Parasitismo em Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) em Pomares de Citros em Montenegro, RS
Phyllocnistis citrella Stainton, the citrus-leafminer, is an important pest of citrus worldwide. Knowledge of natural parasitism levels is fundamental to the establishment of tactics of management and control of this species. This work aimed to evaluate the parasitism in two citrus orchards, one of ‘Montenegrina’ (Citrus deliciosa Ten.) and the other of ‘Murcott’ (C. sinensis (L.) Osbeck x C. r...
متن کاملSpatial distribution of parasitism on Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae) in citrus orchards.
Many species of microhymenopterous parasitoids have been registered on Phyllocnistis citrella, the citrus leafminer. The present study aimed to identify the spatial distribution pattern of the native and introduced parasitoids of P. citrella in two citrus orchards in Montenegro, RS. The new shoots from 24 randomly selected trees in each orchard were inspected at the bottom (0-1.5 m) and top (1....
متن کاملFactors affecting captures of male citrus leafminer, Phyllocnistis citrella Stainton, in pheromone-baited traps
The citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), is a world-wide pest of citrus (Heppner 1993) described originally in India (Stainton 1856). In the USA, it was initially found in Homestead, Florida and parts of Dade, Broward and Collier counties in 1993 (Heppner 1993). Its distribution is now widespread across Florida in citrus-growing regions, and is spread...
متن کاملSOMATIC EMBRYOGENESIS IN Citrus sinensis, C. reticulata AND C. nobilis x C. deliciosa
Most of the plant regeneration processes in citrus, through tissue culture, involve indirect somatic embryogenesis. The optimization of these processes is important for the development of in vitro plant improvement and micropropagation studies. Studies to evaluate the effect of different carbohydrates in somatic embryogenesis were conducted using calli from ‘Ponkan’ mandarin (Citrus reticulata,...
متن کاملResistance of citrus genotypes to Phyllocnitis citrella Stainton (Lepidoptera: Gracillariidae).
The development and reproduction of the citrus leafminer (CLM), Phyllocnistis citrella Stainton, were evaluated in six citrus genotypes in order to identify genotypes with resistance traits that could be applied in a program for the development of citrus varieties resistant to the citrus leafminer. Tests were conducted under controlled laboratory conditions (25 ± 1ºC, 70 ± 10% RH, and 14h photo...
