    Notes: Abstract Male apple maggot flies spend considerable time residing on individual host fruit as territories on which they force-copulate arriving females in search of oviposition sites. Here, we present evidence from investigations in nature and the laboratory that shows the propensity of males to reside on a hawthorn or apple fruit as a territory is significantly modifiable through prior experience with fruit and, hence, involves learning. Previous studies revealed that after a female apple maggot fly, Rhagoletis pomonella, arrived on a host hawthorn or apple fruit, its propensity to accept or reject that fruit for egg-laying was similarly modifiable through prior fruit-exposure experience and also involved learning. We discuss how host fruit learning in males and females, in concert with genetic-based differences in host fruit residence and acceptance behavior between populations of flies originating from hawthorn and apple, could give rise to a reduction in gene flow between populations of flies on these two host types.

    How well can relative specialistRhagoletis flies learn to discriminate fruit for oviposition? (1993)
    Springer
    Journal of insect behavior 6 (1993), S. 167-176 
    Details
    ISSN: 1572-8889
    Keywords: learning ; oviposition ; specialist insects ; generalist insects ; Rhagoletis

    Topics: Biology
    Notes: Abstract We show that blueberry maggot females [Rhagoletis mendax(Curran)], apple maggot females [Rhagoletis pomonella(Walsh)], and walnut husk fly females [Rhagoletis suavis(Loew)], all relative specialists in range of fruit species attacked in nature, are able to learn to discriminate between types of fruit in which they oviposit. It appears, however, that these relative specialists express less capacity to learn fruit characters than relative generalist tephritids. This difference in expression of learning ability may be associated in part with differences in assignments species are asked to learn. Apparent differences in learning capability between relative specialist and relative generalist tephritids may therefore depend as much upon differences in the physical and chemical nature of host fruit as upon species differences in the adaptive value of learning.

    Learning in oviposition site selection by Ceratitis capitata flies (1986)
    Springer
    Entomologia experimentalis et applicata 40 (1986), S. 47-51 
    Details
    ISSN: 1570-7458
    Keywords: Ceratitis capitata ; learning ; conditioning ; oviposition
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Description / Table of Contents: Résumé Dans la même population sauvage de C. capitata, on a observé des différences significatives dans la tendance à essayer de pondre dans divers types de fruits. Les faits rapportés suggèrent qu'un apprentissage pendant la ponte sur un type de fruits conditionne la femelle à cet hôte, et influe sur les réponses de la femelle à d'autres hôtes lors de rencontres ultérieures.
    Notes: Abstract Significant differences in propensity to attempt oviposition into various types of fruit were found among Mediterranean fruit flies, Ceratitis capitata, from the same wild population. Evidence presented suggests repeated exposure to one host fruit type conditions females to that host, and influences female response to other hosts in future encounters. Reversibility of conditioning was also demonstrated. Learning to refuse a novel host type is indicated as being more important than learning to accept a familiar host type in medfly conditioning to hosts.
