SCIENTIFIC NOTE Presence of the Fire Ant Solenopsis invicta (Westwood) (Hymenoptera: Formicidae) Stimulates Burrowing Behavior by Larvae of the Sandfly Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae)

چکیده
The sandfly Lutzomyia longipalpis (Lutz & Neiva) vectors leishmaniasis in the neotropics. Although much is known about the biology of adult flies, little is known about interactions with its natural enemies. Here, we examined behavior of larvae of L4 L. longipalpis on a soil substrate when exposed to the fire ant Solenopsis invicata (Westwood). When ants were absent, most larvae tended to remain at or close to the soil surface, but when ants were present the larvae burrowed into the soil. Sandflies seek refuges in the presence of generalist predators, thus rendering them immune to attack from many potential enemies.

INTRODUCTION We report the first find of Lutzomyia longipalpis in the State of Paraná, Brazil. METHODS The specimens were captured in the urban area of the municipality of Foz do Iguaçu, with Falcão light traps, in domiciliary and peridomiciliary areas of 61 properties, on two consecutive nights from 18:00 to 06:00hs in March 2012. RESULTS We captured 40 specimens of Lu. longipalpis and 54 ...

We tested the host specificity of two South American Pseudacteon phorid flies, P. obtusus Borgmeier and P. borgmeieri Schmitz, on North American colonies of the red imported fire ant, Solenopsis invicta Buren, and the tropical fire ant, S. geminata (F.). Sequential host specificity tests conducted in the laboratory indicated that P. obtusus was highly specific to S. invicta . In individual tria...
متن کاملPhorid flies, Pseudacteon spp. (Diptera: Phoridae), affect forager size ratios of red imported fire ants Solenopsis invicta (Hymenoptera: Formicidae) in Texas.
Multiple species of Pseudacteon phorid flies (Diptera: Phoridae) are currently being released throughout the southern United States to aid biological control of red imported fire ants, Solenopsis invicta Buren (Hymenoptera: Formicidae). It is anticipated that these flies will interfere with S. invicta foraging, allowing native ant assemblages to outcompete S. invicta for available resources. N...
متن کاملRaft Formation by the Red Imported Fire Ant, Solenopsis invicta
The raft behavior of the invasive red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), has been documented for over a century. However, no rigorous tests have been performed elucidating the structure, limits, and important characteristics of this behavior. Rafting makes S. invicta competitive in both native and foreign environments. Further understanding of this behavior w...
متن کاملDiscovering Pheromones of the Red Imported Fire Ant (Solenopsis invicta Buren): A Review and Proposed New Target for Pheromone Disruption1
A method is described for discovering pheromones of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), using affinity chromatography with the pheromone-binding proteins of the ant. Proteins in the pheromoneand odorant-binding protein family, which are abundant in moths and other insect species, are not apparent in fire ant antennae. Two other types of hydrophobic lig...
