The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp., in the USA. Although the assumption that phorid flies use fire ant alarm pheromones for host location is probably true, we demonstrated in a previous study the possible involvement of other ant semiochemicals in the response of P. tricuspis to fire ants. This study was conducted to determine the glandular sources and identity of the semiochemicals mediating this interaction… Expand

Fire ant alarm pheromone and venom alkaloids act in concert to attract parasitic phorid flies, Pseudacteon spp.
TLDR
The results suggest an additive rather than a synergistic effect of combining both chemicals, and a host location model is proposed for parasitic phorid flies involving the use of fire ant alarm pheromone and venom alkaloids as long range and short range attractants, respectively. Expand
Host preference in parasitic phorid flies: response of Pseudacteon curvatus and P. obtusus to venom alkaloids of native and imported Solenopsis fire ants
Pseudacteon curvatus and P. obtusus are two species of parasitic phorid flies (Diptera: Phoridae), introduced in the southern USA for biological control of Solenopsis fire ants (Hymenoptera:… Expand
Comparative responses of four Pseudacteon phorid fly species to host fire ant alarm pheromone and analogs
TLDR
Comparisons of electroantennogram (EAG) and behavioral responses of four Pseudacteon species confirm that multiple species of phorid flies use fire ant alarm pheromone as a host location cue, but the flies are not strongly attracted to the tested alkylpyrazine analogs of the alarm phersomone. Expand
Phorid fly, Pseudacteon tricuspis, response to alkylpyrazine analogs of a fire ant, Solenopsis invicta, alarm pheromone.
TLDR
It is proposed that fire ant alarm pheromones may act in tandem or synergistically with venom alkaloids to attract phorid fly parasitoids to fire ant workers. Expand
Comparing electroantennogram and behavioral responses of two Pseudacteon phorid fly species to body extracts of Black, Red and Hybrid imported fire ants, Solenopsis spp.
TLDR
The results of the EAG and behavior studies suggest that parasitic phorid flies utilize host derived non-polar compounds from worker ants extracted out by hexane for host location but not for host preference, since both fly species are not able to distinguish among the body extracts of the three fire ant species. Expand
Parasite Lost: Chemical and Visual Cues Used by Pseudacteon in Search of Azteca instabilis
TLDR
Results indicate that a pygidial gland compound, 1-acetyl-2-methylcyclopentane, is at least partially responsible for attracting phorid flies to their host. Expand
Pseudacteon Phorid Flies: Host Specificity and Impacts on Solenopsis Fire Ants.
TLDR
This review focuses on the mechanisms underlying host location, host preference, and host-size selection of Pseudacteon phorid flies and highlights their direct and indirect effects on fire ant populations. Expand
Title Cuticular Hydrocarbon Cues Are Used for Host Acceptance by Pseudacteon spp . Phorid Flies that Attack Azteca sericeasur Ants Permalink
Parasitoids often use complex cues to identify suitable hosts in their environment. Phorid fly parasitoids that develop on one or a few host species often use multiple cues, ranging from general to… Expand
Cuticular Hydrocarbon Cues Are Used for Host Acceptance by Pseudacteon spp. Phorid Flies that Attack Azteca sericeasur Ants
TLDR
It is shown, through behavioral observations in the field, that phorid flies are attracted to two crypticAzteca species, but only attack Azteca sericeasur, a short-range, host location cue used by P. lasciniosus (Diptera: Phoridae) to locate the ants. Expand
Behavioural response of the fungus gnat, Bradysia impatiens (Diptera: Sciaridae) towards certain edible mushrooms and saprophytic fungi
TLDR
The potential for the development of M. circinelloides in a push‐pull strategy to biocontrol this pest in edible mushroom cultivation is demonstrated. Expand

Behavioral and Electroantennogram Responses of Phorid fly Pseudacteon tricuspis (Diptera: Phoridae) to Red Imported Fire Ant Solenopsis invicta Odor and Trail Pheromone
TLDR
It is suggested thatFire ant thorax is likely the source of kairomones used as host location cues by P. tricuspis, and the hypothesis that fire ant worker trail pheromones are not likely used by the phorid fly is supported. Expand
Post-Release Host-Specificity Testing of Pseudacteon tricuspis, a Phorid Parasitoid of Solenopsis Invicta Fire Ants
TLDR
Tests of host specificity on introduced populations of Pseudacteon tricuspis found it to be highly host specific and pose no obvious threat to nontarget species. Expand

Pseudacteon phorids that parasitize the red imported fire ant, Solenopsis invicta Buren, in South America are not present in the introduced range of this pest species in the United States. Sequential… Expand
Response of the Egg Parasitoids Trissolcus basalis and Telenomus podisi to Compounds from Defensive Secretions of Stink Bugs
TLDR
The results indicate some degree of specialization in the response of two generalist parasitoid species toward defensive secretions of stink bugs. Expand
Response of the Ladybird Parasitoid Dinocampus coccinellae to Toxic Alkaloids from the Seven-spot Ladybird, Coccinella septempunctata
TLDR
Myrrhine, a stereoisomer of precoccinelline found in low amounts in C. septempunctata and in other ladybird species, was shown to be electrophysiologically active and significantly attractive. Expand
Rearing the decapitating fly Pseudacteon tricuspis (Diptera: Phoridae) in imported fire ants (Hymenoptera: Formicidae) from the United States
TLDR
The South American phorid fly Pseudacteon tricupis Borgmeier was imported into quarantine facilities in Gainesville, FL, to study its life history and determine if it could be reared on imported fire ant workers from North America and developed successfully, indicating that mass rearing for inoculative releases in the United States may be possible.

HOST-SPECIFIC ATTRACTION OF PSEUDACTEON FLIES (DIPTERA: PHORIDAE) TO FIRE ANT COLONIES IN BRAZIL
TLDR
Results demonstrate that P. tricuspis and P. litoralis are highly specific to saevissima complex fire ants and strongly indicate that they would pose little threat to native fire ants should they be released as biocontrol agents for imported fire ants in the United States. Expand
Fly parasitoid Megaselia opacicornis uses defensive secretions of the leaf beetle Chrysomela lapponica to locate its host
TLDR
Experiments indicate that host plant-derived defensive secretions are used by this parasitoid for host location, and adaptation of parasitoids to use defensivesecretions of hosts may selectively favor an increase in diet breadth in specialist herbivores. Expand
Protein components of fire ant venom (Solenopsis invicta).
TLDR
Venom of the fire ant ( Solenopsis invicta), long thought to contain only alkaloids, is shown to contain proteins, which undoubtedly accounts for the induction of anaphylactic reactions from stings. Expand
