoptera: Formicidae)
In the summer of 2014, a highly supercolonial Tapinoma was discovered in Ostend, Belgium. This was the first time a Tapinoma species with an invasive behaviour was discovered outdoors in Belgium. The ant belongs to the most widely distributed of four recognized species of the Tapinoma nigerrimum complex and is the only known species being invasive in areas north of the Mediterranean zone. In a first attempt to eliminate the species, a Demand 10CS insecticide solution treatment was initiated in 2015. First results illustrate that this treatment might be efficient, however a long-term monitoring of the site and its neighbourhood are suggested.

Article Reference Do private coffee standards ‘walk the talk’ in improving socio-economic and environmental sustainability?
Private sustainability standards cover an increasingly large production area and involve an increasing number of farmers worldwide. They raise expectations among consumers about the economic, ethical and environmental implications of food production and trade; and attract donor funding to certification schemes. The sustainability impact of standards remains unclear as research focuses on either economic or environmental implications. We analyze both the socio-economic and environmental impacts of coffee standards in Uganda and show that these are not in line with expectations created towards consumers. We find that standards improve either productivity and farm incomes or biodiversity and carbon storage but fail to eliminate trade-offs between socioeconomic and environmental outcomes, even when combined in multiple certification. Our analysis is based on a unique combination of economic survey data and ecological field inventory data from a sample of certified and noncertified coffee farms. Our findings are relevant for farmers, food companies, policy-makers, donors and consumers. They imply that combining different standards in multiple certification is counterproductive; that the design of standards could improve to mitigate observed trade-offs between economic and environmental outcomes; and that this requires increased productivity within ecological boundaries, rather than a price premium and added control mechanisms through multiple certification

Article Reference IMPACT OF ANTS ON THE GROWTH AND PRODUCTIVITY OF LAMTO SAVANNA PERENNIAL GRASSES (COTE D’IVOIRE)
Lamto savanna soil known to have low agronomic value paradoxically has one of the highest grasses biomass productions in the world. During recent surveys, ant nest were encountered under some grass tufts and it as suggested that ants are able to influence the availability of resources for these grasses and also other organisms. An interaction is suspected between these savanna grass tufts and their associated ants. Three grasses species Andropogon schirensis, Hyparrhenia diplandra and Loudetia simplex were chosen to inventory ant communities associated with grass tufts and to assess the influence of ant communities on growth and productivity of perennial grasses. Three study sites were chosen and each was subdivided in two experimental plots of 2500 m². By systematic digging out method we were collected 38 ant species under grass tufts. They belong to 19 genera and 7 sub-families. Lamto herbaceous stratum was dominated by Camponotus acvapinensis. Diameter measures of grass tufts base at ground level, have allowed establishing the link between the size of ant nest and grass tufts size. Pearson coefficient r ranged no correlation between the size of ants nest and grass tufts size. The association rate with ants of one of the grasses Hyparrhenia diplandra was greater than for two other grasses studied Andropogon schirensis and Loudetia simplex (54.208 % versus 49.433 %, and 38.496 % respectively). Parameters such as grasses height, diameter (at ground level, and 10 cm above), dry biomass and seeds production were assessed. The results showed that Hyparrhenia diplandra with ant nest recorded the best results of growth and productivity. Association with ants nest is beneficial for the growth and productivity of Lamto perennial grasses.
