| Abstract Cashew, Anacardium occidentale L. (Anacardiaceae), is one of the most important sources of agricultural income in northeastern Brazil, but many of the arthropods associated with the crop have yet to be identified. We describe here for the first time the damage caused by Holopothrips fulvus (Morgan) (Thysanoptera: Phlaeothripidae) to dwarf-cashew trees cultivated in the municipality of Pacajús, Ceará, Brazil. Leaf tissue injuries were caused by the sucking mouthparts of the insect and were characterized by dark necrotic spots on the epidermis that resulted in yellowing, wilting and, ultimately, abscission of the leaves. H. fulvus also fed on developing kernels and pseudofruits producing injuries that manifested in the form of chlorotic specks.... |

| Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions. Culex (Culex) saltanensis Dyar, 1928 is becoming frequent and abundant in natural and artificial breeding sites in urban and rural areas of Brazil. This study contributes to the knowledge of the biology of a Brazilian strain of C. saltanensis. The development of specimens reared individually or grouped was observed. The study was conducted at a constant temperature of 27 ± 2°C, 14L:10D photoperiod and 80 ± 5% relative humidity. The immature stages were observed every 6 hours until adult emergence, which occurred in 12.29 days among individually reared specimens and in 13.12 days among group-reared specimens. Egg rafts for the experiment... |

| ABSTRACT Some native plants can survive the disturbances associated with agricultural activities, sometimes being considered weeds and objects of control practices. However, these plants can be very important to support populations of native insects in disturbed habitats. Alternanthera halimifolia (Lam.) Standl. (Amaranthaceae) is locally considered a weed, and here it is reported as the first host plant known for the Neotropical hairstreak Strymon davara (Hewitson, 1868) based on research performed in the coastal valleys of the Atacama Desert of northern Chile. Furthermore, field observations suggest that this is the only host of S. davara in this area. This case provides an example of the importance of a weed in the conservation of local populations of a... |

| Abstract Pair-wise competition produces asymmetric consequences for the interacting species, resulting in reduction of species fitness at the individual scale; however, little is known of the effects of competition on the allometric patterns of insects. In this study, we explored how competition, by means of pod infestation, affects the development of female and male individuals in the co-occurring bruchine beetles Merobruchus terani and Stator maculatopygus. We found differences between M. terani and S. maculatopygus in all morphometric traits, but no significant differences between males and females in either species. We also found, with an increasing degree of pod infestation, a positive trend in the pronotum, elytron and body weight of M. terani and a... |

| Com o objetivo de selecionar linhagens de Trichogramma para o controle de G. aurantianum, avaliaram-se as características biológicas de 13 linhagens/espécies deste parasitóide. A partir desta seleção, determinou-se o número ideal de T. pretiosum (linhagem G18) a ser liberado por ovo de G. aurantianum em testes de telado. O teste de seleção de linhagens/espécies foi realizado em câmara climatizada regulada a 25±1ºC, UR: 70 ± 10% e fotofase de 14h. O número ideal de parasitóides foi estimado em gaiolas recobertas com tecido do tipo "voile". A duração do ciclo de vida das 13 linhagens/espécies de Trichogramma variou de 10,2 a 11,9 dias. A linhagem Atp (T. atopovirilia) apresentou maior capacidade de parasitismo, com uma média de 23,3 ovos parasitados e 77,5%... |

| Three new cecidogenous Palaeomystella Fletcher (Lepidoptera, Coleophoridae, Momphinae), described herein, induce galls on stems and leaves of Melastomataceae species. They include: Palaeomystella tibouchinae sp. n., on Tibouchina barbigera (Naudin) Baillon, P. oligophaga sp. n., on Macairea radula (Bonpland) de Candolle and M. thyrsiflora de Candolle, and P. henriettiphila sp. n., on Henriettea succosa (Aublet) de Candolle. Adults, including male and female genitalia, larva, pupa, and galls are illustrated and described in detail. |
