Hornets are large, predatory wasps that have the potential to alter biotic communities and harm honey bee colonies once established in non-native locations. Mated, diapausing females (gynes) can easily be transported new habitats, where their behavioral flexibility allows them found using local food nest materials. Of 22 species genus Vespa , five now naturalized far from endemic populations an...

Technological and analytical advances to study evolutionary biology, ecology, conservation of the Southern River Terrapin (Batagur affinis ssp.) are realised through molecular approaches, including DNA barcoding. We evaluated use COI barcodes in Malaysia’s population better understand species’ genetic divergence other characteristics. 26 sequences, four from field specimens Terrapins obtained B...

A critical review of the family Veliidae (Hemiptera: Heteroptera: Gerromorpha) in Romania is provided. In total, two genera and eight species (Microvelia Westwood, 1834-3 species, Velia Latreille, 1804-5 species) are known from the country. Microvelia buenoi Drake, 1920 and Velia serbica Tamanini, 1951 are recorded for the first time from Romania. The occurrence of V. affinis filippii Tamanini,...

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.

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.
