Larvae of a melanic phenotype of the Greater wax moth, Galleria mellonella, were selected for resistance to B. Survival assays conducted on cohorts of the selected S and non-selected NS lines revealed significantly increased resistance survival times of the 25 th generation of the S line to B.
Importantly, this S line did not show statistically significant cross-resistance to M. The defense responses of the S and NS lines to B. Mortality rate of selected line and non-selected line of G. However, during the early stages of topically-applied fungal infection, the cuticular PO activity in infected S, but not infected NS larvae, became elevated above uninfected larval levels at 24 h post inoculation pi for both B. This coincides with peak fungal germination and penetration activities. Cuticular phenoloxidase PO activity A , hemolymph phenoloxidase B , lysozyme-like C activity and encapsulation responses D in hemolymph of G.
Lysozyme-like activity was unchanged in all samples, irrespective of the insect line or treatment Figure 2C. However, this activity was significantly lower 24 h pi with B. Unlike B. Expression of seventeen immunity and putative stress management genes was investigated in the integument and fat body of uninfected control and fungal infected insects from both the S and NS lines. The expression data were complex, with some genes behaving differently under each experimental parameter.
However, several important trends can be reported. The majority of the studied genes were expressed at a lower basal level in uninfected control S larvae compared with the NS larvae, in both the integument and fat body. However, a group of genes coding for four putative stress-management factors Contigs , , , and one AMP Galiomicin exhibited different expression patterns, being slightly higher expressed in the integument but not the fat body of control S larvae compared with control NS insects 1.
Basal expression in uninfected S larvae A is illustrated as a fold change relative to NS uninfected larvae and the x-axis represents basal expression in NS larvae i. Fold induction in infected S larvae is calculated relative to the S uninfected expression B, C. Following topical fungal infection, the pattern of gene expression in the S-line insects infected with B. In the other groups i. NS insects infected with either fungal species, and in S insects infected with M.
The expression of most stress-management and immunity-related genes in the integument of these infected insects was also either unchanged or downregulated, although some AMP genes were upregulated in the integument of M. In contrast, in S-line insects infected with B. Furthermore, differences between gene expression in the two tissue locations was significant, i. Upregulation of AMP genes Gallerimycin, Galiomicin, Gloverin, Cecropin-D, 6-tox and Transferrin a siderophore was 5—times higher in fat body of NS and S fungi infected larvae compared with expression in integuments of infected insects Figure.
Selected insects with enhanced resistance to B. Both NS and S lines exhibited reduced fecundity as a consequence of melanism but this was at equivalent levels in both lines summarized in Table S2. The present study shows that insects can develop resistance to insect pathogenic fungi but the resistance is not absolute and is at a cost. A melanic morph of G. A combination of mechanisms was identified that can account for this resistance, some of which were specific for B. Both the S resistant and NS susceptible lines of this morph expressed a wide repertoire of inducible immune and putative stress management genes.
In the S line these resources were re-focussed to the integument.
By concentrating its energies to the first and most important barrier to infection, the host delayed pathogenesis by B. Similarly, infected S line insects exhibited higher cuticular PO activity but not plasma PO or lysozyme. It is possible the S line had evolved an enhanced Beauveria recognition apparatus allowing for a more coordinated and targeted response which would account for the increased activity in the integument but subdued activity in the fat body, the main hemopoietic organ.
The fat body occupies a large portion of the insect hemocoel and is the principle site for the synthesis of AMPs in insects exposed to immunogens, including pathogens, irrespective of point of contact or entry  ,  , . As far as we are aware, there are to date no reports of pathogen specific defense mechanisms involving re-allocation of systemic resources to localised tissues under or at risk of attack. This study shows elevated integumental expression of all but two of the examined putative stress management genes i. The fact that so many putative stress related genes were upregulated signifies their importance in defense responses yet their role is poorly understood and often overlooked.
By working in concert with the AMPs they probably mitigate damage and initiate repair resulting in the increased resistance observed in the S line to B. The importance of the putative stress-response genes is further emphasized in the M. The current study suggests that the resistance in the S line is heritable and multi-factorial, comprising several different physiological traits prioritised not only in terms of location but also timing as they were activated concomitant with the period of fungal penetration of the integument. For example, the elevated cuticular PO activity would inhibit fungal growth through synthesis of melanin and its precursors and through melanin partially shielding cuticular proteins from degradation by Pr1, a major cuticle degrading protease and virulence determinant produced by B.
Genes coding for antioxidants are also highly represented under the same conditions and may defend the host against reactive oxygen species generated by PO activity during cuticle penetration . Interestingly, cecropins do have antifungal activity but have been reported as ineffective against B. Current knowledge is very limited regarding the role in G.
Gloverin is not currently known to have any potent antifungal activity, however, putative antifungal and antimicrobial peptides may fulfil different and currently unrecognized roles in different hosts and under specific infection conditions. In isolation, each of these responses are unlikely to sufficiently impart the observed resistance, however, their impact may be amplified by a synergy between these and other as yet unidentified traits.
There is growing evidence that insects can acquire long-term protection against pathogens through immune priming or transfer from the parent to the offspring, a phenomenon referred to as transgenerational immune priming  , . The current study shows the 25 th generation S line larvae exhibit specific, enhanced resistance to B. An earlier but weaker resistance was also observed in the S line which suggests a heritable and amplified immunocompetence. These observations warrant further investigations of possible underlying genetic and epigenetic mechanisms of resistance.
Melanism is strongly correlated with general pathogen resistance with this trait often being accompanied by a trade off in fecundity, development time and even expression of selected immune components such as lysozyme  ,  ,  , . In the current study, the pupal weight of the melanic S and NS lines which is directly correlated with fecundity was similar and already pushed close to minimum.
It could be argued that resistance in S line insects would increase further with time but to meet the increased demand on resources may result in untenable sacrifices. This is in marked contrast with insects developing resistance to synthetic chemical insecticides where a slight change can have a profound effect  ,  ,  whereas resistance to B.
Increased insect resistance to a strain of B. Firstly, we show that there is no cross resistance to other fungi so the extra investment in defense offers no benefit against other pathogens introduced or natural. Secondly, the investment in defense is at the expense of fecundity. Thirdly, the downregulation of the AMPs will probably predispose the insect to opportunistic microbial pathogens. In conclusion, this work reports a previously overlooked adaptation strategy of an insect to a widespread, natural pathogenic fungus. This directional selection with B.
However, the less fecund insects are probably at no evolutionary advantage in the wild, and we postulate that the risk is small of fungal biological control agents failing in the field. The starting population was separated into two lines: one line was exposed to the insect pathogenic fungus Beauveria bassiana and selected for increased resistance to the pathogen S line , and the other line was the non-selected untreated control NS line. The pertinent phenotypic attributes of these lines are summarized in Table S2. The defense responses of the 25 th generation of the S and NS insects to B.
Full details of insect rearing and selection are provided in the Text S1. The susceptibility of S and NS lines to B. Unlike the previous generations, insects from the 25 th generation were not exposed to fungi until they were used for these experiments. Each insect was dipped in an aqueous suspension of the pathogen for 10 s using a concentration of 7.
To determine if there was cross-resistance to other species of fungal pathogen, repeat assays were performed as above, using the insect pathogenic fungus Metarhizium anisopliae isolate P Larvae were observed daily for 10 days up to pupation for both B. The emergent adults were monitored for several days to see what percentage were infected with the pathogen.
All dead insects were removed and examined to confirm the cause of death. All insects used in these experiments were 6 th instar larvae raised in the same cohort. The experiment was repeated independently three times. The total number of individuals used from each line was for the B. Uninfected insects were used as a control. Full details are provided in the Text S1. To determine melanotic encapsulation responses to fungal infection, encapsulation assays were performed in NS and S larvae.
Nylon monofilament implants were retrieved from the hemocoel and examined using image analysis software to quantify the extent of melanization. Full details are provided in the Text S1 and experiments were repeated independently three times. Antibacterial activity in hemolymph plasma was determined by a zone-of-clearance assay using freeze-dried Mirococcus lysodeikticus as a substrate suspended in agarose.
The expression of a range of G. Seventeen target genes were investigated, coding for the antimicrobial peptides gallerimycin, galiomicin, gloverin, cecropin D and 6-tox, the siderophore transferrin, the insect metalloproteinase inhibitor IMPI , one linked to immune signaling Contig , three coding for heat-shock proteins HSP, contig and whose activities ameliorate stress  , two coding for enzymes dealing with oxidative stress Contigs and , one linked to G-protein coupled receptor activity and stress response Contigs , one involved in anti-apoptosis activity Contig and two involved with cell proliferation Contigs and Full details are provided in the Text S1 and Table S3.
The following life history traits were monitored in NS and S insects: larval development time from egg hatching to onset of pupation and pupal weight. Data analyses were performed using GraphPad Prism v4. Data were checked for normal Gaussian distribution using the Agostino-Pearson omnibus test, and if abnormally distributed a more conservative non-parametric analysis was applied. Larvae from bioassay experiment uninfected with the fungi all survived the duration of the experiment, for this reason, the uninfected treatment was ignored in the statistical analysis.
Differences in life history traits were compared by non-parametric t-test Mann-Whitney. AMP gene expression in integuments of infected insects.
