A review of the gall midges (Diptera: Cecidomyiidae) of Indonesia: taxonomy, biology and adult key to genera.

Forty-seven species in 25 genera of gall midges (Diptera: Cecidomyiidae: Cecidomyiinae) known from Indonesia are reviewed. Available historic types were examined, and taxa are revised. Leefmansiella Kolesik Gagné gen.

A new genus and species of gall midge (Diptera: Cecidomyiidae) inducing leaf galls on Peking lilac, Syringa reticulata subsp. pekinensis (Oleaceae), in China.

Larvae of a previously unknown species of gall midge were found causing large numbers of pustulate leaf galls on Peking lilac, Syringa reticulata subsp. pekinensis (Oleaceae), in parklands and street greenery in Beijing, China. Heavily galled leaves become senescent and fall off prematurely.

New Mycodiplosis gall midge (Diptera: Cecidomyiidae) feeding on fungal rusts (Fungi: Pucciniomycetes) that are pathogenic on cultured plants.

Larvae of a gall midge were found feeding on the fungal rust Maravalia pterocarpi (Pucciniomycetes: Pucciniales: Chaconiaceae) infesting the economically important sua tree Dalbergia tonkinensis (Fabaceae) on Hainan Island, China. The adults, pupae and larvae were collected, their morphology was studied and a segment of the Cytochrome Oxidase unit I (COI) mitochondrial gene was sequenced. The gall midge proved to be a species new to science that belongs to the genus Mycodiplosis (Diptera: Cecdiomyiidae).

Redescription of Mitodiplosis graminis (Diptera: Cecidomyiidae), a gall midge inhibiting the flowering of pyp grass Ehrharta villosa (Poaceae) in South Africa.

Mitodiplosis graminis Kieffer, the only species of the genus Mitodiplosis (Diptera: Cecidomyiidae), was described in 1914 as the causative agent of an unspecified gall on pyp grass Ehrharta villosa (Poaceae) in South Africa. The type specimens are presumed lost. We reared all developmental stages of the gall midge, redescribe here the male and female, and describe for the first time the gall, egg, larva and the pupa.

Discovery of BNC375, a Potent, Selective, and Orally Available Type I Positive Allosteric Modulator of α7 nAChRs.

Positive allosteric modulators (PAMs) of α7 nAChRs can have different properties with respect to their effects on channel kinetics. Type I PAMs amplify peak channel response to acetylcholine but do not appear to influence channel desensitization kinetics, whereas Type II PAMs both increase channel response and delay receptor desensitization. Both Type I and Type II PAMs are reported in literature, but there are limited reports describing their structure-kinetic profile relationships.

A new species of Contarinia (Diptera: Cecidomyiidae) damaging inflorescence of Carya cathayensis (Juglandaceae) in China.

Chinese hickory, Carya cathayensis Sargent (Juglandaceae), is a tree naturally occurring and industrially grown in China for the nuts that are valued for their taste and nutrient content. Larvae of a previously unknown species of gall midge were found feeding on male and female inflorescences of Carya cathayensis in Zhejiang and Anhui Provinces in eastern China, reducing pollination and fruit development, and causing substantial damage to the nut industry. The new species is named Contarinia caryafloralis Jiao, Bu Kolesik, its morphology is described, the basic biology is given, and the Cytochrome Oxidase subunit I (COI) mitochondrial gene segment is sequenced.

A new species of Procontarinia (Diptera: Cecidomyiidae) damaging fruit of mango, Mangifera indica (Anacardiaceae), in China.

Larvae of a previously unknown species of gall midge were found feeding on young fruit of mango, Mangifera indica (Anacardiaceae), in Guangxi Autonomous Region in southern China, causing severe damage to the crop. The new species is named Procontarinia fructiculi Jiao, Wang, Bu Kolesik, its morphology is described, the basic biology is given, and the Cytochrome Oxidase subunit I (COI) mitochondrial gene segment is sequenced and compared to other congeners. Procontarinia contains now 16 described species, each feeding on mango.

Revision of early taxa of Australian gall midges (Diptera: Cecidomyiidae).

Australian Cecidomyiidae described by Schiner (1868), Skuse (1888, 1890), Koebele (1893), Felt (1915), Edwards (1916) and Rübsaamen (1916), totalling 111 species and three subgenera, are revised. Chastomera Skuse, 1888 is confirmed to be a junior synonym of Haplusia Karsch, 1878 and Gonioclema Skuse, 1888 and Necrophlebia Skuse, 1888 are declared nomina dubia. Twenty-two species are placed to genus, an additional four species are placed to supertribe or subfamily, all of them redescribed.

Structure-activity relationship studies of SEN12333 analogues: determination of the optimal requirements for binding affinities at α7 nAChRs through incorporation of known structural motifs.

Alpha7 nicotinic acetylcholine receptors (nAChRs) have implications in the regulation of cognitive processes such as memory and attention and have been identified as a promising therapeutic target for the treatment of the cognitive deficits associated with schizophrenia and Alzheimer's disease (AD). Structure affinity relationship studies of the previously described α7 agonist SEN12333 (8), have resulted in the identification of compound 45, a potent and selective agonist of the α7 nAChR with enhanced affinity and improved physicochemical properties over the parent compound (SEN12333, 8).

The mechanism of boron tolerance for maintenance of root growth in barley (Hordeum vulgare L.).

Cultivar differences in root elongation under B toxic conditions were observed in barley (Hordeum vulgare L.). A significant increase in the length and width of the root meristematic zone (RMZ) was observed in Sahara 3771 (B tolerant) when it was grown under excessive B concentration, compared to when grown at adequate B supply.
