The genus Cystacanthus was established by Anderson (1867: 457) and placed in tribe Ruellieae Dumortier (1829: 23) when published. In fact, it is closely related to Phlogacanthus Nees von Esenbeck (1832: 76, 99) and differs only in the corolla shape and indumentum. Thus, many authors merged Cystacanthus with Phlogacanthus (Benoist 1935, Imlay 1939, Brummit 1992, Mabberley 2008). But it was still...

Objetctive: This experimental study aimed to assess the preference of Gambusia affinis mosquito larvae An.gambiae s.s., Cx. quinquefasciatus and Aedes aegypti. Method: Three were introduced in a glass container with dimension 45cm x 25cmx 25cm. densities used, 90 (30 per species), 120 (40 180 (60 species). Each density experiment was set triplicate monitored after 1, 2, 3, 24 hours. No fish foo...

During routine inspection of a colony of albino western mosquitofish Gambusia affinis, approximately 10 females were discovered to have distended abdominal cavities. Cause for the distention was investigated by examination of tissue sections from four sacrificed individuals, all of which suffered severe ascites. Hermaphroditic gonads were seen in two of the fish.

Ceylon Medical Journal The wasp (Vespa affinis) is common and widely distributed in Sri Lanka. Wasp venom is known to contain factors that release histamine, enzymes, haemolysins, neurotoxins and vasodilators [1]. Case reports with severe multi-organ dysfunction after wasp stings are few in literature. We report two patients who developed severe multi-organ dysfunction following multiple wasp b...

We isolated nine microsatellite loci from the Neotropical understorey tree Miconia affinis (Melastomataceae) and optimized them for research on gene flow and genetic structure. Loci screened in 43 individuals from a 2.26-km(2) region were shown to be unlinked and polymorphic, with 5 to 14 alleles per locus and observed heterozygosity ranging from 0.394 to 0.810.

The main focus of this research is to ascertain the X-ray diffraction (XRD) pattern, Fourier transform infrared (FTIR) spectroscopic and surface morphology a hornet (Vespa affinis) nest. optical microscopic (OM) analysis demonstrated that nest presented an irregular formation partition materials. This was confirmed via scanning electron microscopy (SEM), which revealed presence unique form with...

The genus Xiruana Brescovit, 1997 is currently composed of four South American species: X. gracilipes (Keyserling) from Brazil, Bolivia and Argentina, X. affinis (Mello-Leitão) from Brazil, X. hirsuta (Mello-Leitão) from Venezuela, Brazil, Paraguay, Argentina and Uruguay, and X. tetraseta (Mello-Leitão) from Venezuela, Brazil and Paraguay. Of these, the last three are redescribed in this paper,...

The species Ixodes aragaoi Fonseca was described as Ixodes ricinus aragaoi, and later placed in synonymy with Ixodes affinis. However, this synonymy was rejected and the subspecies was elevated to species, and named as I. aragaoi. Some researchers did not consider the validity of I. aragaoi and maintained the synonymy proposed until 1998 when I. aragaoi was revalidated, and it was suggested tha...
