| The blood feeding of a population of Cx. nigripalpus from Parque Ecológico do Tietê (PET) was investigated using an indirect ELISA protocol. Mosquitoes were captured outside houses. Five hundred sixteen engorged females collected in a reforested area and 25 in an open area were tested. Rodents and dogs were the most common blood sources, accounting for approximately 65.3% of blood meals. Human blood was detected in 10.9%, dog blood in 26.1%, chicken blood in 2.4%, and rodent blood in 39.2% of the 541 insects tested. ELISA failed in identifying the blood sources of 233 engorged females, indicating that the mosquitoes may have fed on a host which was not tested. One hundred six individuals were positive for more than one host. The unweighted human blood... |

| Insecticide application is the main way to control Diaphorina citri. However, it causes environmental contamination, has a negative impact on beneficial organisms, and leads to psyllid resistance. The essential oil of Piper aduncum has low toxicity towards the environment and contains dillapiol, which was proven to be effective against several crop pests. Here, we studied its efficacy against nymphs and adults of D. citri under laboratory conditions. Oils with three concentrations of dillapiol (65.2%, 76.6%, and 81.6%) at 0.5%, 0.75%, and 1.0% dilutions plus 0.025% adjuvant were tested. All treatments caused 90?100% mortality in nymphs. Topical treatments with oil containing 76.6% and 81.6% of dillapiol at 0.75% and 1% dilutions were effective (mortality... |

| Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncopeltus fasciatus and Rhipicephalus (Boophilus) microplus. Up to now, 102 secondary metabolites have been detected in the fractions, among them monoterpenes, sesquiterpenes and two triterpenes which were obtained from the species, Eugenia sulcata, Pilocarpus spicatus, Manilkara subsericea, Myrciaria floribunda and Zanthoxylum caribaeum. These secondary plant metabolites are considered of interest for the... |

| This work reports the results of sandfly collections in several places, during 2001 and 2002, in Bom Sucesso, Jardim Alegre, Kaloré, Londrina and Sabáudia municipalities, North of the State. The sandflies catches were performed with Shannon and Falcão traps in domiciliary areas, domestic animal shelters, barns and in the forest. A total of 4,019 specimens of 8 species were captured. Nyssomyia whitmani predominates in all of the municipalities. The species Migonemyia migonei, Nyssomyia neivai and N. whitmani may be involved in the epidemiology of American Tegumentary Leishmaniasis in this state. |

| The Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Liviidae) is one of the main pests of world citriculture, since it is a vector of the phloem-limited bacteria Candidatus Liberibacter spp. associated with huanglongbing (HLB). For this reason, the population control of D. citri with widespectrum insecticides has been one of the main tools used by growers to reduce the psyllid population and the disease spread in the citrus groves. Despite the high efficacy, the overuse of insecticides can affect the effectiveness of natural enemies [especially Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae), a nymphal ectoparasitoid of D. citri, and favor the process of selection of resistant population to the insecticides, target-pest resurgence and... |
