The Heteroptera have holocentric chromosomes with kinetic activity restricted to the end of chromosomes.The first meiotic division is reductional for the autosomes and equational for the sexual. Only a few species of this suborder have been analyzed. In this study, we observed the morphologies of the testes of the Heteroptera species Belostoma anurum (Herrich-Schäffer, 1948), Belostoma micantul...

The flea beetle Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is the main pest of the bioenergy crop Jatropha curcas L. (Euphorbiaceae) in Burkina Faso and several other West African countries. Adults severely defoliate plants, resulting in seedling mortality, poor growth, and low yields. To study the population dynamics of the pest in the Sissili Province of Burkina Faso, 12 sites wer...

Penelitian ini bertujuan untuk menentukan aktifitas penghambatan kerja enzim ?-glucosidase oleh ekstrak air dan etanol dari daun, batang akar kayu kuning ( Arcangelisia flava ) secara in vitro. Aktifitas a-glukosidase diukur pada panjang gelombang 400 nm berdasarkan jumlah p-nitrofenol yang dihasilkan. Daya hambat dilihat nilai IC 50 . Dari sebesar 195,161; 138,9881 48,68632 mg/mL 365,8793; 123...

OBJECTIVES In this study, we demonstrated that TBEV-infected ticks have been distributed in the ROK, combined with our previous results. These results suggest that TBEV may exist in the ROK, and H. longicornis, H. flava, and I. nipponensis may be potential vectors of TBEV. In addition, these results emphasize the need for further epidemiological research of TBEV. METHODS We examined for the p...

Sugarcane (Saccharum spp.) in Louisiana is colonized by two aphid species, the sugarcane aphid, Melanaphis sacchari (Zehntner), and the yellow sugarcane aphid, Sipha flava (Forbes) (Hemiptera: Aphididae). The main problem associated with M. sacchari is transmission of sugarcane yellow leaf virus, a casual agent of yellow leaf disease whose absence has been added to certification standards for m...

This species superficially resembles Scaptodrosophila paratriangulata (Gupta, 1971) in having cross striped abdominal tergites, apically rounded wing, ocellar triangle brownish black, heel of the genital arch not pointed and the row of teeth of surstylus not convexed. However, this species distinctly differs from S. paratriangulata in having dark coloration, basal apodeme of aedeagus (usually l...

Kalimantan is an island with abundance of kayu Kuning (yellow-fruited moonseed) . Kayu kuning used for three different plant species, namely Arcangelisia flava (L.) Merr., Fibraurea tinctoria Lour., and Coscinium fenestratum (Gaertn.) Colebr. Therefore, it creates confusion may cause improper use. It has properties such as anti-diabetic, antiplasmodial, antidiarrheal, hepatitis, antidote. The s...

This publication provides the first comprehensive DNA barcode data set for the Neuropterida of Central Europe, including 80 of the 102 species (78%) recorded from Bavaria (Germany) and three other species from nearby regions (Austria, France and the UK). Although the 286 specimens analyzed had a heterogeneous conservation history (60% dried; 30% in 80% EtOH; 10% fresh specimens in 95% EtOH), 23...
