Epichloë endophytes alter inducible indirect defences in host grasses
(Public Library of Science, 2014-06)
Epichloë endophytes are common symbionts living asymptomatically in pooid grasses and may provide chemical defences against herbivorous insects. While the mechanisms underlying these fungal defences have been well studied, ...
Contrasting plasticity in ovariole number induced by a dietary effect of the host plants between cactophilic Drosophila species
(MDPI, 2016-05)
Under the preference-performance hypothesis, natural selection will favor females that choose oviposition sites that optimize the fitness of their offspring. Such a preference-performance relationship may entail important ...
Cutaneous hypersensitivity induced in dogs and guinea-pigs by extracts of the tick Rhipicephalus sanguineus (Acari: Ixodidae)
(1995-12-01)
The cutaneous hypersensitivity induced by Rhipicephalus sanguineus tick extract in dogs (natural host) and guinea-pigs (laboratory host) was evaluated. The left ear of infested and control (tick-bite naive) dogs and ...
Inorganic elements in the fat bodies of Diatraea saccharalis (Lepidoptera: Crambidae) larvae parasitized by Cotesia flavipes (Hymenoptera: Braconidae)
(ELSEVIER SCIENCE INC, 2010)
Koinobiont parasitoids use several strategies to regulate the host`s physiological processes during parasitism. Although many aspects of host-parasitoid interactions have been explored, studies that attempted to assess the ...
Temporal Variation in the Sex Ratio of a Natural Population of a Multivoltine Gall-Inducing Braconid Wasp
(Springer/plenum PublishersNew YorkEUA, 2014)
Role of temperature and carbonate system variability on a host-parasite system: Implications for the gigantism hypothesis.
Biological interactions and environmental constraints alter life-history traits, modifying organismal performances. Trematode parasites often impact their hosts by inducing parasitic castration, frequently correlated with ...
