The major fruit fly pests in India belong to the genus Bactrocera: B. cucurbitae (Coquillett), B. dorsalis (Hendel) and B. zonata (Saunders). Other species of Bactrocera, such as B. correcta (Bezzi), B. diversa (Coquillett) and B. latifrons (Hendel), although moderate pests, are localized in their distribution. B. correcta is occasionally reported to dominate B. zonata and B. dorsalis on mango. To date, five or six species of the B. dorsalis complex have been recorded in India, and at least 10 species may occur there, as well as three or four species of the B. zonata complex. B. tau (Walker) and B. scutellaris (Bezzi) have not been recognized even as moderate pests, whereas B. caudata (Walker) is still not fully confirmed in India. The pest status of B. oleae Gmelin has not yet been determined by the olive growers. Dacus ciliatus Loew sometimes becomes a serious pest of squash melons, dominating B. cucurbitae. Amongst the non-dacine species, the capsule fly, Acanthiophilus helianthi (Rossi), and Carpomya vesuviana (Costa) are cause of concern: outbreaks of the capsule fly are sometimes serious on safflower, and C. vesuviana (ber fly) appears to be becoming a major pest of ber. The useful fruit flies include some species that damage local weeds. Procecidochares utilis (Stone), a native of Mexico, is well established on crofton weed. Several other useful fruit fly species, such as Dacus persicus Hendel, Ensina sonchi (Linnaeus), Urophora stylata (Fabricius), and D. sororcula (Wiedemann), attack weeds belonging to Calotropis, Sonchus, Cirsium and Bidens, respectively. Taxonomic, biological and economic information on all these species is given, including data from SEM studies to determine useful but previously unknown taxonomic characters.

Sexual maturation of male Bactrocera correcta (Bezzi) and age-related responses to β-caryophyllene (CP) and methyl eugenol (ME) were examined to identify effective attractants for sexually immature males of the species. Sexual maturation rates (100 × number of cages containing males which attained sexual maturity/total number of cages at a given day) over different ages were 0.0%, 6.7%, and 100.0% for 5-, 6-, and 13-day-old, respectively, and at all the different ages, more males were captured with CP than with ME. The capture rate (the predicted probability by logistic regression) with CP was 29.7% (30.6%) for 5-day-old males, which were still sexually immature, and 52.7% (38.2%) for 6-day-old males, for which the earliest sexual maturation was observed. In contrast, no 5-day-old males responded to ME (the probability was 12.6%), and the capture rate (the probability) of 6-day-old males was merely 0.3% (14.5%), while the rate gradually increased later. The present study revealed that certain males of B. correcta responded to CP prior to sexual maturation but not to ME under the laboratory conditions. These results imply that CP could be an effective attractant used in male annihilation techniques for B. correcta and that ME may not be useful.

A total of 73 species of tephritid flies has been recorded from Florida since the early 1800s. Of these, 7 species are considered to represent occasional waifs or accidental introductions from surrounding regions that are not known to have established populations in Florida; 6 are exotic pests which failed to colonize or were extirpated; and 7 species are represented only by early literature records and are considered dubious for the state. Thus, the tephritid fauna of Florida currently comprises a total of 53 species of which 1 species is precinctive to the state and considered to be endangered.

Semiochemicals are marker or signal chemicals transmitting information between individuals of the same species (pheromones) or different species (allelochemicals). Allelochemicals, depending on their functional roles, comprise kairomones (beneficial to the receiver), synomones (beneficial to both the emitter and receiver), allomones (beneficial to emitter), and apneumones (nonbiological origin). A pheromone of any insect is characterized by its carbon number, functional group, arrangement of double bonds, and ratio between major and minor compounds. With the advent of analytical and electrophysiological techniques, isolation, identification, and synthesis of semiochemicals become easy. Pheromones for a large number of insects belonging to various orders were identified, synthesized, formulated, and used in the field. Monitoring the insects usually for prediction of population, quarantine screening, and dispersal has been done for several species of insects. Mass trapping and mating disruption has been successfully practiced, either alone or in combination with insecticides or biocontrol technologies for effective management of insect pests. Indirectly, these methods reduce insecticide usage and facilitate conservation of natural enemies.

Methyl eugenol, cuelure, and trimedlure are the common parapheromones successfully used for monitoring, mass trapping, and male annihilation. Plant volatiles either alone or in blends are used for mass trapping of several insects, especially coleopteran pests. Apart from lepidopteran, coleopteran, and dipteran insects, pheromones are often used for insects belonging to other orders, especially Homoptera (mealybugs) for monitoring purposes. Kairomones and synomones improve the performance of natural enemies. Antiaggregation pheromones and “autoconfusion” technologies are recent strategies in insect pest management. Development of cost-effective dispensers for mating disruption, semiochemical-based e-noses for monitoring, and creating farmers' awareness are suggested to facilitate the use of semiochemicals in pest management.
