population genetics suggest that multiple invasion processes need to be addressed in the management plan of a plant disease vector.the use of a multidisciplinary approach is becoming increasingly important when developing management strategies that mitigate the economic and biological costs associated with invasive pests. a framework of simulated dispersal is combined with life-history information and analyses of population genetic structure to investigate the invasion dynamics of a plant disease vector, the island sugarcane planthopper (eumetopina flavipes), through an archipelago of significant australian quarantine conce ...201323789032
the effect of host structure on the distribution and abundance of the island sugarcane planthopper, eumetopina flavipes muir, vector of ramu stunt disease of sugarcane.the island sugarcane planthopper, eumetopina flavipes muir, is the only known vector for ramu stunt disease of sugarcane. this study examined the relationship between host plant distribution and abundance, and e. flavipes distribution, abundance and levels of population connectivity in papua new guinea (png), the torres strait (ts) and northern peninsula area (npa) of australia, as a first step in establishing e. flavipes invasion potential through the ts/npa. results show that e. flavipes utili ...200919428738
taxonomy of fulgoraecia melanoleuca (fletcher, 1939), (lepidoptera: epipyropidae) in india, a biological control agent of pyrilla perpusilla (walker) (hemiptera: lophopidae).the parasitic lepidopteran insect, fulgoraecia melanoleuca (fletcher) has been reported as an ectoparasitoid of pyrilla perpusilla (walker) from the indian subcontinent. for the first time, the complete morphology, field biology, egg laying behavior, larval pupal, and adult morphology, including male and female gentialic features, are described and illustrated.201526249916
insect fauna associated with sugarcane plantations in sri lanka.a survey conducted over 13 years (1986-1999) in sugarcane plantations in sri lanka to identify insects associated with sugarcane recorded a total of 103 insect species comprising coleoptera (31 spp.), dictyoptera (2 spp.), diptera (5 spp.), 12 heteroptera (12 spp.), homoptera (18 spp.), hymenoptera (7 spp.), isoptera (3 spp.), lepidoptera (13 spp.), orthoptera (9 spp.), and one species each of thysanoptera, nuroptera and trichoptera. among them were forty-six species of sugarcane pests. in addit ...200315248647
morphology of the indian sugarcane leafhopper, pyrilla perpusilla walker. 19836686572
morphological and histological studies on the neuroendocrine system of the sugarcane leaf hopper, pyrilla perpusilla wlk. (fulgoridae: hemoptera).neuroendocrine system of the sugarcane leaf hopper, pyrilla perpusilla, has been studied by employing pavb and af techniques in situ and on sections. there are four groups of ns cells in the brain, a medial of 14--17 cells, lateral and an antero-ventral of 2 cells each and a latero-ventral of a single cell. the cells are of a and b types: tinctorially the a-cells are further subdivided into a1, a2 and a3 subtypes. suboesophageal and thoracic ganglions have 2 groups of 2 and 3 cells, each of a an ...1977611698
histochemical observations on the mycetomes of pyrilla perpusilla walker.histochemical studies of mycetomes and mycetocytes of pyrilla perpusilla show pas positive material, what can suggest the presence of glycogen. the mycetocytes failed to stain with alcian blue and methyl green pyronin "y" indicating the absence of mucopolysaccharides and rna respectively. the mycetocytes show positive congo red. millon and mercury bromophenophenol blue staining thereby proving that they contain glycoprotein, tyrosine and proteins. positive reaction with sudan black may show the ...1977140837
