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). Comparison of the sequence to published Cecdiomyiidae sequences revealed that, despite being undescribed and unnamed, it was previously found in east and south-east Asia to feed on several rust species: Puccinia coronata (Pucciniomycetes: Pucciniales: Pucciniaceae) that develops on Lolium multiflorum (Poaceae), Puccinia sp. on Zea mays (Poaceae), Puccinia arachidis on Arachis hypogaea (Fabaceae) and Puccinia allii on Allium fistulosum (Amaryllidaceae). The new species is described and named here Mycodiplosis puccinivora Jiao, Bu & Kolesik. It occurs in China, Japan, Thailand, Bangladesh and possibly Malaysia and Australia. In Hainan it has four to five generations per year.

Basic Biology

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. All but three species cause variously shaped galls on leaves, while P. mangiferae (Felt) malforms inflorescence and young leaves, and two species feed on fruit – P. frugivora Gagné causing deep lesions and P. fructiculi sp. nov. tunnel-like holes. Of the two fruit-feeding species, P. frugivora is confined to the Philippines while the new species has thus far been recorded only from southern China.

Series Of Experiments

Thirteen ryegrass (Lolium spp.) cultivars and three mixtures of cultivars were evaluated in a series of experiments over four years at two sites in south-eastern Queensland. Stands were sown at 30 kg/ha of viable seed and fertilized with 50 kgN/ha at sowing and after each defoliation. After an establishment period of 6-8 weeks, stands were defoliated every 21 d. Lolium multiflorum cv. Midmar was the highest yielding or equally highest yielding cultivar in three of the four years. Its forage production was better distributed over the full growing season (April- December) and its foliage was less affected by leaf rust (Puccinia coronata Corda) than any other single cultivar. L. rigidum cv. Wimmera was the best cultivar for early season production (before June) and the perennial cultivars (L. perenne cv. Kangaroo Valley and [L. multiflorum x L. perenne] x L. perenne cv. Grasslands Ariki) and cv. Midmar were superior late in the season (September-December). There was little difference in the performance of the other annual (L. multiflorum) cultivars before September. Grasslands Tama gave poorest late season yields. The only mixture that yielded more than its individual components was the Grasslands Tama/Grasslands Ariki combination. Its yield and the distribution of that yield were equivalent to cv. Midmar. Midmar had slightly lower nitrogen levels in the foliage than the other cultivars, but differences were not substantial. The relative ranking of ryegrass cultivars for resistance to rust was Midmar > Kangaroo Valley and Grasslands Ariki > Richmond and Tetila > Grasslands Manawa and Grasslands Paroa > Grasslands Tama, Wimmera, Tetrone and Tetralite.

AbstractA survey of rodents from Luang Prabang Province (Lao PDR) in February 2010 and May 2012 allowed examining lungs of 95 rodents belonging to 7 different genera (Bandicota, Berylmys, Cannomys, Leopoldamys, Maxomys, Mus, Rattus). The helminth Malayometastrongylus diardinematus (Nematoda: Metastrongyloidea) was identified in Rattus tanezumi living in close contact with humans, being the first report after its original description in R. tanezumi from Malaysia. A molecular study using mitochondrial gene cytochrome c oxidase subunit I (COI) of M. diardinematus placed the genus Malayometastrongylus in a separate clade in comparison with Angiostrongylus cantonensis (subgenus Parastrongylus) and other representatives of the genus, both present in rodents of South East Asia.

AbstractA gall midge recently found on Dendrobium orchids in Florida, USA, is identified as Contarinia maculipennis Felt. The identification is based on anatomical similarity to a polyphagous species originally described from Hawaii but which now appears to be from south-east Asia. Contarinia maculipennis is redescribed and compared to Contarinia solani (Rübsaamen) and C. lycopersici Felt, two species with which it has been confused in the literature.

Carya Cathayensis

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. Contarinia caryafloralis is the first gall midge known to feed on a Carya species native to Asia.

Ficus Microcarpa

In November 2009 the gall midge species Horidiplosis ficifolii Harris 2003 was detected in the Czech Republic on leaves of an ornamental fig Ficus microcarpa. The insect is native to South East Asia, where it lives on the genus Ficus. No information is currently available on the prevalence of the pest in the countries of its origin. Imported Ficus plants from China into the Netherlands are sometimes heavily infested with the gall midge. In Europe it is also known from Denmark and the United Kingdom. As Horidiplosis ficifolii is a tropical species, no environmental and social damage is expected.
