Population dynamics of the cattle tick Rhipicephalus (Boophilus) microplus in a subtropical subhumid region of Argentina for use in the design of control strategies por Canevari, Jose Tobias, Mangold, Atilio Jose, Guglielmone, Alberto, Nava, Santiago

“…The non-parasitic phase of R. microplus was characterized by a long total non-parasitic period observed after exposures of females from mid-summer to early autumn, a short total non-parasitic period observed after exposures of females from late winter to late spring, a short period of larval longevity in early and mid-summer, and no hatch of the eggs produced by females exposed in mid- and late autumn and winter. …”

La cría de gallinas ponedoras por Cantaro, Horacio Luis

“…Por otro lado, el empleo de jaulas en la cría de gallinas para producción de huevos ha sido motivo de grandes polémicas en Dinamarca, Inglaterra, Suecia y Suiza, por citar países donde ya se ha legislado al respecto, y en Inglaterra, por ejemplo, un tercio de los huevos vendidos en grandes supermercados provienen de granjas con gallinas en libertad -“free range eggs”-, con gran promoción y a precios que duplican el de los huevos comunes. …”

The dual benefit of plant essential oils against Tuta absoluta por Ben Abdallah, Saoussen, Riahi, Chaymaa, Vacas, Sandra, Navarro-Llopis, Vicente, Urbaneja, Alberto, Pérez-Hedo, Mertixell

“…The spray of tomato plants with either A. millefolium or A. sativum PEOs significantly reduced the number of T. absoluta eggs, larvae, and infested leaflets. Additionally, both PEO sprays did not affect the establishment and reproduction of the predator N. tenuis compared to the control. …”

Development of Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae) on Eucalyptus camaldulensis Dehnh. and Eucalyptus dunnii Maiden por Cuello, Eliana Marina, Lopez, Silvia Noemi, Andorno, Andrea Veronica, Hernandez, Carmen Marcela, Botto, Eduardo Norberto

“…We also identifed the meteorological variables associated with changes in the red gum lerp psyllid abundance. 3 The abundance of eggs, nymphs and adults stages of G. brimblecombei was signifcantly greater on E. camaldulensis than on E. dunnii in the 2 years of the survey. 4 Glycaspis brimblecombei development was complete on E. camaldulensis where all instars were present, even in the unfavourable seasons. …”

Wildflower strips enhance pest regulation services in citrus orchards por Mockford, Alice, Urbaneja, Alberto, Ashbrook, Kate, Westbury, Duncan

“…Orange tree canopies were sampled for natural enemies, and pest regulation services were quantified using sentinel prey cards baited with Ephestia kuehniella eggs. Natural enemy richness was greatest in canopies with SMWT, supporting a greater relative abundance of primary parasitoids and lower relative abundances of antagonists (ants) compared to the control. …”
