A major cause for biodiversity may be biodiversity itself. As new species form, they may create new niches for others to exploit, potentially catalyzing a chain reaction of speciation events across trophic levels. We tested for such sequential radiation in the Rhagoletis pomonella (Diptera: Tephritidae) complex, a model for sympatric speciation via host plant shifting. We report that the parasi...

Microorganisms are acknowledged for their role in shaping insects' evolution, life history and ecology. Previous studies have shown that microbial communities harbored within insects vary through ontogenetic development and among insects feeding on different host-plant species. In this study, we characterized the bacterial microbiota of the highly polyphagous Mediterranean fruit fly, Ceratitis ...

The population dynamics of fruit fly Bactrocera zonata Saunders (Diptera: Tephritidae) was carried out by installing "Nauroji-Stonehouse Fruit Fly Trap" in the mango orchard organic farm, Navsari Agricultural University, Navsari, Gujarat, India during period 2021-22. B. prevailed throughout year with its peak activity from 14th SMW to 31st which coincided fruiting and harvesting fruits. maximum...

Bactrocera oleae (Rossi, 1790) (Diptera: Tephritidae) is the most dangerous insect pest of olive tree in Mediterranean region. This study was conducted Mascara region (North-West Algeria) during 2019-2020 season, order to monitoring flight activity B. by using Mc Phail type traps and evaluating infestation rate on two varieties (Sigoise Chemlal) fruits sampling. The data obtained indicated that...

Semi-field experiments were used to compare the curative activity of insecticides on spotted-wing drosophila (Drosophila suzukii (Matsumura) (Diptera: Drosophilidae)) and blueberry maggot (Rhagoletis mendax Curran (Diptera: Tephritidae)) in blueberry fruit. The organophosphate phosmet, the spinosyn spinetoram, and neonicotinoids imidacloprid, acetamiprid, and thiamethoxam showed significant let...

Insects form an extremely large group of animals and bear a consequently large variety of associated microbes. This microbiota includes very specific and obligate symbionts that provide essential functions to the host, and facultative partners that are not necessarily required for survival. The Tephritidae is a large family that includes many fruit pests such as the Mediterranean fruit fly (the...

The susceptibility of preimaginal and adult olive fruit fly, Bactrocera oleae (Gmelin) (Diptera: Tephritidae), to a strain of the mitosporic ascomycete Metarhizium brunneum (Petch) (Hypocreales: Clavicipitaceae) and the insecticidal activity of its crude extract to olive fruit fly adults were investigated. Strain EAMb 09/01-Su caused 60% mortality to B. oleae adults, with average survival time ...

Antennal morphology and funicular sensillae of male and female peach fruit flies, Bactrocera zonata (Saunders) (Diptera: Tephritidae), were studied with scanning electron microscopy (SEM). This study focused on the sensillae found on the antennal segments (scape, pedicel, and flagellum or funiculus that bears the arista) of B. zonata. Antennal segments of females tended to be larger than those ...

The melon fruit fly, Bactrocera cucurbitae Coquillett (Diptera: Tephritidae), is one of the important insect pests of fruits and vegetables. In order to monitor and control it effectively, it is necessary to know the potential geographical distribution of this pest. The ER (Eclosion rate) model was constructed from empirical biological data, and analyzed with ArcGIS. Based on the soil temperatu...
