Highly reduced genomes of 144-416 kilobases have been described from nutrient-provisioning bacterial symbionts of several insect lineages [1-5]. Some host insects have formed stable associations with pairs of bacterial symbionts that live in specialized cells and provide them with essential nutrients; genomic data from these systems have revealed remarkable levels of metabolic complementarity b...
Insect-borne viral diseases epidemics are influenced by interaction among host plants, viruses, their vectors, and environment. Two species of mealybugs i.e. Planococcus minor Ferrisia virgata known as virus vectors that cause mottle disease on black pepper (Piper nigrum). Research was conducted to determine the main factors affecting spread in field. Study observing 30 productive plants at exp...
Endophytic fungi, Neotyphodium spp. symbiotically infect host grasses, Fescue arundinacea Schreb. and F. pratensis Huds. and Mealybug, Phenococcus solani Ferris attacks some forage plants. To evaluate the role of these fungi to control this pest, four genotypes of F. arundinacea and two genotypes of F. pratensis were used. Plant tillers were split into two sections, one section of which was fre...
