3. Larval performance of the oriental fruit moth across fruits from primary and secondary hosts

Najar-Rodriguez, Adriana J., Bellutti, Nathalie and Dorn, Silvia (2013)

A common characteristic of many invasive herbivorous insects is their ability to utilize a broad range of host plants. By using various hosts in phenological succession, multivoltine herbivores may increase the number of successful annual generations, at the same time as...

4. Impact of different meadow mowing techniques on field invertebrates

Humbert, J.-Y., Ghazoul, J., Sauter, G.J. and Walter, T. (2010)

Low-input meadows are now recognized for their high biodiversity value and form an integral element of many agri-environmental schemes in Europe. Meadow mowing techniques, however, have become highly mechanized in recent decades and scientific knowledge on the direct impacts of...

5. Invertebrate herbivory along a gradient of plant species diversity in extensively managed grasslands

Unsicker, Sybille B., Baer, Nadine, Kahmen, Ansgar, Wagner, Markus, Buchmann, Nina and Weisser, Wolfgang W. (2006)

Increasing plant diversity has long been hypothesized to negatively affect levels of invertebrate herbivory due to a lower number of specialist insect herbivores in more diverse sites, but studies of natural systems have been rare. We used a planned comparison to study herbivory in...

6. Mortality rates and division of labor in the leaf-cutting ant, Atta colombica

Brown, Mark J. F., Bot, A. N. M. and Hart, Adam G. (2006)

Division of labor in social groups is affected by the relative costs and benefits of conducting different tasks. However, most studies have examined the dynamics of division of labor, rather than the costs and benefits that presumably underlie the evolution of such systems. In...

9. Molecular genetics and genomics generate new insights into invertebrate pest invasions

Kirk, Heather, Dorn, Silvia and Mazzi, Dominique (2013)

Invertebrate pest invasions and outbreaks are associated with high social, economic, and ecological costs, and their significance will intensify with an increasing pressure on agricultural productivity as a result of human population growth and climate change. New molecular genetic...

Sabotič, Jerica, Ohm, Robin A. and Künzler, Markus (2016)

Fruiting bodies or sporocarps of dikaryotic (ascomycetous and basidiomycetous) fungi, commonly referred to as mushrooms, are often rich in entomotoxic and nematotoxic proteins that include lectins and protease inhibitors. These protein toxins are thought to act as effectors of an...

15. Similarity and Specialization of the Larval versus Adult Diet of European Butterflies and Moths

Altermatt, Florian and Pearse, Ian S. (2011)

Many herbivorous insects feed on plant tissues as larvae but use other resources as adults. Adult nectar feeding is an important component of the diet of many adult herbivores, but few studies have compared adult and larval feeding for broad groups of insects. We compiled a data...

16. Herbivores and pathogens on Alnus viridis subsp. fruticosa in Interior Alaska

Mulder, Chrsita P.H., Roy, Bitty A. and Güsewell, Sabine (2008)

Parasite damage strongly affects dynamics of boreal forests. Damage levels may be affected by climate change, either directly or indirectly through changes in properties of host trees. We examined how herbivore and pathogen damage in Alnus viridis subsp. fruticosa (Rupr.) Nym....

19. Parasitism and life history in social insects

Schmid-Hempel, Paul (2006)

Parasites are ubiquitous and present a formidable challenge for social insects. Studies, especially on the model system of the European bumble bee, Bombus terrestris, and its parasites have shown that parasitism affects almost any trait that characterizes the life history...

24. Sperm influences female hibernation success, survival and fitness in the bumble–bee Bombus terrestris

Baer, Boris and Schmid-Hempl, Paul (2005)

We present evidence that in the absence of the transfer of male gland compounds in the ejaculate as well as of behavioural male traits, such as mate guarding or harming of females, sperm itself affects female life-history traits such as hibernation success, female longevity and...

25. Embodied linearity of speed control in Drosophila melanogaster

Medici, V. and Fry, S.N. (2012)

Fruitflies regulate flight speed by adjusting their body angle. To understand how low-level posture control serves an overall linear visual speed control strategy, we visually induced free-flight acceleration responses in a wind tunnel and measured the body kinematics using...

29. Specific versus nonspecific immune defense in the bumblebee, Bombus terrestris L.

Mallon, E.B., Loosli, R. and Schmid-Hempel, P. (2003)

Hosts vary in both their strength of response to a general immunological insult and in their specific susceptibility to different parasite species or different strains of the same parasite. The variation in the general immune response is considered a result of the costs imposed by...

33. A distinct infection cost associated with trans-generational priming of antibacterial immunity in bumble-bees

Sadd, Ben M. and Schmid-Hempel, Paul (2009)

The adaptive value of facultative maternal adjustment of offspring immunity, or trans-generational immune-priming, will depend on the ecological background. In particular, where there is a mismatch between the immune adjustment and offspring environment, the immunological link...

34. Cytoplasmic incompatibility and host population structure

Engelstädter, J. and Telschow, A. (2009)

Many arthropod species are infected by maternally inherited bacteria that induce cytoplasmic incompatibility (CI). CI causes embryonic mortality in offspring when infected males mate with either uninfected females or with females that are infected with a different strain of...

35. Social life-history response to individual immune challenge of workers of Bombus terrestris L.

Moret, Yannick and Schmid-Hempel, Paul (2004)

Parasites typically reduce host survival or fecundity. To minimize fitness loss, hosts can make temporal adjustments of their reproductive effort. To date such plastic shifts of life-history traits in response to parasitism are only known from solitary organisms where infected...

39. Biology of the Epichloë-Botanophila interaction: An intriguing association between fungi and insects

Bultman, Thomas L. and Leuchtmann, Adrian (2009)

Epichloë fungi (Ascomycota: Clavicipitaceae) are endophytes of grasses that can produce epiphytic stromata on the culms of their hosts. The fungal stromata are visited by Botanophila flies for feeding and egg laying. We review research that has documented the heterothallic mating...

42. The psychology of eating insects: A cross-cultural comparison between Germany and China

Hartmann, Christina, Shi, Jing, Giusto, Alice and Siegrist, Michael (2015)

Based on their high nutritional value and low production costs, insects are an excellent and sustainable source of animal protein. In contrast to countries such as China, in Western societies, the consumption of insects is not rooted in traditional diet. Data for the present study...

43. Insect antimicrobial peptides show potentiating functional interactions against Gram-negative bacteria

Rahnamaeian, Mohammad, Cytryńska, Małgorzata, Zdybicka-Barabas, Agnieszka, Dobslaff, Kristin, Wiesner, Jochen, Twyman, Richard M., Zuchner, Thole, Sadd, Ben M., Regoes, Roland R., Schmid-Hempel, Paul and Vilcinskas, Andreas (2015)

Antimicrobial peptides (AMPs) and proteins are important components of innate immunity against pathogens in insects. The production of AMPs is costly owing to resource-based trade-offs, and strategies maximizing the efficacy of AMPs at low concentrations are therefore likely to be...
