“…Herbivores that fed on damaged plant tissue had lower survival rates, reduced individual growth rates, and reduced adult weight or fecundity, or both (Karban and Myers, 1989;Denno et al, 1995). However, the interspecific relationship between insects and pathogens has seldom been studied (Karban et al, 1987;Kanno and Fujita, 2003). The negative interspecific effects between an herbivorous insect and a fungus were first observed in both the spider mite, Tetranychus urticae, and the fungal pathogen, Verticillium dahliae.…”

“…The authors, therefore, were interested in the interspecific relationships between S. furcifera and M. grisea through the host plants, and recently found that the resistance to the rice blast disease caused by M. grisea in the rice is induced by previous infestation of S. furcifera. Furthermore, it was confirmed that the induced resistance in the rice is systemic and is caused by the feeding behavior of S. furcifera (Kanno and Fujita, 2003). In this paper, the results of studies on some other important aspects of this phenomenon are introduced and discussed.…”

The effect of previous rice plant infestation of the white-backed planthopper, Sogatella furcifera, on the incidence of rice blast disease caused by the fungal pathogen, Magnaporthe grisea, was investigated. The fungal pathogen M. grisea was less likely to cause symptoms of leaf blast on rice plants that had been previously infested with S. furcifera than on uninfested plants. This indicates that resistance to M. grisea was induced in rice plants by infestation of S. furcifera. The number of blast lesions per plant decreased with increasing numbers of infesting S. furcifera from 0 to 10 pairs. The active period of induced resistance was maintained for a relatively long time being greater than 15 d. The difference in the incidence of leaf blast between S. furcifera infested and uninfested plants in the booting stage became smaller than that in the tillering stage, although there was a still significant difference in blast incidence between both infested and uninfested plants in booting stage. There was no significant difference in the incidence of leaf blast between damaged plants treated with needling and untreated control plants. This suggests that the simple mechanical effect to the plants caused by stylet insertion (penetration) and subsequent probing with the feeding behavior of S. furcifera was not related to the observed phenomenon. In S. furcifera infested plants, the expression of two genes regarding b-1,3-glucanase, Gns4 and Gns5, was confirmed by RT-PCR analysis. These results show that infestation of S. furcifera apparently induced physiological changes including gene expression that were related to pathogen resistance to M. grisea in rice plants.

Bi-directional interaction between economically important fungal pathogen Botrytis cinerea and aphid Myzus persicea causes serious economic losses to the crop plants resulting in loss of both time and money spend. In bi-direction interaction the fungal pathogen and insect herbivores, can both interact directly with the plant and interact indirectly with each other as they struggle to compete for the resources of the plant. We investigated the bi-directional interaction between the necrotrophic and economically important fungal pathogen Botrytis cinerea Pers Fr (Helotiales Sclerotiniaceae) and the aphid Myzus persicae (Hemiptera Aphididae) on plant host, lettuce Lactuca sativa (Asteraceae: Compositae). Botrytis cinerea on host plant causes a brownish discoloration of the leaf petiole accompanied by the rotting of the leaves, however, presence of aphids on lettuce plants causes' economic damage directly through injury and indirectly through virus transmission, resulting in wilting and head contamination.In this study, it was found that negative interaction between B. cinerea and Myzus persicae was established. The presence of fungal pathogen B. cinerea and Myzus persicae stressed the host lettuce plant, resulting in significant reduction in the rate of photosynthesis and chlorophyll fluorescence, and reduction in the dry shoot and root weight of the lettuce plant. The study established that aphid population growth rate and the number of B. cinerea lesions decreased when both were present on the same host plant.

“…It causes major damage to the rice plants directly by sucking excess plant sap from the phloem and indirectly by transmitting rice plant diseases of economic importance such as Erynia delphacis (Entomophthorales) (Matsui et al, 1998). On the other hand, an effect on the rice also could be induced resistance to rice blast fungus Magnaporthe grisea and Pyricularia grisea, after being infested by S. furcifera (Kanno and Fujita, 2003;Kanno et al, 2005).…”

ABSTRACT. The whitebacked planthopper Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) is one of the most harmful pests of rice. In this study, 18 polymorphic microsatellite markers were developed from S. furcifera genomic libraries using the fast isolation by amplified fragment length polymorphism of sequences containing repeat protocols. Microsatellite polymorphism was investigated using 32 individuals from one natural population. These 18 simple sequence repeat markers showed a number of alleles that ranged from 3 to 15 and had observed and expected heterozygosities that ranged from 0.094 to 0.871 and from 0.148 to 0.924, respectively. The high cross-species transferability of these markers was evaluated in three other planthopper species : Nilaparvata lugens, N. muiri China, and N. bakeri (Muir). These microsatellite markers will provide powerful tools for population genetic and ecological studies of this pest and its related species in the future.
