25. Development and rearing techniques of Palmistichus elaeisis (Hymenoptera: Eulophidae) in natural and alternative hosts / Desenvolvimento e técnicas de criação de Palmistichus elaeisis (Hymenoptera: Eulophidae) em hospedeiros natural e alternativo
This research was developed in the Laboratory of Biological Control of Insects of the Department of Animal Biology at the Federal University of Viçosa (UFV) in Viçosa, Minas Gerais State, Brazil. The objective was to evaluate the viability of pupae of Bombyx mori L., 1758 (Lepidoptera: Bombycidae) as an alternative host for Palmistichus elaeisis Delvare &L

26. Comparison between three ages of the parasitoid Cotesia flavipes in the parasitism of Diatraea saccharalis / Estratégias de parasitismo da vespa parasitóide Cotesia flavipes, Cameron, 1891 (Hymenoptera:Braconidae)
Cotesia flavipes is an endoparasitoid wasp introduced in Brazil to biologically control the host Diatraea saccharalis, commonly known as the sugar cane drill. These insects have been reared for more than thirty years in Brazil, in massal rearing creation laboratories. In times of good female productivity in massal rearing creation laboratories, the parasitoi

27. Biology of the first generation of a laboratory colony of Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) (Diptera: Psychodidae)
The phlebotomine sand flies Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) are very close and may be involved in the transmission of Leishmania spp. Ross, 1903 in Brazil. The biology of the first laboratory-reared generations of these species, descended from insects captured in Além Paraíba (N. intermedia) and Corinto (N. neiv

28. Choice and No-Choice Assays for Testing the Resistance of A. thaliana to Chewing Insects
Larvae of the small white cabbage butterfly are a pest in agricultural settings. This caterpillar species feeds from plants in the cabbage family, which include many crops such as cabbage, broccoli, Brussel sprouts etc. Rearing of the insects takes place on cabbage plants in the greenhouse. At least two cages are needed for the rearing of Pieris rapae. One f

29. Genetic and acclimatory variation in biophysical properties of insect cuticle lipids.
Epicuticular lipids provide the primary barrier to water loss in insects and other terrestrial arthropods. Using Fourier transform infrared spectroscopy, we found that the melting temperatures for these lipids in the grasshopper Melanoplus sanguinipes varied by over 10 degrees C between individuals. The most significant determinant of lipid melting temperatu

30. Contribution of anaerobic protozoa and methanogens to hindgut metabolic activities of the American cockroach, Periplaneta americana.
The ciliate Nyctotherus ovalis occurs in high numbers in the hindgut of the American cockroach (Periplaneta americana) and harbors methanogenic bacteria as endosymbionts. The contribution of these hindgut microorganisms to metabolic and developmental processes of P. americana was studied by comparing cultures of cockroaches in which the composition of the hi

31. Intraspecific competition in the speckled wood butterfly Pararge aegeria: Effect of rearing density and gender on larval life history
In insects, the outcome of intraspecific competition for food during development depends primarily upon larval density and larval sex, but effects will also depend on the particular trait under consideration and the species under study. Experimental manipulations of larval densities of a Madeiran population of the speckled wood butterfly Pararge aegeria conf

32. Characterization of Wolbachia Host Cell Range via the In Vitro Establishment of Infections†
Maternally transmitted bacteria of the genus Wolbachia are obligate, intracellular symbionts that are frequently found in insects and cause a diverse array of reproductive manipulations, including cytoplasmic incompatibility, male killing, parthenogenesis, and feminization. Despite the existence of a broad range of scientific interest, many aspects of Wolbac

33. Social exploitation of vitellogenin
Vitellogenin is a female-specific glucolipoprotein yolk precursor produced by all oviparous animals. Vitellogenin expression is under hormonal control, and the protein is generally synthesized directly before yolk deposition. In the honeybee (Apis mellifera), vitellogenin is not only synthesized by the reproductive queen, but also by the functionally sterile
