“…Among other agromyzids, A . frontella has been reported to have a very similar sex ratio, 1 male: 1.2 females (HENDRICKSON and BARTH, 1978), while L. trifolii had a sex ratio of 1 male: 1 female (PARELLA, 1987). The insignificant tendency of a slightly faster development of males over females in this investigation was not confirmed in the unpublished emergence trap material.…”

The median developmental rates for all immature stages of Chromatomyia fuscula (Zett.) increased linearly between 9 and 21'C. An exponential and a Cobb-Douglas model was tested, but gave only as good as or slightly better fits than the linear regression model. The lower thermal developmental thresholds for all stages were 3.0 0.5"C. Both sexes required 400 degree-days above 3.0"C for the total development from egg to adult emergence. At the relatively low temperatures investigated, C.

“…Throughout the lifetime of all females the alfalfa stems, which serve as both feeding and oviposition sites (Hendrickson and Barth 1978), were changed daily and the eggs were counted to evaluate both age-specific and total fecundity. Stems were held in water for an additional 9 days to determine the incidence of egg eclosion, as egg development requires approximately 6 days at 20°C (Mellors and Helgesen 1978). Females that laid no fertile eggs were considered as unmated, although it is possible that unsuccessful mating may have occurred.…”

Longevity and fecundity of mated and unmated Agromyza frontella females were positively related to pupal weight which was determined by the degree of intraspecific larval competition to which individuals had been subjected. The incidence of egg eclosion for mated females was also positively correlated to pupal weight. Unmated females lived longer, started ovipositing later following emergence, and had a lower mean daily and total fecundity than mated females, which supports the hypothesis of a trade-off between reproductive output and longevity. However, a positive relationship existed between fecundity and longevity for both mated and unmated females, as well as between high early egg production and longevity for mated females.

“…Field-curing of hay did not significantly increase larval survival under the "management" harvest treatment (Table I); only a few mature larvae that were present at cutting survived (Fig. This increase may have been compounded by moderation of soil temperatures beneath windrows, thereby decreasing pupal mortality (Mellors and Helgesen 1978). However, by 10% bloom, mature or nearly mature larval populations had exceeded 261 stem and some had already vacated their mines.…”

“…75% to 25%. Information is needed since harvest schedule modification is a key component of leafminer pest management in the northeastern United States (Spencer 1974;Bremer 1976); only the soil-dwelling pupae survive crop harvest (Mellors and Helgesen 1978), and timing in relation to larval development determines their density in the soil. Andaloro (1981) hypothesized that survival of the alfalfa blotch leafminer, Agromyza frontella (Rondani), may be similarly influenced by this practice.…”

Can. Ent. 115: 89-91 (1983) Simulated windrow experiments revealed that 32.0k 8.4% or 3rd-instar Agromyza frontella (Rondani) larvae completed development and formed puparia in alfalfa hay during field curing; 1st-and 2nd-instar larvae suffered almost complete mortality. Under a management schedule where first harvest was at 10% bloom, adult emergence was 45% higher from soil under windrowed hay than from soil under strips immediately raked. Development of A. frontella in hay being field-cured is discussed in relation to crop pest management and crop management options.
