Fruit flies (Tephritidae) and lance flies (Lonchaeidae) (Diptera) include pests of highest economic importance to horticulture around the world, because various species damage high value fruit crops, These Tephritoidea are the reason for quarantine barriers among many countries, limiting the commerce of fresh fruits and vegetables. Knowledge of frugivorous tephritoid species richness and their interactions with the host plants are extremely important to Integrated Pest Management. This paper presents the interactions of 15 species of Anastrepha Schiner, Ceratitis capitata (Wiedemann) (Tephritidae), and eight species of Neosilba McAlpine (Lonchaeidae) with 40 host fruit species. We discovered that Pouteria glomerata (Miquel) Radlkofer (Sapotaceae) is the host fruit of Anastrepha undosa Stone. A. zernyi Lima was associated with fruit of Anacardium othonianum Rizzini (Anacardiaceae). This is the first record of A. zernyi from the State of Mato Grosso do Sul, and of A. hastata Stone from Central Brazil, A. sorocula Zucchi and A. zenildae Zucchi were the tephritids that infested the highest number of host fruits, A. alveatoides Blanchard, A. distincta Greene, A. macrura Hendel, A. rheediae Stone and A. undosa Stone were recovered from only one species of host, and all of these associations are new records. Also established for the first time are the associations among eight species of Neosilba with 38 host species. N. zadolicha McAlpine and Steyskal, N. pendula (Bezzi), N. glaberrima (Wiedemann) and N. inesperata Strikis and Prado were the most polyphagous Lonchaeidae.

ABSTRACT. Diversity of Odonata (Insecta) in lotic systems from Serra da Bodoquena, Mato Grosso do Sul State, Brazil. A systematic survey was carried out in four lotic systems from Serra da Bodoquena, the largest natural forests of the State, from August 2007 to November 2008. 548 specimens belonging to 33 species, distributed in 5 families were sampled. Libellulidae was dominant, with 13 species, followed by Gomphidae, Coenagrionidae, Protoneuridae and Calopterygidae.

ABSTRACT. This paper presents a five years survey of endoparasitoids obtained from the larvae of frugivorous Tephritidae and Lonchaeidae flies. The insects were reared from cultivated and wild fruits collected in areas of the cerrado in the State of Mato Grosso do Sul, Brazil. The flies obtained from 14 host fruit species were eight Anastrepha species, Ceratitis capitata (Wiedemann, 1824) (Tephritidae); Dasiops sp. and Neosilba spp. (Lonchaeidae). Eleven parasitoid species were collected: Braconidae -Asobara anastrephae (Muesebek, 1958), Doryctobracon areolatus (Szépligeti,

Antlions larvae are sit-and-wait predators that capture arthropod prey in conical sand pits. The aim of this paper were to determine the effect of different natural diets [leaf-cutting ants (Atta spp.), fruit fly larvae (Anastrepha spp. and Ceratitis capitata) and mixed diet (Atta spp. plus fruit fly larvae)] on the development of larvae and pupae of M. brasiliensis (Navás, 1914) and to estimate the number and size of prey caught in each instar and on each kind of diet. The average duration (days) of the second and third instars of M. brasiliensis was longer when larvae of antlion were fed with leaf-cutting ants. The diets did not affect the duration of the pupal stage nor the pupae size. The different diets did not affect the mean width of head capsule (mm), the mean weight (mg) or the mean body size (mm) in the different instars of M. brasiliensis. In the second and third instars, the larvae of M. brasiliensis fed with leaf-cutting ants consumed more prey than larvae kept on other diets. Adults whose larvae were fed fruit fly larvae were larger than adults on other diets. Although Myrmeleontidae are few studied in Brazil, these results contribute to knowledge of M. brasiliensis biology, but also suggest the need of studies about the development of larvae and pupae in natural environments.

ABSTRACT. Fruit flies (Diptera, Tephritidae) and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil. Information on frugivorous flies in cultivated or wild host plants and their parasitoids in the Cerrado-Pantanal ecotone in Aquidauana, Mato Grosso do Sul is presented and discussed. Fruit fly samples were collected weekly in specific fruit trees, and McPhail ® traps were installed in the same trees for a period of two years. The fruit flies infested ripe and unripe fruits of Averrhoa carambola L., Schoepfia sp., Psidium guajava L. and Pouteria torta (Mart.) Radlk and mature fruits of Anacardium occidentale L. and Inga laurina (Sw.) Willd. Nineteen fruit fly species were obtained with the combination of sampling methods (collecting fruits and trapping), nine of them obtained with both methods, five found only in fruits and five only in traps. This is the first record of Anastrepha striata Schiner in a species of Sapotaceae, as well as for A. castanea Norrbom and A. daciformes Bezzi in Schoepfia sp. (Olacaceae), and for A. distincta Greene in fruits of P. guajava in the state of Mato Grosso do Sul. Fruit collections simultaneously associated with capture of fruit flies by McPhail traps in the same host plants are essential to understand the diversity of fruit flies and their relationship with hosts and parasitoids. Species of Braconidae and Pteromalidae were recovered, where Doryctobracon areolatus (Szépligeti) was the most abundant parasitoid in larvae of tephritids infesting both cultivated and wild host fruits.
