Ueber die hautdruesen von Apiomerus nigrilobus Stal, 1872 (Reduviidae, Apiomerinae)

Die ersten beiden Beinpaare und die Unterseite des Abdomens von Apiomerus nigritobus sind dicht mit Borsten besetzt, zwischen denen sich ein klebriges Sekret befindet. Das Sekret hilft den Tieren, ihre Beute zu ueberwaeltigen. Es wird in Druesenzellen hergestellt, die unter der Hypodermis als Einzelzellen oder als kleine Zellgruppen liegen. Die Druesenzelle besitzt homogenes Protoplasma und einen zentral gelegenen Kern. Der Ausleitungsapparat besteht aus einem langen, in der Zelle stark gewunden verlaufenden Cuticularroehrchen von etwa 0,2μ. Dicke, das von besonderen Zellen der Hypodermis gebildet wird. Die Oeffnung auf der Cuticula besitzt keine Hilfsapparate. Ausstoss und Transport des Sekrets beruhen auf dem Sekretdruck der Druesenzelle.

A new species of Pseudoxenus Saunders, 1872, and a new record of Myrmecolax Incautus Oliveira & Kogan, 1959: (Strepsiptera, Insecta)

Os A. A. descrevem Pseudoxenus inclusus sp. n., baseados em uma fêmea e centenas de triungulinideos, encontrados parasitando Ammophila sp., proveniente de Corrego do Itá, Espírito Santo, Brasil. O encontro de um outro exemplar de Myrmecolax incautus Oliveira & Kogan, 1959, permitiu aos AA. complementar a descrição desta espécie, cujo holótipo está muito danificado.

Rhodnius stali n. sp., afim de Rhodnius pictipers Stal, 1872 (Hemiptera, Reduviidae, Triatominae)

Rhdnius stali n. sp. was described based on specimens deposited in the Herman Lent Collection of Entomological Collection of Oswaldo Cruz Institute, until now identified as Rhodnius pictipes Stal, 1872 and compared with specimens of R. pictipes proceeding from state of Amazonas and Pará, Brazil. R. stali is related to R. pictipes though distinguished by the total length, 15 to 17 mm male and 16,5 to 19 mm female, the anteocular region 2,5 times larger than postocular region and by the shape of phallic strictures known as: phallosoma, struts, gonopore process and endosoma process.

Biologia do Rhodnius pictipes Stal, 1872 em condições de laboratório (Hemiptera, Reduviidae, Triatominae)

Rhodnius pictipes Stal, 1872 is a silvatic species with a widespread distribution in South America, found in nine Brazilian states, naturally infected by Trypanosoma cruzi and T. rangeli. The individual rearing of this species under laboratory conditions, allowed the following biological aspects to be observed: incubation time, search for first meal after eclosion or moult, time - lapse between presentation of the blood meal and the beginning of feeding, duration of blood meal, time and place of defecation, number of blood meals, duration of each instar and adult longevity, and time required from egg to adult.
