“…While this family accommodates both generalist and specialist species, the polyphagous Mediterranean fruit fly (medfly, Ceratitis capitata Wiedemann) can exploit over 350 plant species from 65 families (Liquido et al, 1990). In contrast to the larva which must deal with a fixed resource during its development, the adult can balance its diet from a diversity of food sources (Demirel, 2007; Leftwich et al, 2017). The medfly harbours a gut microbiome that is in part transmitted vertically between generations, and in part acquired from the environment, varying between individuals raised under similar conditions (Behar, Jurkevitch, & Yuval, 2008; Behar, Yuval, & Jurkevitch, 2008a; Behar, Yuval, & Jurkevitch, 2008b; De Cock et al, 2020).…”

1. Polyphagous, holometabolous insects adapt to rapid diet shifts imposed by their ecology and their life cycle. One shift is linked to development, as larvae and adults usually dwell and feed in different environments, using different resources.The second is caused by changes in larval hosts, often occurring at each generation. Studies show that the insect's microbiome also changes in relation to development and larval host. However, parental and larval host contributions to its structure and trans-generational dynamics remain uncharted.2. We investigated the sources of variation of the microbiome of the highly polyphagous Mediterranean fruit fly by tracking microbiome structure and its potential functional impact in fly lineages over generations and fruit host shifts, using 16S rRNA gene amplicon single variant analysis.3. Bacterial community alpha-diversity expanded and contracted cyclically in a life stagedependent manner with the mothers' microbiome community 'resetting' to the same structure across generations. Expansion occurred at the larval stage, while alphadiversity decreased in tenerals, and significantly in mothers. In contrast, richness was highest in mothers, with rare taxa expanding in larvae depending upon fruit type. 4. Metabolic predictions using PICRUSt pointed to increased metabolism of vitamins in mothers, and of aromatic compouds in larvae and tenerals, while indicator species analysis suggested fruit host composition-dependent potential functional adaptations. 5. Our data indicate lineage, fruit host and their interactions as the main sources of microbiome variation and provide examples of possible metabolic developmental and ecological adaptations. Taken together, these data support the hypothesis that microbiome diversity and microbiome-driven local adaptations act as a mechanism sustaining polyphagy.

“…These results are in agreement with the functional role that olfactory sensitivity for host-plant odors plays in both sexes. In fact, males look for host plants where they can induce lekking to attract females for mating, while females visit host plants with the aim of copulating and finding suitable sites for oviposition [44,68,69]. The lack of differences between males and females in the EAG responses to host-plant odors has also been reported in other insects such as Rhagoletis pomonella, Dacus dorsalis and Iragoides fasciata [70][71][72].…”

Differences in the Olfactory Sensitivity of Ceratitis capitata to Headspace of Some Host Plants in Relation to Sex, Mating Condition and Population

The Mediterranean fruit fly, Ceratitis capitata Wied., is among the most serious pests in horticulture worldwide, due to its high reproductive potential, difficulty of control and broad polyphagy. The aim of this study was to measure—by means of the electroantennogram recordings— the antennal olfactory sensitivity of virgin, mated, male, female, lab-reared and wild C. capitata following stimulation with fruit and leaf headspace of some host-plants: clementine, orange, prickly pear, lemon and apple. The results show that: (a) lab-reared mated males are more sensitive to host-plant fruit and leaf headspace than females, while the opposite was true for wild insects; (b) antennae of wild virgin males were more sensitive than the mated ones, while no difference was observed among lab-reared medflies; (c) lab-reared virgin females were more sensitive than mated ones, while few differences were found within wild medflies; (d) in mated insects, lab-reared males were more sensitive to both host-plant fruits and leaves than the wild ones, while the opposite was found for females. Taken together, these results show that the olfactory sensitivity to host-plant odors differs between virgin and mated and lab-reared and wild flies.

The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most important fruit pests throughout the world (White & Elson-Haris, 1994;Demirel, 2016;Demirel & Akyol, 2017;Demirel et al, 2018;Demirel, 2019a,b). The Medfly is a polyphagous species attacking over 350 different hosts plant (Weems, 1981;Liquido et al, 1991).…”

The study was conducted to determine infestation rates of medfly on common guava, Psidium guajava L. (Myrtaceae), fruits in Hatay province of Türkiye. During the study, a different number of the common guava fruits were collected at University of Hatay Mustafa Kemal Research Center in Field 49. They were brought to the laboratory, placed in three plastic container, and each container put into three different mesh screen cages at room temperature. For each of the sampling year, the adults of medfly emerging from the infested fruits were counted in a three-mesh screen cages. Additionally, medfly infestation rates were evaluated as percentage by examining all fruits in plastic cups in each of the cages. As a result of four-year investigations, this pest was found on P. guajava fruits in all sampling years. Totals of 3240 medfly adults in 2016, 4161 medfly adults in 2017, 4621 medfly adults in 2019, and 2982 medfly adults in 2020 were counted in three mesh screen cages. In 2016, a total of 600 guava fruit samples were collected during the study period, of which 255 fruits (42.5%) were infested by medfly. In 2017, a total of 450 guava fruit samples were collected during the study period, of which 352 fruits (78.22%) were infested by medfly. In 2019, a total of 870 guava fruit samples were collected during the study period, of which 625 fruits (71.84%) were infested by medfly. In 2020, a total of 689 guava fruit samples were collected during the study period, of which 554 fruits (81.41%) were infested by medfly. The highest percentage infested rates was recorded as 81.41 in 2020, followed by 78.22 in 2017, 71.84 in 2019 and 42.5 in 2016.
