A 4-component sex pheromone of the Chilean fruit leaf roller Proeulia auraria (Lepidoptera: Tortricidae) Ciencia e Investigación Agraria
Reyes-Garcia,Luis; Cuevas,Yuri; Ballesteros,Carolina; Curkovic,Tomislav; Löfstedt,Christer; Bergmann,Jan.
L. Reyes-Garcia, Y. Cuevas, C. Ballesteros, T. Curkovic, C. Löfstedt, and J. Bergmann. 2014. A 4-component sex pheromone of the Chilean fruit leaf roller Proeulia auraria (Lepidoptera: Tortricidae). Cien. Inv. Agr. 41(2):187-196. The Chilean fruit leaf roller Proeulia auraria is a pest of economically important fruit species. Two compounds attractive to males have been identified as (E)-11-tetradecenyl acetate (E11-14:OAc) and (E)-11-tetradecenol (E11-14:OH) and are currently being used in Chile to monitor this species. Preliminary experiments carried out by our group suggested that the 2-compound mixture might not be optimal for the attraction of males, which prompted us to reinvestigate the sex pheromone of P. auraria in the present study. The pheromone...

Influence of different plants substrates on development and reproduction for laboratory rearing of Pseudococcus calceolariae (Maskell) (Hemiptera: Pseudococcidae) Ciencia e Investigación Agraria
Zaviezo,Tania; Cadena,Elizabeth; Flores,M. Fernanda; Bergmann,Jan.
The citrophilus mealybug, Pseudococcus calceolariae, is a polyphagous pest that has a major impact on fruit crops in central Chile, and is of quarantine importance for many markets. To study many control alternatives, it is important to develop efficient rearing protocols. The objective of this work was to determine mealybug development on three different plant substrates: sprouted potatoes, lemon fruits and Butternut squash. Insects were inoculated on the substrates, maintained at 25 °C and in total darkness until completing their development. Every one to 4 days, advancement on the development was checked by counting the exuvia. Mean developmental time for each stage, adult longevity, fecundity and fertility were determined. Preimaginal developmental...
