The morphology of the third-instar larva of Anastrepha leptozona Hendel is characterized using optical and scanning electron microscopy. The antennomaxillary complex, oral ridges, labium, stomal sensory organ, cephalopharyngeal skeleton, anterior and posterior spiracles and caudal segment are described and illustrated. Mature larvae of A. leptozona present a 'ventral sclerite' below the pharyng...

BACKGROUND Much evolutionary theory predicts that diversity arises via both adaptive radiation (diversification driven by selection against niche-overlap within communities) and divergence of geographically isolated populations. We focus on tropical fruit flies (Blepharoneura, Tephritidae) that reveal unexpected patterns of niche-overlap within local communities. Throughout the Neotropics, mult...

We show that a predator, the tumbling flower beetle Mordellistena convicta (Coleoptera: Mordellidae), has formed host races in response to a host-plant shift and subsequent host-race formation by its prey, the gall-inducing fly Eurosta solidaginis (Diptera: Tephritidae). This fly has formed two host races, one that induces stem galls on the ancestral host plant, Solidago altissima (Compositae),...

A new species of the subfamily Trypetinae, Magnimyiolia perennifascia Singh & David, sp. nov. (Trypetini) is described from India. Two species of subfamily Phytalmiinae, Ectopomyia baculigera Hardy and Ptilona conformis Zia (Acanthonevrini) are recorded for the first time from India. An updated key to Oriental species of Magnimyiolia Shiraki is provided.

An effective lure-and-kill trap is a potentially important instrument in monitoring and controlling oriental fruit flies, Bactrocera dorsalis (Hendel). A number of experiments were performed in an orchard of commercial guava, Psydium guajava L., to determine how fly captures are affected by combining visual and olfactory stimuli, and by the timing of trap deployment relative to host phenology. ...

Wheat germ oil was added to a larval liquid diet for rearing Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to optimize fruit fly quality. Effects of various concentrations of wheat germ oil at 0.04, 0.07, 0.15, 0.30, and 0.66% and their possible mode of action were evaluated. Results suggest that addition of wheat germ oil does not affect pupal weight, larval developmental period, adult e...

Fruit flies are pests of major economic importance in agriculture. Among these pests it is possible to highlight some species of genus Anastrepha, which attack a wide range of fruits, and are widely distributed in the American tropics and subtropics. Researchers seek to identify fruit flies in order to implement management and control programs as well as quarantine restrictions. However, fruit ...

Doryctobracon maculatus Marinho, a new species of Braconidae (Opiinae) collected in the municipalities Piracicaba and São Roque, state Paulo, Brazil, is described illustrated. This placed group with areolate propodeum, but easily distinguished from other this group, members genus by noticeable black to dark-brown spots on head, mesosoma metasoma. was reared larvae Anastrepha pseudoparallela (Di...

The knowledge of host plants, distribution and economic importance Lonchaeidae is scarce in Latin America. We have recovered specimens from most fruit samples containing Tephritidae. compilation information essential to determine the diversity species relationship with their hosts. In addition list records based on early publications, we add unpublished data Lonchaeids plant collected Instituto...
