the biological parameters of sympiesis striatipes ashmead, one of the most abundant hymenopterous ectoparasitoid of phyllocnistis citrella stainton in ehime province of japan, were studied under laboratory and field conditions. the mean immature developmental time and adult longevity at different temperatures (22 to 31â°c), 50-70% rh and 12l: 12d photoperiod decreased as the temperature increas...

the citrus leafminer, phyllocnistis citrella stainton (lepidoptera: gracillariidae) is a major invasive pest of citrus in tunisia. in order to help the implementation of an efficient integrated management strategy, it was essential to assess the genetic diversity and population structure of the pest. for this purpose, random-amplified polymorphic dna-polymerase chain reaction (rapd-pcr) was app...

the biology of chrysocharis pentheus (walker) (hymenoptera: eulophidae), the most abundant endoparasitoid of phyllocnistis citrella stainton (lepidoptera: gracillariidae) in ehime prefecture, japan, was studied under laboratory and field conditions. the mean immature developmental time and adult longevity at different temperatures (22 to 31°c) under 50-70% rh decreased as the temperature increa...

Male, female and immature stages of Phyllocnistis tethys Moreira & Vargas sp. nov. (Lepidoptera; Gracillariidae) from the Atlantic Rain Forest, coastal mountains of southern Brazil, are described and illustrated, using both optical and scanning electron microscopy. A preliminary analysis of mitochondrial (COI) DNA sequences including putative members of congeneric species is also provided. The ...

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...

The objective of this work was to characterize the sexual behavior of the citrus leafminer, Phyllocnistis citrella Stainton, as the foundation for the isolation, identification, and synthesis of the complete sex pheromone of this species. Mating occurred in a time window of 2h, starting 1h before the onset of photophase. The large majority of tested insects mated in the first two days after eme...

The purpose of this work was to analyze the efficacy of Bacillus thuringiensis Berliner on the control of Phyllocnistis citrella Stainton (Lepidoptera: Phyllocnistidae) in laboratory and field trials. In the laboratory, four B. thuringiensis were used: Dipel (commercial formulation) tested at the concentrations of 25 x 10(6) and 25 x 10(8) spores/ml and the isolates K, 6, and 15 (collections of...

The sex pheromone of the leafminer Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) was deployed in a Florida citrus (Citrus spp.) grove by using a novel deployment device (IFM-413) containing SPLAT, a flowable formulation of an emulsified wax compound designed to provide slow release of semiochemicals. The device consisted of two disks connected by string. Each disk was loaded wit...

The citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), is an important pest of citrus that has spread around the world. The citrus leafminer invaded Florida in 1993 and rapidly colonized all citrus-growing areas. Despite the fact that the citrus leafminer has been studied extensively, gaps in our knowledge of its biology remain. One issue is how the citrus leafmine...
