Optical microscopy and scanning electron microscopy technics were aplied in order to describe, for the first time, the immature stages of Z. beaumonti Casey, 1899 reared on it's prey, Diaspis echinocacti (Bouché, 1833) (Homoptera, Diaspididae), the unique pest of Opuntia ficus-lndica Mill and Nopalea cochenillifera (L.) Salm-Dick (prickly-pear, Cactaceae), an impportant alternative food source for the cattle on drought áreas of Northeast of Brazil. Yellow eggs layed inside the scales, caraboid larvae without wax processes and pupae partially protected by the last exuvia presented the Scymninae pattern. |

The objective of this study was to evaluate the impact of oil extract of neem, Azadirachta indica, on the watermelon aphid Aphis gossypii and its natural enemy Cycloneda sanguinea. Toxicity bioassays were conducted with the commercial product DalNeem (1,475 g L-1 azadirachtin) at 0.0037 µg a.i. mL-1, 0.0074 µg a.i. mL-1 and 0.0148 µg a.i. mL-1, Malathion at 1 µg a.i. mL-1 and distilled water as a control treatment. The products were sprayed to watermelon leaf discs, and the insects were exposed to the product residues. The instantaneous population growth rate of A. gossypii and the survival of C. sanguinea larvae exposed to the different treatments were calculated. A decrease in the instantaneous population growth rate of A. gossypii with increasing... |

BACKGROUND: Changed temperature not only threaten agricultural production, but they also affect individual biological behavior, population and community of many insects, and consequently reduce the stability of our ecosystem. Insect's ability to respond to temperature stress evolved through a complex adaptive process, thus resulting in varied temperature tolerance among different insects. Both high and low extreme temperatures are detrimental to insect development since they constitute an important abiotic stress capable of inducing abnormal biological responses. Many studies on heat or cold tolerance of ladybirds have focused on measurements of physiological and biochemical indexes such as supercooling point, higher/lower lethal temperatures, survival... |

The study was done during the spring, summer and fall of 1998 and 1999. Samples were taken at random from legume crops and spontaneous plants adjacent to them in the province of León (Spain). Observations were made on the following crops: Medicago sativa, Phaseolus vulgaris, Pisum sativum, Cicer arietinum, Trifolium repens, Vicia fava, Trifolium pratense, Vicia ervilia, Lathyrus cicera, Lathyrus sativus, Trigonella foenum-graecum, Lupinus albus, Lupinus angustifolius and Lens esculenta. Twenty three families of spontaneous plants were observed. The aphid species and their population densities on the spontaneous plants and crop plants were recorded, as was the presence of members of the families Coccinellidae, Syrphidae and Chrysopidae. The plant families... |

In La Araucanía, the filbert aphid Myzocallis coryli (Goeze) is a pest that can cause various types of damage to hazelnut (Corylus avellana L.) including reduction in nut size and nut emptiness. M. coryli can also leave hazel leaves susceptible to the fungus known as fumagina (Capnodium sp.), which causes decreased photosynthesis, particularly during the period when the tree is storing reserves for the following season. Knowledge about the natural enemies of M. coryli in Chile is in its early stages compared with other countries where the hazelnut crop is more extensive. Indeed, only 13 entomophagous predators have been recorded in La Araucanía thus far, including one Hemerobiidae, one Syrphidae, one Cecidomyiidae and ten Coccinellidae. Of this last... |

In this work, we document the presence of Harmonia axyridis in Chile, an invasive coccinellid species that has had negative effects in other regions of the world, such as: impacts on non-target arthropods, invasions of houses and fruit damage. This species has been found in the last three years in the Metropolitan and Valparaíso regions, in crops, pine plantations and inside houses. We warn about the consequences of the introduction of this species to Chile and claim to take actions to avoid its spread in the country. |

Numerosas especies de artrópodos invernantes de la región pampeana utilizan a las gramíneas perennes como refugio. Las características estructurales y el tamaño de las plantas, así como su disposición espacial, condicionarían la disponibilidad de hábitat o de refugio y, en consecuencia, la selección de esas plantas por artrópodos invernantes. En este trabajo evaluamos la influencia del tamaño, el agrupamiento y la modificación de la arquitectura de plantas de Schizachyrium condensatum sobre la abundancia y la riqueza de artrópodos invernantes en su interior. En un borde de un área agrícola de la Pampa Ondulada se dispusieron plantas de distinto tamaño, desde 110 cm de altura (plantas grandes) a 70 cm de altura (plantas pequeñas), de manera aislada o en... |
