P090-99 Effects of Soil Water Depletion on the Water Relations in Tropical Kudzu

Pereira-Netto AB, Magalhães ACN, Pinto HS*

The effect of reduced soil water content on estomatal conductance, leaflet relative water content (RWC) and temperature were measured in indoor-grown plants of Pueraria phaseoloides. 18% exponential decrease in RWC was related to reduction in soil water content from its maximal retention capacity (100%) to 48%.Pesquisa Agropecuária Brasileira 34: 1151-1157, 1999.

P091-99 Improved histochemical method for choline-containing phospholipid by microwave irradiation on cryosections

Alberto-Rincon MC*, Mello J, Joazeiro PP, Yamada AT

Cryosections and microwave irradiation were used to improve the histochemical method based on the classic hg-diphenylcarbazide reaction to detect a class of phospholipids that contain choline radicals and results were compared with those obtained with conventional thick frozen sections. Microwave irradiation, besides shortening the processing time, improved the resolution and accuracy of choline-containing phospholipid (ccp) localization in tissues.

P092-99 Tabelas de vida de Fannia pusio (Wid.) (Diptera: Fannidae)

Marchiori CH, Prado AP

Several aspects of the population dynamic of F. pusio (Wiedemann) were studied in the laboratory. Adults were collected in Monte Mor, SP, Brazil. Adults were kept in the laboratory and were fed with powdered milk, sugar and bawer yeast. Formulated food for laboratory animals was used as oviposition medium. The reprodudtive rate (Ro) and the rate of natural increase (Rm) were higher at 26oC, with rates of 48,18 and 0,1849, respectively. The greater generation time occurred at 20oC.Anais da Sociedade Entomológica do Brasil 28: 557-563, 1999

P093-99 Megaselia scalaris (Diptera: Phoridae) causing myiasis in Crotalus durissus terrificus (Serpentes: Viperidae) in Brazil

Silva JS, Prado AP, Rodrigues RR, Lopes CRM, Godoy WAC

We decribe a case of myiasis in Crotalus durissus terrificus (Laurent) caused by Megaselia scalaris (Loew). The snake was found in Anhembi, São Paulo, Brazil, with a lesion measuring 25mm in diameter where the larvae of M. scalaris had penetred the ribs. The opportunistic behavior of larvae of M. scalaris is discussed. Journal of Medical Entomology 36: 630-631, 1999. IF= 1.066

P094-99 Massive Orbital Myiasis Infestation

Rocha EM, Yvaroff JC, Silva LMS, Prado AP, Caldato R

Infestation by dipterous fly larvae in ocular and orbital tissues (ophthalmomyiasis) occurs throughout the world, mostly in children and older people and, depending on the genus of the fly, the infestation can be single or multiple larvae. We report a case of orbital myiasis in a man who had more than 100 larvae removed, followed by orbiltal exenteration. Archives of Ophtalmology 117: 1436-1437, 1999. IF= 2.476

P095-99 Aleochara spp. (Coleoptera: Staphylinidae) and pupal parasitoids (Hymenoptera: Pteromalidae) attacking symbovine fly pupae (Diptera: Muscidae, Sarcophagidae and Otitidae) in southeastern Brazil

Almeida MAF, Prado AP*

Samples of house fly, Musca domestica L., stable fly, Stomoxys calcitrans (L.), and Physiphora aenea (F.) puparia were collected weekly at a dairy cattle farm, in Pirassununga (21o 59'S; 47o 21'W and 597.0 km), State of São Paulo, Brazil, between March 1994 and February 1995. Puparia were collected in eigh sites chosen around two manure storage piles and a feeding trough to determine which species comprised the fauna of pupal parasitoids. The seasonal emergence of parasitoids was analyzed for the three species of flie collected. Larvae of Aleochara (Coprochara) notula (Erichson) (Coleoptera: Staphylinidae) were reared and a wasp from family Eucoilidae (Cynipoidea) was found in some puparia (ca. 20) of Sarcophagula sp. (Sarcophagidae). This is the first report of aleocharine larvae attacking puparia of symbovine flies in Brazil.

P096-99 Resistência aos Praguicidas

Prado AP

Resistance is a process of genetic seletion of traits that favor survival of either direct treatment by praguicides or their residues. Resistance occurs by combining natural mutation in a population with seletion by praguicide treatment. The three main categories (biochemical, physiological and behavioral) recognized of resistance are discussed, methods of measuring resistance (bioassays), their documentation, monitoring, and management are considered.

97-99 Ocorrência e sazonalidade de (Omorgus) suberosus (Fabr.) em esterco de aves poedeiras, em Monte Mor, SP

Gianizella SL, Prado AP

Trogidae is a cosmopolitan family whose species have mainly necrophagous habits. They are among the last groups of the sucession of insects that invade carcasses, but they have also been recorded feeding on but guano in caves, locust eggs, fly maggots and unusual itens, such as old carpet and felt-hat. From July 1991 to September 1993 the trogid beetle Omorgus (Omorgus) suberosus (Fabr.) (Coleoptera: Trogidae) were abundantly collected in poultry maure in Monte Mor, SP, with pitfall-traps. The seasonal distribution showed the unimodal pattern with peaks into spring and summer.Anais da Sociedade Entomológica do Brasil 28: 136-138, 1999

P098-99 Batflies parasitic on Phyllostomid Bats in Southeastern Brazil: Parasitism Rates and Host-parasite Relationships

Komeno CA, Linhares AX*

Ectoparasitic batflies were studied on 12 species of phyllostomid bats, by making 35 nightly collections of bats using mist nets at the "Panga" Ecological Reservation near Uberlândia, State of Minas Gerais, Southeastern Brazil, from August 1989 to July 1990. Eleven species of Streblidae and one of Nycteribiidae were collected on 12 species of bats. Prevalence of ectoparasitic flies was lower than those reported by other authors for the New World and may be the result of the lack of caves in the study area, causing bats to roost in less favorable locations, forming smaller colonies. Ecological factors are important in determining differential numbers of parasites occurring on the different sexes, ages and reproductive state of the hosts.

P099-99 Diapause, pupation sites and parasitism of the horn fly, Haematobia irritans, in Southeastern Brazil

Mendes J, Linhares AX*

Pupae of horn fly (Haematobia irritans), were collected from undisturbed cattle dung pats in pastures and adults of the fly were sampled from cattle in São Paulo State, Southeastern Brazil, from April 1993 to July 1994 in order to verify the occurrence of diapause, preference for pupation sites and hymenopteran parasitism. Diapause was verified in 7.7% of pupae sampled from pastures in June and July of 93 and in 9.9 % of those sampled in May, June and July of 94. Approximately 8.3 % of the pupae were parasitized by micro-hymenopterans, mostly by Spalangia nigroaenea and S. cameroni. Pupae mortality was 54.4% and did not change significantly during the year, but the mortality was greater in pupae collected in pastures when compared to those obtained from experimental pats, that lacked natural enemies.Medical and Veterinary Entomology 13: 185–190, 1999.
