1. Host plants of insect-induced galls in areas of cerrado in the state of Goiás, Brazil
Most studies of the interactions between plants and gall-inducing (galling) insects have focused on the entomological aspects, few having addressed the diversity of galls in relation to the characteristics of the host plants. The objective of this study was to analyze the richness and composition of the community of host plants of galls in areas of cerrado (

2. Distribution and Habitat in Mexico of Dactylopius Costa (Hemiptera: Dactylopiidae) and their Cacti Hosts (Cactaceae: Opuntioideae)
The distribution pattern of species of the genus Dactylopius Costa in Mexico was analyzed in relation to the distribution of their host plants (subfamily Opuntioideae) to evaluate the specificity of the insect-host association. The distribution of Dactylopius currently recognized is narrower than that of its hosts and probably is not representative. Therefor

3. Architectural changes in larval leaf shelters of Noctuana haematospila (Lepidoptera: Hesperiidae) between host plant species with different leaf thicknesses
Insect-food-plant associations have been shown to be influenced by the chemical, physical and nutritional characteristics of plants. We suggest that among insect larvae that use leaf material to build shelters, food-plant use may be constrained by differences in host leaf structure, illuminating a rarely investigated aspect of insect-plant interactions.

4. Effect of both host plant and mating disruption technique on the reproductive behavior of Leucopteta coffeella (Lepidoptera: Lyonetiidae) / Efeito da planta hospedeira e da técnica da confusão sexual no comportamento reprodutivo de Leucoptera coffeella (Lepidoptera: Lyonetiidae)
The present thesis had the aim to study the importance of the host plant to the reproductive behavior of L. coffeella. At first, the following aspects were evaluated: (i) the effect of the reproductive condition of females in response to host plant volatiles; (ii) if mating proportion, initiation time and copulation duration are affected by the presence of v

5. Correlating the infestation of fruit flies (Diptera: Tephritidae and Loncheidae) to the guava, peach and loquat trees phenology / Infestação de moscas-das-frutas (Diptera: Tephritidae e Lonchaeidae) relacionada à fenologia da goiabeira (Psidium guajava L.), nespereira (Eriobotrya japonica Lindl.) e do pessegueiro (Prunus persica Batsch)
Field experiments were conducted in three orchards in Monte Alegre do Sul, SP, each containing either a collection of strains of peach (September to October), guava (January to April) or loquat (August to September), during 2002 and 2003. Three strains of guava (Guanabara, L7P28 and 252), two of loquat (Precoce Campinas and Precoce 264-54) and three of peach

6. Identificação de atividades ATPásica e Amilásica em larvas de Pachymerus nucleorum (Fabricius, 1792) (Coleoptera: Chrysomelidae: Bruchinae)
ABSTRACT - CHAPTER I - Pachymerus nucleorum (Fabricius, 1792) is a beetle specie of the Bruchinae sub-family, family Chysomelidae, that principal host of this insect is a palm babassu (Orbinya spp). The objective of this work was identify and to characterize the ATPase activity in P. Nucleorum larvae. The P. nucleorum larvae guts were discartated and the gre

7. Efeitos do sexo, do vigor e do tamanho da planta hospedeira sobre a distribuição de insetos indutores de galhas em Baccharis pseudomyriocephala Teodoro (Asteraceae)
Several hypotheses have been proposed to explain the patterns of host plant utilization by herbivorous insects in natural communities. We tested four hypotheses aiming to understand the pattern of attack by gall-inducing insects on the dioecious shrub, Baccharis pseudomyriocephala (Asteraceae). The shrub occurs in the Parque Estadual do Itacolomi, Southeaste

8. Variação espacial na densidade, riqueza e composição de especies de insetos associados a capitulos de Senecio brasiliensis (Asteraceae)
This thesis was divided in two chapters. In chapter I, I investigated the factors responsible for the variation of insects density per plant in Senecio brasiliensis populations. I also related the insects local density and its geographic distribution. In chapter 11,I ana1yzedthe factors responsible for the variation of insect richness per plantoI also invest

9. Dynamics of Baculovirus Growth and Dispersal in Mamestra brassicae L. (LepidopteraNoctuidae) Larval Populations Introduced into Small Cabbage Plots
The nuclear polyhedrosis virus of Mamestra brassicae has been studied in larval populations of the moth introduced into small plots of cabbages. Primary dispersal of virus from single foci of infected larvae resulted from enhanced movement of the larvae, which colonized new plants logarithmically. Virus growth within the host population was quantified, and i

10. A quantitative threshold for nest-mate recognition in a paper social wasp
Nest-mate recognition is fundamental for protecting social insect colonies from intrusion threats such as predators or social parasites. The aggression of resident females towards intruders is mediated by their cuticular semiochemicals. A positive relation between the amount of cues and responses has been widely assumed and often taken for granted, even thou
