Genetic Relationship of Fall Armyworm (Spodoptera frugiperda) Populations That Invaded Africa and Asia
The genetic variation of invaded populations was analyzed by comparing the nucleotide sequences of two genes: the nuclear Z-chromosome linked gene triose phosphate isomerase (Tpi) and the mitochondrial gene cytochrome oxidase subunit I (COI) of 27 specimens collected in Africa and Asia.
Citrus diaspidids in Viet Nam: New, and confirmation of previous, records based on morphological and molecular verification of taxa
Milk vetch dwarf virus infection in the Solanaceae and Caricaceae families in Southeast Asia
The results clearly demonstrate MDV infection in Vietnam and Taiwan for the first time and confirm that MDV can infect economically important pepper and tomato.
Discovery of false coconut scale (Aspidiotus rigidus) and three of its primary parasitoids in Việt Nam, and likely species origins
Phylogeography of Diaphorina citri (Hemiptera: Liviidae) and its primary endosymbiont, 'Candidatus Carsonella ruddii': an evolutionary approach to host-endosymbiont interaction.
Evidence is provided for the co-diversification of D. citri and its P-endosymbiont during the migration from South Asia to East and Southeast Asia and it is suggested that the P- endosyMBiont may facilitate investigations into the genealogy and migration history of the host.
Four putative entomopathogenic fungi of armoured scale insects on Citrus in Australia
Each fungal species is characterized and the phylogenetic placement confirmed by molecular analyses of the ITS and 28 s rDNA regions, including location of the fungi within tree canopies.
Emergence of Asian endemic begomoviruses as a pandemic threat
This review highlights crucial information regarding Asia’s four emerging and highly destructive begomoviruses and provides information regarding several less common but still potentially important pathogens of different crops.
Systematics and biology of two species of Microcera associated with armoured scales on citrus in Australia
Field observations suggested that the prevalence of the two fungal parasites in orchards is influenced by host scale densities, climate, and foraging by I. rufoniger workers on honeydew produced by their sternorrhynchan trophobionts, particularly Saissetia oleae.

It is suggested the possibility that the natural distribution of some of the parasitoids of red scale and yellow scale may include East and Southeast Asia, and parts of Australasia, and the possibility of introduced armored scales being recorded on native Rutaceae is suggested.
Mortality on fruit in citrus orchards caused by naturally occurring enemies of red scale Aonidiella aurantii: relation to spatial distribution of patch density and season
This work quantifies the relation of population levels of natural unmanipulated populations of a pest to mortality rates imposed by naturally occurring enemies to cause pest numbers to decline.
