“…The top portion of mango fruit ripens earlier than the middle and the bottom, and thus has a softer pericarp than the other portions (at least for ripening fruit; Table 1). Firmness is considered to be a limiting factor for oviposition of female fruit flies (Seo et al 1982;Messina and Jones 1990;Balagawi et al 2005) and is possibly influencing adult preference in the B. dorsalis / mango system. We do note, however, that in this study we report only the fruit characteristic of firmness and TSS as possibly factors influencing oviposition site selection.…”

“…Fruit flies are well documented as preferring hosts with softer skins and/or flesh (Seo et al 1982;Messina and Jones 1990;Balagawi et al 2005;Rattanapun et al 2009). Preference for the top of fruit as an oviposition site may thus be a direct mechanical, or longer-term evolved response, to the fact that a host fruit is, or likely to be, softer at the top.…”

“…Another mechanism, and the one pursued in this paper, relates to host ripening. Fruit flies are known to preferentially oviposit into ripe over unripe fruit (Seo et al 1982;Messina and Jones 1990;Jang and Light 1991;Messina et al 1991;Vargas et al 1995), while larvae perform better in ripe fruit (Joachim-Bravo et al 2001;Fontellas-Brandalha and Zucoloto 2004). Better performance in ripe fruit may be due to nutritional status (e.g., higher sugar and lower starch levels; Bidwell 1979; Medlicott and Thompson 1985), but may also be due to changes in allelochemicals.…”

For fruit flies, fully ripe fruit is preferred for adult oviposition and is superior for offspring performance over unripe or ripening fruit. Because not all parts of a single fruit ripen simultaneously, the opportunity exists for adult fruit flies to selectively choose riper parts of a fruit for oviposition and such selection, if it occurs, could positively influence offspring performance. Such fine scale host variation is rarely considered in fruit fly ecology, however, especially for polyphagous species which are, by definition, considered to be generalist host users. Here we study the adult oviposition preference/larval performance relationship of the Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), a highly polyphagous pest species, at the ''within-fruit'' level to see if such a host use pattern occurs. We recorded the number of oviposition attempts that female flies made into three fruit portions (top, middle and bottom), and larval behavior and development within different fruit portions for ripening (color change) and fully-ripe mango, Mangifera indica L. (Anacardiaceae). Results indicate that female B. dorsalis do not oviposit uniformly across a mango fruit, but lay most often in the top (i.e., stalk end) of fruit and least in the bottom portion, regardless of ripening stage. There was no evidence of larval feeding site preference or performance (development time, pupal weight, percent pupation) being influenced by fruit portion, within or across the fruit ripening stages. There was, however, a very significant effect on adult emergence rate from pupae, with adult emergence rate from pupae from the bottom of ripening mango being approximately only 50% of the adult emergence rate from the top of ripening fruit, or from both the top and bottom of fully-ripe fruit. Differences in mechanical (firmness) and chemical (total soluble solids, titratable acidity, total nonstructural carbohydrates) traits between different fruit portions were correlated with adult fruit utilisation. Our results support a positive adult preference/offspring performance relationship at within-fruit level for B. dorsalis. The fine level of host discrimination exhibited by B. dorsalis is at odds with the general perception that, as a polyphagous herbivore, the fly should show very little discrimination in its host use behavior.

“…Studies have found that the response of Anastrepha suspensa (Loew) to proteinaceous odors and distance of attraction varied with sexual maturity of the females (Kendra 2009;Kendra et al 2010). Physiological age and parity have not yet been investigated in the oriental fruit fly, a major economic pest in tropical and subtropical fruit-producing areas in Asia and Hawaii (Seo et al 1982;Vargas et al 1983;Mau et al 2007). Suitable tools are needed in order to assess the physiological age of a targeted population for optimal timing of application of food-based attractants.…”
