The leaf miner, Liriomyza huidobrensis (Diptera: Agromyzidae) is a polyphagous fly, which infests wide range of vegetables and ornamental plants. However, scant knowledge exists the biology ecology pest in Western Cape province South Africa, both are essential components developing an effective management programme. Several aspects its were studied two potato [Solanum tuberosum L. (Solanales: S...

Liriomyza huidobrensis (Blanchard) is a highly destructive invasive leafminer pest currently causing extensive damage to vegetable and horticultural crops around the world. Liriomyza langei Frick is a leafminer pest native to California that cannot currently be morphologically distinguished from L. huidobrensis. We used a DNA-barcoding approach, a published PCR-RFLP method, and a new multiplex ...

Diglyphus isaea Walker (Hymenoptera: Eulophidae) is an important ectoparasitic wasp of many leaf miners. Ability of D. isaea to find hosts placed in artificial mines and for its larvae to pupate when the larva is not in a mine was studied. Artificial mines consisted of slits cut in index card sandwiched between two cover slips. Almost 80% of the neonate larvae of D. isaea located host larvae in...

DNA barcoding involves the sequencing of a single gene region from all species to provide a means for identifying all of life. Although appealing to many scientists, this idea has caused considerable controversy among systematists. We applied a DNA barcoding approach to outbreak populations of invasive Liriomyza spp. leafminer pests in the Philippines to explore the use of barcoding in a relati...

The wheat sheath miner, Cerodontha australis, is widespread and abundant in New Zealand also occurs eastern Australia. Adult larval C. australis feed on cereals grasses, including the economically important perennial ryegrass, Lolium perenne. There little literature about much of early work may relate to other species due its initial misidentification. Morphology-based identification can be cha...

Production of asparagus (Asparagus offi cinalis L.) is globally constrained by the “early decline” syndrome. The primary causal agents of early decline include Fusarium proliferatum (Matsushima) Nirenberg, F. oxysporum Wollenw. f. sp. asparagi S.I. Cohen, and F. subglutinans Wollenw. & Reinking. These pathogens together contribute to Fusarium crown and root rot (FCRR). Damage to asparagus stems...
