13. Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug Euschistus heros.
The objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a

14. Fatores determinantes do ataque de Neoleucinodes elegantalis ao tomateiro / Factors determinating the attack of Neoleucinodes elegantalis on tomato
The small tomato borer Neoleucinodes elegantalis (Lepidoptera: Crambidae) is considered a major pest due to serious damage in tomato. For the planning of strategies and tactics of management of N. elegantalis is essential to determine the factors that affect population dynamics and knowledge of stages and key factors of mortality. Therefore, objective of thi

17. Release of Trichogramma pretiosum (Hym.: Trichogrammatidae) and evaluation of Trichogrammatidae on egg masses of Spodoptera frugiperda (Lep.: Noctuidae) in corn / LIBERAÇÃO DE Trichogramma pretiosum (Hym.: Trichogrammatidae) E AVALIAÇÃO DE Trichogrammatidae EM POSTURAS DE Spodoptera frugiperda (Lep.: Noctuidae) NA CULTURA DO MILHO
Fall armyworm, Spodoptera frugiperda (J.E. Smith), is considered the major pest of corn. In general, the control of larvae is achieved with insecticides application, which can cause several environmental problems. In search of alternative control methods, egg parasitoids of the genus Trichogramma have been used in applied biological control programs, since t

19. Variação sazonal de Triozoida limbata (Hemiptera: Triozidae) e inimigos naturais em goiabeira / Seasonal variation of Triozoida limbata (Hemiptera: Triozidae) and natural enemies in guava plants
Triozoida limbata is one of the most important pests of guava plants. Their nymphs attack young leaves and buds, causing serious damages. Basic studies of population dynamics and determination of factors that regulate the population growth are necessary for the development of integrated programs management of this pest. Agents of natural biological control a

21. Ocorrência e bionomia de Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) e seu inimigo natural Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) em plantas de Eucalyptus globulus / Occurrence and bionomy of Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) and its natural enemy Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) in plants of Eucalyptus globulus.
Species of the genus Eucalyptus hosting several species of insects of the family Psyllidae. Among them, the specie Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) is considered the most harmful, causing damage to culture wherever it has been introduced. To control these hemiptera phytophage, treatment with insecticides proved to be costly and unsusta
