New records of Muscidae (Diptera) in Campo Grande, MS, Brazil

Synanthropic flies outstanding beside other flies due their relative abundance close to domestic animals and human population, to which they are able to cause myiasis or transmit pathogenic agents. As they're necrophagous they act as corpse decomposers and are useful in the forensic entomology in the post mortem interval determination. This study aimed to know flies diversity and abundance in Campo Grande, State of Mato Grosso do Sul. Captures were made weekly, utilizing three traps baited with decaying fish meat, from June of 2008 to May of 2009 in a remainder ciliary forest of the Embrapa's Cattle Beef Experimental Farm. The dipterans families that were considered and respectively number of collected specimens were: Calliphoridae (105,334); Muscidae (27,999); Sarcophagidae (21,083); Fanniidae (17,759) and Mesembrinellidae (305), totalizing 172,480 dipterous. To the local known species some Muscidae were increased as follows: Neomuscina atincticosta, Pseudoptilolepis elbida, Polietina orbitalis, Polietina flavithorax, Scutellomusca scutellaris, Graphomya analis and Morellia couriae

OCCURRENCE OF PHYTOPHAGOUS SCARABAEIDAE (INSECTA: COLEOPTERA) LARVAE IN DIFFERENT SUCCESSION CROP SYSTEMS OCORRÊNCIA DE LARVAS DE SCARABAEIDAE FITÓFAGOS (INSECTA: COLEOPTERA) EM DIFERENTES SISTEMAS DE SUCESSÃO DE CULTURAS

Information about Scarabaeidae phytophagous are still rare for the Center-West Region of Brazil. Thus, in the experimental area of the Universidade Estadual do Mato Grosso do Sul, in Aquidauana, Mato Grosso do Sul State, Brazil, the succession of soybean, maize, and forage turnip was sowed from February 2004 to October 2005, when the larvae population dynamics was evaluated. From October 2006 to May 2008, nine succession systems were sowed, the larval density evaluated, and the identification of the current species was carried out. When the larvae were sampled for soybean, in January 2005 and 2006, the highest densities were found in the field (3.44 larvae m-2 and 4.19 larvae m-2, respectively). The forage turnip, sampled in October 2004 and 2005, showed the lowest densities (0.03 larvae m-2 and 0.02 larvae m-2, respectively). In the crop succession systems, the following species were found: Liogenys fuscus Blanchard (highest amount), Liogenys bidenticeps Moser, Anomala testaceipennis Blanchard, Paranomala inconstans (Burmeister), Geniates borelli Camerano, Cyclocephala forsteri Endrodi, Cyclocephala verticalis Burmeister, and Phyllophaga sp. For the succession systems with maize sowed at the traditional season, the highest larval densities were found, specially favoring the development of L. fuscus, while the succession systems with soybean, maize, and under fallow, and soybean, crotalaria, and forage turnip, as well as the three systems with cotton-plant, did not favor it.&lt;br /&gt;&lt;br /&gt;KEY-WORDS: Zea mays; Glycine max; Raphanus sativus; soil pests; larvae density.<br>Informações sobre Scarabaeidae fitófagos são ainda escassas para a região Centro-Oeste do Brasil. Por esta razão, na área experimental da Universidade Estadual do Mato Grosso do Sul, em Aquidauana (MS), foi semeada, de fevereiro de 2004 a outubro de 2005, a sucessão de culturas soja, milho e nabo forrageiro, onde se avaliou a dinâmica da densidade larval. De outubro de 2006 a maio de 2008, foram realizadas semeaduras de nove sistemas de sucessão de culturas, sendo avaliadas as densidades larvais e identificadas as espécies ocorrentes. Quando se amostraram as larvas na cultura da soja, em janeiro de 2005 e 2006, encontraram-se as maiores densidades (3,44 larvas m-2 e 4,19 larvas m-2, respectivamente), no campo. O nabo forrageiro, amostrado em outubro de 2004 e 2005, apresentou as menores densidades (0,03 larvas m-2 e 0,02 larvas m-2, respectivamente). Nos sistemas de sucessão de culturas, as espécies encontradas foram Liogenys fuscus Blanchard, Liogenys bidenticeps Moser, Anomala testaceipennis Blanchard, Paranomala inconstans (Burmeister), Geniates borelli Camerano, Cyclocephala forsteri Endrodi, Cyclocephala verticalis Burmeister e Phyllophaga sp, sendo que  L. fuscus foi coletada em maior quantidade. Para os sistemas de sucessão que possuem o milho semeado na safra, foram encontradas as maiores densidades larvais, indicando que esta cultura favorece o desenvolvimento, principalmente, de L. fuscus, enquanto os sistemas de sucessão com soja, milho e pousio, e soja, crotalária e nabo forrageiro, bem como os três sistemas com o algodoeiro, lhe são desfavoráveis.&lt;br /&gt;&lt;br /&gt;PALAVRAS-CHAVE: Zea mays; Glycine max; Raphanus sativus; pragas do solo; densidade de larvas

OCORRÊNCIA DE CYCLOCEPHALA MELANOCEPHALA (COLEOPTERA: SCARABAEIDAE) EM SERINGUEIRA

Os adultos de Cyclocephala Dejean, 1821 são conhecidos principalmente por sua associação com flores de várias espécies vegetais. Em uma área comercial de seringueira em Inocência, MS, foram observados adultos de C. melanocephala (Fabr., 1775) causando danos. Em plantas de seringueira com 1,0 a 1,20 m de altura, foram quantificados no ponteiro e ápice de trinta plantas, entre 40 a 120 adultos em cada planta, sendo que em sua maioria já estavam mortos e unidos uns aos outros. Os ponteiros e ápices das plantas não apresentavam folhas ou brotações, pois haviam sido consumidos. Devido à produção de látex por essa espécie vegetal, os insetos ao se alimentarem da planta proporcionaram o extravasamento do látex, o que levou ao aprisionamento dos insetos na própria planta. Registra-se pela primeira vez a ocorrência de C. melanocephala se alimentando e causando danos em folhas de seringueira

Fruit flies (Diptera, Tephritidae) and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil

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
