| A reprodução de parasitóides apresenta etapas interligadas e a idade de hospedeiros e parasitóides pode afetar o desenvolvimento desses últimos. Características biológicas de fêmeas de Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae), com até 96 horas de idade, foram estudadas em pupas do hospedeiro alternativo Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae). Cada pupa de A. gemmatalis com 0-24, 24-48, 48-72 ou 72-96 horas de idade, foi oferecida ao parasitismo por 10 fêmeas de T. diatraeae com 0-24, 24-48, 48-72 ou 72-96 horas de idade, por 24 horas à 25 ± 2oC, umidade relativa de 70 ± 10% e fotofase de 14 horas. A emergência, o número de descendentes, a duração do ciclo, a razão sexual, a longevidade e largura da cápsula... |

| Cassava is the sixth most important crop in the world, and it is attacked by many pests, such as Erinnyis ello (L.) (Lepidoptera: Sphingidae). This lepidopteran pest has natural enemies that can efficiently control its population, such as Trichogramma spp. (Hymenoptera: Trichogrammatidae). The objective of this research was to assess the flight capacity, parasitism and emergence of Trichogramma pretiosum, T. marandobai and T. demoraesi and to select the most efficient species among them for biological control programs. The flight capacity of these species was assessed in test units consisting of a plastic PVC cylinder with a rigid, transparent plastic circle on the upper portion of the cylinder and an extruded polystyrene disk to close the bottom of the... |

| We studied the effect of environmental complexity and plant architecture on the abundance of the Edessa rufomarginata bugs in pastures and cerrado areas and its biology. We observed higher number of bugs on Caryocar brasiliense trees in the cerrado than pasture areas. Bugs were more abundant on leaves and branches rather than fruits. Caryocar brasiliense had greatest fruit production on pasture than in the cerrado areas. The abundance of bugs was correlated positively with aluminum, organic matter, and tree height, but negatively correlated by soil pH. Productivity of C. brasiliense were negatively correlated with aluminum, pH, and number of bugs, but positively correlated with phosphorus and calcium. The number of eggs per clutch was 14.3, their viability... |
