Phorid Fly

Megaselia halterata (Wood) (Diptera: Phoridae) is a pest of commercial mushroom production in North America and Europe. Compost or casing materials treated with experimental insecticides were placed in commercial mushroom growing rooms that were heavily infested with M. halterata. Control was determined by comparing emergence from treated material with that from untreated material. As a compost treatment, the following were ineffective: resmethrin, fenvalerate, permethrin, Lily-7063, and triflumuron. Diflubenzuron was effective only at high doses. Acephate, chlorpyrifos, deltamethrin, diazinon, dimethoate, ethoprop, fenitrothion, and methoprene were effective. As casing treatments malathion, triflumuron, and diflubenzuron were ineffective. Dimethoate, diazinon, acephate, chlorpyrifos, deltamethrin, ethoprop, fenitrothion, and methoprene were effective.

Duration times were determined for Pseudacteon curvatus Borgmeier pupae subjected to various temperature regimes. Pupae that had initially developed 12–15 d in parasitized fire ant, Solenopsis invicta Buren, workers held at ~27°C were collected and subsequently held at different temperature regimes. Pupae exposed to a temperature of 26.7°C had the earliest peak fly emergence 15 d later. Pupae exposed to a lower temperature of 18.3°C for 12 or 19 d and then exposed to a temperature of 26.7°C required an additional 7 and 11 d to peak fly emergence, respectively. At 18.3°C peak fly emergence was delayed an additional 20 d. At 10°C for 12 or 19 d followed by 26.7°C, peak fly emergence was delayed an additional 12 and 18 d, respectively. Holding pupae at 10°C for 54 d followed by 26.7°C delayed peak fly emergence by an additional 51 d with a correspondingly high mortality. Fly survival rates tended to decrease as peak emergence was delayed. Models that predict fly emergence when pupae are held at reduced temperatures will prove useful in rearing programs where extended storage of phorid fly pupae is necessary for optimizing releases.

Phorid Fly

Myrmecophiles (i.e. organisms that associate with ants) use a variety of ecological niches and employ different strategies to survive encounters with ants. Because ants are typically excellent defenders, myrmecophiles may choose moments of weakness to take advantage of their ant associates. This hypothesis was studied in the rove beetle, Myrmedonota xipe , which associates with Azteca sericeasur ants in the presence of parasitoid flies. A combination of laboratory and field experiments show that M. xipe beetles selectively locate and prey upon parasitized ants. These parasitized ants are less aggressive towards beetles than healthy ants, allowing beetles to eat the parasitized ants alive without interruption. Moreover, behavioural assays and chemical analysis reveal that M. xipe are attracted to the ant's alarm pheromone, the same secretion used by the phorid fly parasitoids in host location. This strategy allows beetles access to an abundant but otherwise inaccessible resource, as A. sericeasur ants are typically highly aggressive. These results are the first, to our knowledge, to demonstrate a predator sharing cues with a parasitoid to gain access to an otherwise unavailable prey item. Furthermore, this work highlights the importance of studying ant–myrmecophile interactions beyond just their pairwise context.
