“…After mating and landing, dealation is relatively fast, usually within 1 h (Toom et al , 1976) to 4 h (Markin et al , 1971, 1972). Dealation of mature alate virgin (MAV) females can occur (even in the parent colony) if the queen is removed or if MAV‐females are removed from the queen’s influence (Fletcher & Blum, 1981a, b).…”

Newly‐mated Solenopsis invicta flight queens cast (shed) their wings within 24 h. An examination of their flight muscle cells reveals numerous apoptotic (terminal deoxynucleotidyl transferase mediated dUTP nick end labelling positive) nuclei. By contrast, flight muscle cells of mature alate virgin (MAV) females removed 24 h earlier from a managed laboratory colony exhibit neither wing casting nor the presence of apoptotic nuclei. Using MAV‐females, the initiation of flight muscle apoptosis and wing casting is compared with artificial mating using seminal fluid with sperm, seminal fluid with no sperm, saline as a negative control, the mating flight as simulated in the laboratory, elevated CO2 exposure, application of methoprene (a juvenile hormone analogue), or injection of 20‐hydroxyecdysone. Numerous apoptotic nuclei are revealed in the flight muscle cells of mated dealate females 24 h after a natural mating flight but not in MAV‐females controls. Only artificial mating of MAV‐females reveals a similar pattern of apoptotic nuclei flight muscle 24 h after insemination. None of the other factors tested induces flight muscle cell apoptosis in MAV‐females. Methoprene dissolved in methyl ethyl ketone, at a concentration of 0.44 ng per μL per ant, stimulates 90% of MAV‐females to shed their wings within 24 h, as opposed to 10% or less wing shedding for the methyl ethyl ketone control and all other treatments.

Insemination‐induced histolysis of the flight musculature in fire ants (solenopsis, spp.): An ultrastructural study

The fine structure of the insemination-induced flight muscle degeneration (histolysis) in the queen fire ant (Solenopsis spp.) has been investigated. Within 2 hours post-insemination, degenerative changes are detectable in the most peripheral fasciculi of the fibrillar flight muscle. Histolysis proceeds internally with time. Myofibril (sarcomere) dissolution begins with myofilament breakdown and continues until only free Z-line material remains. The latter subsequently disappears leaving, at the terminal stages, only nuclei, lamellar bodies (myelin figures), and tracheoles as residual myoid elements. Lysosomes and/or phagocytes do not appear to play a primary role in the initiation and continuance of this process.
