Phenoloxidase: a key component of the insect immune system
Entomologia Experimentalis et Applicata - Tập 142 Số 1 - Trang 1-16 - 2012
Isaac González‐Santoyo, Alex Córdoba‐Aguilar
AbstractThe innate immune system in insects is composed of a large variety of specific and non‐specific responses that are activated in response to the presence of foreign agents. One important element in such responses is the enzyme phenoloxidase (PO). Here, we review recent progress in PO research and discuss new applications in the emerging field of ecological i...... hiện toàn bộ
THE MECHANISM OF MALATHION‐RESISTANCE IN THE BLOWFLY CHRYSOMYA PUTORIA
Entomologia Experimentalis et Applicata - Tập 12 Số 3 - Trang 243-267 - 1969
M. G. Townsend, J. R. Busvine
ZUSAMMENFASSUNGDER MECHANISMUS DER MALATHION‐RESISTENZ BEI DER SCHMEISSFLIEGE CHRYSOMYA PUTORIA1. Der zu dieser Untersuchung benutzte resistente Stamm von Chrysomya putoria stammt aus dem Kongo, wurde aber vorher etwa 6 Jahre lang im Labor gezüchtet. Frühere Untersuchungen ergaben, daß (1.) seine Resistenz hochspezifisch ...... hiện toàn bộ
RELATION BETWEEN ELECTROPHORETIC ESTERASE PATTERNS AND ORGANOPHOSPHATE RESISTANCE IN MUSCA DOMESTICA
Entomologia Experimentalis et Applicata - Tập 8 Số 3 - Trang 163-174 - 1965
K. VAN ASPEREN, MARIET VAN MAZIJK, F. J. Oppenoorth
An Italian OP‐resistant strain C turned out to be heterogeneous for a gene on the 5th chromosome causing a difference in the mobility of an esterase in electrophoresis. Individuals containing only band 1 or 2 are homozygous for either allele, individuals containing esterase 1 and 2 are heterozygous. Two substrains were derived, E1 and E... hiện toàn bộ
THE DETOXICATION ENZYMES CAUSING ORGANOPHOSPHATE RESISTANCE IN THE HOUSEFLY; PROPERTIES, INHIBITION, AND THE ACTION OF INHIBITORS AS SYNERGISTS
Entomologia Experimentalis et Applicata - Tập 4 Số 4 - Trang 311-333 - 1961
F. J. Oppenoorth, K. VAN ASPEREN
A comparison of the breakdown enzymes in OP‐resistant houseflies and the ali‐esterase of susceptible flies shows differences as well as similarities. In general both are rapidly phosphorylated by the OP‐compounds, but only in the case of the breakdown enzymes dephosphorylation can take place. The rate of phosphorylation of the breakdown enzymes by the toxicants is s...... hiện toàn bộ
Further comments on analysis of covariance in insect dietary studies
Entomologia Experimentalis et Applicata - Tập 69 Số 3 - Trang 263-275 - 1993
David Horton, Richard A. Redak
AbstractRaubenheimer & Simpson (1992) recently discussed the advantages of using analysis of covariance in insect dietary studies as an alternative to the more conventional ratio‐based nutritional indices. We expand on some interpretations of Raubenheimer & Simpson and illustrate our points with examples from published and unpublished data sets. Specificall...... hiện toàn bộ
Analysis of covariance: an alternative to nutritional indices
Entomologia Experimentalis et Applicata - Tập 62 Số 3 - Trang 221-231 - 1992
David Raubenheimer, Sean L. Simpson
AbstractSome statistical problems are added to the growing list of cautionary tales regarding the use of the conventional, ratio‐based nutritional indices (RCR, RGR, ECI, AD and ECD). Analysis of ratios is based on the, probably unrealistic, assumption of an isometric relationship between denominator and numerator variables. Analysis of covariance (ANCOVA) makes le...... hiện toàn bộ
Methyl jasmonate‐induced nicotine production in Nicotiana attenuata: inducing defenses in the field without wounding
Entomologia Experimentalis et Applicata - Tập 80 Số 1 - Trang 213-220 - 1996
Ian T. Baldwin
AbstractThe functional significance of herbivore‐induced plant traits known to directly or indirectly influence herbivore performance remains largely untested under field conditions due to the difficulty of uncoupling the response to herbivory from the act of herbivory. The signals that activate many of the induced responses in plants are endogenously produced in r...... hiện toàn bộ
Multitrophic effects of herbivore‐induced plant volatiles in an evolutionary context
Entomologia Experimentalis et Applicata - Tập 97 Số 3 - Trang 237-249 - 2000
Marcel Dicke, Joop J. A. van Loon
AbstractHerbivorous and carnivorous arthropods use plant volatiles when foraging for food. In response to herbivory, plants emit a blend that may be quantitatively and qualitatively different from the blend emitted when intact. This induced volatile blend alters the interactions of the plant with its environment. We review recent developments regarding the inductio...... hiện toàn bộ
Absence of odour‐mediated avoidance of heterospecific competitors by the predatory mite Phytoseiulus persimilis
Entomologia Experimentalis et Applicata - Tập 92 Số 1 - Trang 73-82 - 1999
Arne Janssen, Ángelo Pallini, Madelaine Venzon, Maurice W. Sabelis
AbstractArthropods use odours associated with the presence of their food, enemies and competitors when searching for patches. Responses to these odours therefore determine the spatial distribution of animals, and are decisive for the occurrence and strength of interactions among species. Therefore, a logical first step in studying food web interactions is the analy...... hiện toàn bộ
Test for predation effects of single versus multiple species of generalist predators: spiders and their insect prey
Entomologia Experimentalis et Applicata - Tập 84 Số 2 - Trang 147-155 - 1997
Susan E. Riechert, Kendra L. Lawrence
AbstractThe prediction that single spider species (as exemplary generalist predators) limit associated prey populations to the same extent that species assemblages do was tested in a well controlled and replicated old field experiment involving the following treatments: (1) the natural spider assemblage (2) a numerically prominent web building spider, (3) a numeric...... hiện toàn bộ
