The genus Ceratovacuna Zehntner, 1897 (Hemiptera: Aphididae: Hormaphidinae) is reviewed for the first time in China, with the descriptions of five new species, C. angusticorna Qiao sp. n., C. beijingensis Qiao sp. n., C. imperata Qiao sp. n., C. multiglandula Qiao sp. n., C. separata Qiao sp. n. and four new records for China, C. graminum (van der Goot, 1917), C. keduensis Noordam, 1991, C. pan...
This paper uses a methodology based in fuzzy sets theory in order to describe the interaction between the prey, Aphis glycines (Hemiptera: Aphididae) the soybean aphid, and its predator, Orius insidiosus (Hemiptera: Anthocoridae) and to propose a chemical control for soybean aphid. Economic thresholds were already developed for this pest. The model includes biotic (predator) and abiotic (temper...
Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), reached damaging levels in 2003 and 2005 in soybean, Glycine max (L.) Merrill, in most northern U.S. states and Canadian provinces, and it has become one of the most important pests of soybean throughout the North Central region. A common experimental protocol was adopted by participants in six states who provided data from 19 yiel...
As a defense mechanism of the leaves of Rhus javanica (Anacardiaceae) against the aphid Melaphis chinensis (Aphididae) attack, tannic acid is rapidly accumulated and forms galls along the midrib of the leaves resulting in a unique natural medicine Gallae Rhois. Tannic acid was found to inhibit the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) catalyzed by tyrosinase (EC 1.14.18.1) with an ...
Takecallis nigroantennatus Wieczorek sp. nov. (Hemiptera: Aphididae), associated with the cold hardy bamboo variety Fargesia spp. (Bambusoideae), is described and illustrated along a key to species of genus Takecallis. The results mitochondrial COI (DNA barcoding) nuclear elongation factor 1 (EF1α) gene sequences, which confirm genetic difference new taxon from other congeneric species, are pro...
in this study, two aphid species i.e. macrosiphoniella vallesiacae jörg & lample, 1988 on artemisia aucheri and a. sieberi and uroleucon pilosellae (börner, 1933) (hem.: aphididae) on scorzonera sp. were collected which are reported here for the first time from iran. the biometric data of the iranian populations of these two aphid species are given. an identification key to the apterous vivipar...
Abstract Apricot aphid, Myzus mumecola (Matsumura) (Homoptera: Aphididae), was recorded as a new pest of apricot in Hungary the spring 2020. Identification based on morphological and genetical (mitochondrial COI region) characteristics. M. most likely arrived last 2–3 years has quickly become widespread causing significant damage to young trees. Colony development, differences susceptibility be...
