RESUMO
Pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. Taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. We combined molecular analysis of three DNA markers (28S-D2, cytochrome oxidase I and internal transcribed spacer 2) with morphological examination, for the identification of 176 specimens collected from 40 mealybug populations infesting various crops and ornamental plants in Egypt and France. This combination of DNA and morphological analyses led to the identification of 17 species: seven in Egypt (Planococcus citri (Risso), Planococcus ficus (Signoret), Maconellicoccus hirsutus (Green), Ferrisia virgata (Cockerell), Phenacoccus solenopsis Tinsley, Phenacoccus parvus Morrison and Saccharicoccus sacchari (Cockerell)) and 11 in France (Planococcus citri, Pseudococcus viburni Signoret, Pseudococcus longispinus (Targioni-Tozzetti), Pseudococcus comstocki (Kuwana), Rhizoecus amorphophalli Betrem, Trionymus bambusae (Green), Balanococcus diminutus (Leonardi), Phenacoccus madeirensis Green, Planococcus vovae (Nasonov), Dysmicoccus brevipes (Cockerell) and Phenacoccus aceris Signoret), Pl. citri being found in both countries. We also found genetic variation between populations considered to belong to the same species, justifying further investigation of the possible occurrence of complexes of cryptic taxa.

One-hundred women requesting voluntary surgical sterilization were included and enrolled into four groups (each n = 25). Four sterilization modalities were used namely: Falope ring, electrocoagulation, clip and Pomeroy ligation. The circulating levels of hemoglobin, hematocrit, serum iron and total iron binding capacity were studied before sterilization and at 3, 6 and 12 months thereafter. No significant changes were observed at 3 and 6 months post-sterilization. At 12 months a significant increase in the hemoglobin and serum iron was observed with a significant decrease in total iron binding capacity. Falope ring, clip and Pomeroy ligation were of a higher rank in this context versus electrocoagulation.
