The identity of Pentalonia nigronervosa Coquerel and P. caladii van der Goot (Hemiptera: Aphididae) based on molecular and morphometric analysis
نویسنده
چکیده
Pentalonia nigronervosa (sensu Hardy 1931) samples from banana and from Zingiberaceae and Araceae species exhibit fixed differences in DNA sequence in mitochondrial cytochrome oxidase subunit 1 (“DNA barcode”) and in the nuclear gene elongation factor 1α, and have morphometric differences, including non-overlapping ranges in the length of the distal rostral segment. It is thus proposed that the name P. nigronervosa Coquerel be restricted to banana-feeding ‘nigronervosa’ specimens, and that the name Pentalonia caladii van der Goot be restored to full species status for specimens typically feeding on Zingiberaceae and Araceae.

A Comparison of Fitness Characters of Two Host Plant-Based Congeneric Species of the Banana Aphid, Pentalonia Nigronervosa and P. Caladii
Aphids and other phytophagous insects often show intra-specific variations in relation to host plant utilization. In several instances, intra-species variations lead to host-plant specialization. These are considered to be important source of speciation. In a recent study ( Foottit RG et al. 2010 . Zootaxa 2358: 25–38) two forms of the banana aphid, Pentalonia nigronervosa f typica Coquerel (He...
متن کاملLocalization, Concentration, and Transmission Efficiency of Banana bunchy top virus in Four Asexual Lineages of Pentalonia aphids
Banana bunchy top virus (BBTV) is the most destructive pathogenic virus of banana plants worldwide. The virus is transmitted in a circulative non-propagative manner by the banana aphid, Pentalonia nigronervosa Coquerel. In this work, we examined the localization, accumulation, and transmission efficiency of BBTV in four laboratory-established lineages of Pentalonia aphids derived from four diff...

The banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae), infests banana (Musa spp.) worldwide. Pentalonia nigronervosa is the vector of Banana bunchy top virus (family Nanoviridae, genus Babuvirus) the etiological agent of Banana bunchy top disease (BBTD). BBTD is currently the most serious problem affecting banana in Hawaii. Despite the importance of this vector species, litt...

The banana aphid, Pentalonia nigronervosa Coquerel, is present worldwide where banana (Musa spp.) is grown. It is the vector of Banana bunchy top virus (Nanoviridae, Babuvirus), the etiological agent of banana bunchy top disease, currently the most important constraint for banana producers in Hawaii. P. nigronervosa is not well studied, and effects of temperature on its growth and reproduction ...

Most parasitoids of aphids are small wasps belonging to the families Braconidae or Aphelinidae. However, some dipteran parasitoids are also known to use aphids as hosts. We describe and give life-history information on a new species of aphid parasitoid, Endaphis fugitiva Gagné and Muratori, found to parasitize the banana aphid, Pentalonia nigronervosa Coquerel, the vector of banana bunchy top v...
