AbstractUnder laboratory conditions adult feeding, ovipositional preference, daily fecundity and longevity, as well as larval and pupal development time and survival of the alfalfa blotch leafminer, were compared on Anchor, Vernal, Iroquois, and Saranac varieties of alfalfa. Although some significant differences were noted, no constant trends were evident when considering all parameters, and rmax values for A. frontella (Rondani) on the four varieties tested were very similar.Data from field plots confirmed that intervarietal differences of the varieties tested were not of sufficient magnitude to markedly affect the population dynamics of this pest species.

Beneficial Insect

The alfalfa leafcutting bee, Megachile rotundata (Fab.), is an important pollinator of alfalfa in western Canada and is widely utilized for alfalfa seed production (Richards 1984). As a beneficial insect, the alfalfa leafcutting bee must be considered, along with the honey bee, Apis mellifera L., as a non-target organism of importance in evaluations of potential microbial control agents for use against major insect pest species on the Canadian prairies.

Agromyza Frontella

Male size is an important parameter in mate choice for many species and has been associated with such female life-history parameters as increased fecundity or fertility and larger progeny (Phelan and Baker 1986; Savalli and Fox 1998, 1999; Brown 1999). In the alfalfa blotch leafminer, Agromyza frontella (Rondani), intraspecific larval competition may significantly influence the size of both males and females (Quiring and McNeil 1984a). The influence of female size on female reproductive success has been studied (Quiring and McNeil 1984b, 1984c), but to date, no attention has been given to the possible effects of male size. The objectives of this study were to determine if differences in male size, the result of intraspecific larval competition, affected male longevity and reproductive success, as well as various parameters of female reproduction.

AbstractThe alfalfa blotch leafminer, Agromyza frontella (Rondani), typically develops through three complete generations a year. It overwinters as a partially developed pupa that completes its development in mid-May. Three distinct adult flight periods occur: mid-May to mid-June, late June to late July, and early to late August. Eggs are deposited singly in alfalfa leaflets beneath the lower epidermis and on hatching, the larvae move toward the upper leaflet surface where they feed on the mesophyll and develop through three instars to form blotch mines, each representing about 27% of the leaflet area. The mature larvae emerge from the mines and drop to the soil to form light brown puparia, mainly in the top 2.5 cm of soil.Duration of each stage decreased with rise in temperature up to 25° but none of the stages survived 30°C. Developmental rates plotted against temperature gave highly correlated linear relationships for all stages. The theoretical threshold for the egg, larva, and pupa was 7°, 3°, and 4°C, respectively; thermal requirements for these stages were 55, 123, and 333°D, respectively.Survival of the larvae was higher in leaflets with solitary mines than in those with multiple mines; only 25% of the leaflets with two mines gave rise to two mature larvae. Three larvae seldom survived in a single leaflet.

Two related stereoselective syntheses of 3,7-dimethylnonadecane, a sex pheromone of the alfalfa leafminer, are described to show that pulegone can serve as a useful starting material for the preparation of chiral aliphatic isoprenoid compounds. The schemes are designed to place the stereogenic center of pulegone at C.3 in one synthesis and at C.7 in the other so that the optical properties of the products can be compared with one another and with the values calculated using Brewster's rules. Key words: chiral hydrocarbons, stereoselective synthesis, pheromone, Agromyza frontella.

The Relationship

In animals, the early-life environment influences growth and development, which can have lasting effects on life history and fitness into adulthood. We investigated patterns of growth, pupal development time, and their covariation, in wild antler fly larvae (Protopiophila litigata; Diptera: Piophilidae) of both sexes collected from three discarded moose antlers of varying size, chewing damage (used to infer relative age), and antler fly density. Males tended to be smaller and their pupation lasted longer than females. One of the antlers was highly attractive to adult antler flies, whereas the other two attracted few or none. Individuals from one antler of low attractiveness were smaller and took longer to eclose than individuals from either other antler, perhaps due to its high larval density. The relationship between body size and pupal development time also differed among antlers, being positively correlated in the most attractive antler and negatively correlated in the two other antlers.

Parasitoids manipulate the host metabolism for their own benefit by influencing its development and the direct or indirect result of it is the host death. This study aimed to observe the influence of parasitoidism of Paravilla sp. (Diptera, Bombyliidae) on the development of antlion larvae Myrmeleon brasiliensis (Návas, 1914) (Neuroptera, Myrmeleontidae). The specific objectives were to verify in which larval instars the parasitoid oviposition occurs, the influence of the parasitoid on the larval and pupal development time of M. brasiliensis, the differences in body length of the antlion larvae, as well as of the sex ratio of M. brasiliensis adults. For this, the larvae were differentiated in 1st, 2nd and 3rd instar and measures on body length (head-abdomen) and accompanied until the emergence of the adult. It was observed that the parasitoid Paravilla sp. attacked only the 2nd and 3rd instar larvae. The parasitoid Paravilla sp. oviposited only in 2nd and 3rd instars larvae. No significant differences were observed on larval development time, in the larval body length and in the adult sex ratio between groups of parasitized and non-parasitized M. brasiliensis larvae, however, was observed differences in the pupal development time of these two groups. Thus, we can conclude that the parasitoid Paravilla sp. influences the development time of M. brasiliensis pupal.
