1 When, for instance in Solenopsis, the food source is so large that many ants are needed, mass-acting pheromones are released.

2 The discovery of the cryptic lineages in P. solenopsis complex is helpful for its accurate identification and the future research in its invasion ecology.

3 A species of fire ant called Solenopsis invicta originated in the rainforests of Brazil.

4 We unexpectedly found that there were two divergent clades in the mealybug species, P. solenopsis, based on the phylogenetic tree.

5 The effects of different surfaces on the foraging efficiency of Solenopsis invicta workers were observed.

6 The aim of the paper was to study on the potential distribution area of invasive alien pest red imported fire ant, Solenopsis invicta Buren in China.

7 Objective To test the efficacy of sulfluramid bait against Solenopsis invicta in gardens and common greenbelt.

8 These results will support theoretically for risk analysis of Solenopsis invicta potential disperse in China.

9 The present invention discloses a contact poisoning powder for killing solenopsis invicta Buren with high killing rate.
