“…Autogeny has been observed in several species of Culicidae (O'Meara & Kranisck 1970, O'Meara & Evans 1977, Tabanidae (Charlwood & Rafael 1980) and sandflies (Feliciangeli et al 1993, Brazil & Oliveira 1999. This is a phenomenon that occurs in haematophagous insects that allows for the development of eggs without a prior blood meal, depending on the insect's diet during the larval period (O'Meara & Kranisck 1970, Perondini et al 1975.…”

“…Autogeny has evolved in many dipteran insects, including species of mosquitoes (Cuculidae) (Sota, 1994), sandflies (Psychodidae) (Montoya‐Lerma, 1992), blackflies (Simuliidae) (Raastad & Solem, 1989), flesh flies (Sarcophagidae) (Baxter et al , 1973), horse flies (Tabanidae) (Charlwood & Rafael, 1980), and blowflies (Calliphoridae) (Readshaw & van Gerwen, 1983), as well as in the hemipteran family Reduviidae (Noriega, 1992). Some of these insects are pests or disease vectors; thus, autogeny is significant in both ecological and economic terms.…”

Frequency‐dependent and density‐dependent larval competition between life‐history strains of a fly, Lucilia cuprina

1. Competition was created between the larvae of two life‐history strains of the blowfly Lucilia cuprina (Wiedemann) that have different requirements for larval resource acquisition. Adult females of one strain had the ability to mature eggs in the absence of adult feeding (autogeny) whereas the other strain lacked this ability. Autogeny shifts the burden of resource acquisition from adults to larvae, potentially leading to greater competition at this earlier life history stage. 2. A replacement series was used to determine the per‐capita competitive effect between strains relative to the intra‐strain effect, and density‐ and frequency‐dependent variation in this per‐capita effect was then evaluated. Evidence was found of competitive superiority of autogenous larvae when they occurred at a low frequency and low density, but their competitive ability was lost or reversed at higher frequencies and densities. 3. A dynamic competitive environment created by frequency and density dependence can account for the maintenance of genetic diversity for major life‐history traits. Such competition may explain why autogeny is rare in field populations of L. cuprina even although underlying genetic variation for the trait seems to be present.

The literature on age-grading techniques of adult insects, published since 1968, is reviewed. The techniques described include those which deal with changes in the reproductive system, as well as somatic changes which take place with age. They also include techniques based on changes induced by wear and tear. Follicular relics found in different orders of insects are described, and their origin, fate and relative usefulness in age-grading studies are discussed. Attention is drawn to the formation of anomalous, or aberrant dilatations, particularly ones formed as a result of follicle resorption. The suitability of the various techniques to the study of different insect species is compared, and the advantages of using more than one type of age-grading method in the study of one species are discussed. Enough detail of each technique is given to permit field workers to choose and apply the technique most suitable for the study of the insect of their choice, and for the degree of accuracy required by them. Lists of species which have been studied by particular age-grading techniques, or combinations of them, are given. Finally, examples are cited of the types of problems entomologists have sought to solve, often successfully, using age-grading methods.
