Abstract Ceratitis capitata (Diptera: Tephritidae) is a highly polyphagous species and seriously pest with significant economic importance, having great number of studies focused in its management. Recently, there has been surge interest the symbiotic relationship between gut bacteria their insect hosts. In this context, objective work was to evaluate role microbiota on aposymbiotic wild medfly adult sexual behaviour, especially mate choice mating success. We also latency time, sperm...
Abstract Ceratitis capitata (Wiedemann) is a cosmopolitan pest of economic importance. It controlled by using the Sterile Insect Technique (SIT), which involves rearing and release sterile males destined to mate with wild females, causing generation‐to‐generation suppression. Medflies are colonized microorganisms, primarily Enterobacteriaceae, genera Klebsiella Enterobacter being most common. Such microbiota contributes host fitness. During SIT, diet antibiotics irradiation for sterility...
Abstract Background Maize ( Zea mays L.) is the most widely cultivated cereal in world. The introduction of Bt gene and development sweet corn varieties with softer pericarp has led to emergence new pests genus Euxesta (Diptera: Ulidiidae), previously considered as secondary invaders. In Argentina, eluta mazorca predominate. Some control measures are being implemented; however, no biorational strategies have been developed date. With aims at developing effective monitoring traps, this study...
Abstract Among phytophagous insects, life history often evolves as a strategy to cope with seasonality in host plant availability. Whereas specialization leads dormancy, aestivation, or longevity, polyphagous species bridge between periods of availability by exploiting alternative plants. The aim the present work was characterize histories four specialist and generalist uni‐ multivoltine frugivorous fruit flies – Ceratitis capitata Wiedemann, Anastrepha fraterculus Rhagoletis blanchardi...
Methoprene, a juvenile hormone analog, is used to accelerate sexual maturation in males of species economic importance support the sterile insect technique (SIT). In SIT, mass-reared are released into field and need survive until they reach maturation, find wild female, mate with her then induce female refractoriness, so she will not remate counterpart. The use methoprene shortens time between release copulation. However, South American fruit flies, Anastrepha fraterculus, ability...
Abstract The Mediterranean fruit fly Ceratitis capitata is a globally invasive pest, often controlled with the sterile insect technique (SIT). For SIT, mass-rearing of target followed by irradiation are imperatives. Sterile males less able to inhibit female remating and transfer number sperm, even could affect male reproductive organs, consequences for their ability remating. On other hand, age modulate response after mating. Here, we evaluated quality genetic sexing strain Vienna-8-tsl...
Promiscuous mating systems provide the opportunity for females to bias fertilization toward particular males. However, distinguishing between male sperm competition and active female choice is difficult species with internal fertilization. Nevertheless, that store use of different males in storing structures where are able expel all or part ejaculates after copulation may be We report a series experiments aimed at providing evidence Euxesta eluta (Hendel), ulidiid fly expels consumes...
Abstract Jacaric acid, a conjugated linolenic acid (CLNA) present in jacaranda oil (JO), is considered potent anticarcinogenic agent. Several studies have focused on its biological effects, but the metabolism once consumed not clear yet. The aim of this work was to evaluate effects two different daily doses JO serum parameters and fatty (FA) profile mice tissues after 4 weeks feeding. No significant changes body weight gain, food intake, or tissue were determined 0.7 2 ml/kg supplementation...
Malpighian tubules (MTs) are arthropod excretory organs crucial for the osmoregulation, detoxification and excretion of xenobiotics metabolic wastes, which include tryptophan degradation products along kynurenine (KYN) pathway. Specifically, toxic intermediate 3-hydroxy (3-HK) is metabolized through transamination to xanthurenic acid or in synthesis ommochrome pigments. Early investigations Drosophila larval fat bodies revealed an intracellular autofluorescence (AF) that depended on...
Abstract In insects, aging produces deterioration in physiological and cellular functioning, affecting their reproductive potential. Anastrepha fraterculus Ceratitis capitata are two fruit fly species where overwintering adults resume activity spring, giving old individuals the possibility of mating with young adults. Most age studies focus on male capacity; however, we lack information how interaction between ages both sexes can determine post‐mating processes. Here, studied sex effects (i)...
Abstract With the purpose of broadening knowledge on evolution life history strategies and behaviour fruit flies within tribe Carpomyini, natural mating poorly known species Rhagoletotrypeta pastranai Aczél, are described for first time. Larvae R. were recovered from infested Celtis tala Gillies ex Planch iguanaea (Jacq.) Sarg. during a 2-month fruiting period. Adults emerged pupae after an average 144.9 ± 3.9 days females 143.2 3.38 males, suggesting that most individuals became dormant....
Abstract Plant‐derived volatiles can have positive or negative effects on insects. Exposure to of guava ( Psidium guajava L.) (Myrtaceae) enhances male mating success in the South American fruit fly, Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae), an important pest various fruits. These therefore be used as a post‐teneral, pre‐release supplement sterile insect technique (SIT) programs. In SIT, mass‐reared males compete for and mate with wild females, order reduce populations...
