Glycoalkaloids of Wild and Cultivated Solanum: Effects on Specialist and Generalist Insect Herbivores
TLDR
Different GA profiles explain the feeding preferences of the different herbivores, and that domestication has altered the defensive capacity of S. tuberosum, a cultivated plant subject to severe defoliation by a specialist herbivore that may cue on the GAs.
Essential oil from Eupatorium buniifolium leaves as potential varroacide
TLDR
A bioprospecting program of the local flora searching for botanical pesticides to be used as varroacides was launched and three E. buniifolium EOs tested were active against Varroa in laboratory assays; however, there are differences that might be attributable to chemical differences found.
Conspecific females promote calling behavior in the noctuid moth, Pseudaletia adultera
TLDR
By calling more and extending her calling window in presence of conspecific females, a female may increase her chances of accessing males and the potential benefits need to be considered within an ecological context, considering factors such as migration, oviposition, and foraging.
Space use by Río Negro tuco-tucos (Ctenomys rionegrensis): Excursions and spatial overlap
TLDR
Comparisons of minimum convex polygons for these animals revealed spatial overlap between 3 pairs of neighboring adult females, consistent with an intermediate pattern of space use, suggesting that C. rionegrensis exhibits a spatial structure not previously documented among ctenomyids or other subterranean rodents.
Preference–performance in a specialist sawfly on congeneric host plants
TLDR
This study explored the preference–performance linkage in a monophagous sawfly, Tequus schrottkyi (Konow) (Hymenoptera: Pergidae), which feeds as larva on the wild potato Solanum commersonii Dunal (Solanaceae), and the nutritional quality of the plants was assessed, resulting in more larvae completing their development to the adult stage.
Reproductive behaviour of Crocidosema (=Epinotia) aporema (Walsingham) (Lepidoptera: Tortricidae): temporal pattern of female calling and mating.
TLDR
The results describe for the first time the temporal pattern associated to the reproductive behaviour of C. aporema, and provide evidence that this tortricid is monoandrous, and that pheromones are used in intersexual communication for mate finding.
First report of Tequus schrottkyi (Konow) (Hymenoptera: Pergidae) in Uruguay, and information about its host plant and biology
TLDR
This sawfly species is associated with Solanum commersonii, a native plant common in Uruguay and is unpalatable to a generalist predator, possibly due to defensive compounds sequestered from their host plant, known to contain toxic compounds.
Interacción planta-insecto: resistencia diferencial a la herbivoría en dos especies de solanum y su relación con la preferencia y performance de herbívoros generalistas y especialistas
Sex Pheromone of the Bud Borer Epinotia aporema: Chemical Identification and Male Behavioral Response
TLDR
Two EAD-active compounds are identified as sex pheromone components of E. aporema, including (Z,Z)-7,9-dodecadienol and (Z),Z-7, 9- dodecADienyl acetate (15:1 ratio), indicating that these two compounds are pherOMone components.
Synthesis and field evaluation of synthetic blends of the sex pheromone of Crocidosema aporema (Lepidoptera: Tortricidae) in soybean
TLDR
The pheromone traps were attractive for up to 40 days, even with small septum loads (0.1 mg) and low population levels, and the 1:1 mixture was the most efficient in capturing males.
