“…On tomato plants, oviposition of T. urticae was decreased by 20-25% in the simultaneous presence of the fungus Fusarium oxysporum Schltdl. (Jongebloed et al, 1992). However, reduced oviposition of the spider mites was not necessarily due to the fungus because an effect of similar quality and magnitude was triggered by water stress (Jongebloed et al, 1992).…”

“…(Jongebloed et al, 1992). However, reduced oviposition of the spider mites was not necessarily due to the fungus because an effect of similar quality and magnitude was triggered by water stress (Jongebloed et al, 1992). Pathogens as well as herbivore attacks may influence a plethora of plant quality parameters such as the qualitative and quantitative content of nutrients, primary and secondary metabolites, plant biomass, morphological features, water content, etc.…”

“…and their relation to each other (van Dam et al, 2003). A clear characterization of the underlying mechanisms of plant-mediated interactions between the pathogens and the mites was not undertaken in any of the above-mentioned studies (Karban et al, 1987;Ajlan and Potter, 1991;Apriyanto and Potter, 1990;Jongebloed et al, 1992). Stout et al (2006) thoroughly reviewed the variability of plantmediated pathogen-herbivore interactions, but did not provide explanations for the lack of a common trend in the above cited studies, which appear to be fairly similar in their experimental setups.…”

“…Proximately, the observed changes in spider mite performance were ascribed to induced direct resistance (e.g. Karban et al, 1987) via an increase in plant secondary compounds (Tomczyk 1999(Tomczyk , 2002(Tomczyk , 2006Tomczyk and Kielkiewicz, 2000), water stress (Jongebloed et al, 1992), change in plant primary nutrient composition (Hoffmann et al, 2009;Katayama et al, 2010), or combinations thereof (Nishida et al, 2010). Although all studies were performed with the same species of aboveground herbivore, no predictions can be made regarding the outcome of the interac-tion or possible mechanisms to be triggered.…”

“…It is entirely possible that some of these fungi may also affect the feeding of insects and that our inoculations caused changes in the abundance of species, such as S. elegantulum and F. oxysporum, which lead to effects on insects. While effects of the former fungus on insect herbivores have yet to be studied, a pathogenic strain of F. oxysporum is known to reduce mite oviposition on tomato (Jongebloed et al 1992).…”

Differential effects of foliar endophytic fungi on insect herbivores attacking a herbaceous plant

et al. 2011

Foliar endophytic fungi appear to be ubiquitous in nature, occurring in a very wide range of herbaceous plants. However, their ecological role within forbs is very poorly known and interactions with foliar-feeding insects virtually unexplored. In this study, leaves of Cirsium arvense were infected with different combinations of endophyte fungi that had been previously isolated from this plant species. Two months later, leaf material was fed to larvae of a generalist insect, Mamestra brassicae, and adults of a specialist feeder, Cassida rubiginosa. Endophytes had different effects on the two insects; one species, Chaetomium cochliodes, reduced growth of M. brassicae but increased feeding by C. rubiginosa. Another species, Cladosporium cladosporioides, increased beetle feeding also, but had no effect on M. brassicae. Interactions were also seen between fungal species and dual infection with C. cladosporioides and Trichoderma viride greatly reduced beetle feeding. It is concluded that endophytes have significant effects on foliar feeding insects that differ with degree of specialism of the herbivore. We suggest that these effects are due to chemical changes in the host, brought about by fungal infection. These fungi have received remarkably little attention in the study of insect-plant interactions and yet could be important determinants of insect growth and even population dynamics.

Neoseiulus cucumeris (Oudemans) (Acari: Phytoseiidae) is one of the most widely used and important biological control agents for thrips and other small pests worldwide. In the present study, we cloned two cDNAs of vitellogenins (Vgs, NcVg1 and NcVg2) and analyzed the effect of food source on the expression of both Vgs and fecundity in female adults. NcVgs showed higher sequence similarity to Vgs from Parasitiformes. Both neighbor-joining and maximum likelihood methods for phylogenetic analysis of NcVgs yielded similar topologies and showed that the Parasitiformes except Haemaphysalis longicornis segregated into a single clade that was separated into two subclades including one of both Vgs from N. cucumeris. Both transcripts, NcVg1 and NcVg2 revealed similar trends during developmental periods and reached the maximum level at the pre-oviposition period. When fed with different food sources, both NcVg1 and NcVg2 of female adults demonstrated a significant difference (P < 0.05) during the pre-oviposition period. Meanwhile, a positive correlation between the expression of Vgs and fecundity was observed. Therefore, the nutrients provided by the food sources affected fecundity resulting in differential expression of Vgs. Vitellogenin expression can be used as a molecular marker of fecundity of N. cucumeris.
