A quantitative framework for ovarian dynamics
TLDR
It is shown that ovaries only function at full capacity after a first host meal and hints towards anautogeny in this species and a quantitative framework based on a state space describing the different levels of egg maturation and resorption states is provided. Expand
Influence of age and diet on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae) a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae)
TLDR
The type of meal (insects or honey) did not significantly influence parasitoid activity, search and oviposition capacities, and females fed with honey solution significantly consumed less immature coffee borers. Expand
Mating and host density affect host feeding and parasitism in two species of whitefly parasitoids
TLDR
The results suggest that only mated female parasitoids with host‐feeding behavior should be released in crop systems to increase their bio‐control efficiency. Expand
Effect of food supply on reproductive potential of Eretmocerus warrae (Hymenoptera: Aphelinidae)
TLDR
Investigation of the effect of food supply on longevity, host feeding, fecundity and parasitism in E. warrae found that parasitoids lived significantly longer when given honey but no host than parasitoid given the other treatments. Expand
Effects of Food Deprivation on Host Feeding and Parasitism of Whitefly Parasitoids
ABSTRACT Most whitefly parasitoids kill whiteflies in one of two ways, by piercing the whitefly body with the ovipositor and laying an egg or by piercing the body and feeding on host fluids. TheExpand
Protein, lipid, and glycogen levels in the parasitoid Bracon hebetor Say (Hymenoptera: Braconidae).
This study compared the protein, lipid, and glycogen reserves in recently emerged unfed female and male Bracon hebetor Say (Hymenoptera: Braconidae) to those in 5- and 10-day-old wasps fed honey.Expand
Intraspecific Competition Between Adult Females of the Hyperparasitoid Trichomalopsis Apanteloctena (Hymenoptera: Chelonidae), for Domination of Cotesia kariyai (Hymenoptera: Braconidae) Cocoons
TLDR
Aggressive interactions between the females of the secondary hyperparasitoid Trichomalopsis apanteloctena (Crawford) (Hymenoptera: Chelonidae) were examined for control of cocoon clusters of their primary parasitoid host Cotesia kariyai (Watanabe). Expand
Host-feeding and oviposition by parasitoids on hosts of different fitness value: Influences of egg load and encounter rate
TLDR
A dynamic optimization model is presented for the decision to host feed or oviposit on hosts by female parasitoids and predicts that lower value hosts should be accepted for oviposition at a lower egg-load threshold. Expand
Egg contents in relation to host-feeding in some parasitic hymenoptera
Using transmission electron microscopy, egg content is studied in 10 parasitoid species, which either feed on host hemolymph or do not. As expected, hydropic eggs were found to contain little yolkExpand
Comparing and contrasting life history and development strategies in the pupal hyperparasitoids Lysibia nana and Gelis agilis (Hymenoptera: Ichneumonidae)
TLDR
It is suggested that several eco-physiological factors, as well as differing degrees of specialization amongst the guild of secondary hyperparasitoids attacking C glomerata cocoons, enable them to successfully co-exist in nature. Expand

Parasitoid communities: their size, structure and development
TLDR
The authors develop a system of categorizing parasitoids, based on a fundamental dichotomy in their biology, which allows them to make predictions about host range. Expand
Complementary Approaches to the Understanding of Parasitoid Oviposition Decisions
TLDR
This work discusses each of the oviposition decisions in light of natural selection theory to illustrate the utility of understanding the selective forces acting on ovipositing females. Expand
DENSITY-RELATED PARASITOID SEX-RATIO: INFLUENCE ON HOST-PARASITOID DYNAMICS
TLDR
Four models incorporating density-related parasitoid sex-ratio are presented and are shown to be locally stable over a broad range of host depression below carrying capacity, which are a characteristic feature of successful biological control programmes using natural enemies. Expand
The parasitoids of the aleyrodid Bemisia tabaci in Israel: development, host preference and discrimination of the aphelinid wasp Eretmocerus mundus
TLDR
Developmental history and behavior of Eretmocerus mundus Mercet, a parasitoid of Bemisia tabaci was studied at 25 °C and it was found that the second and third instars are preferred. Expand
Host-Parasitoid Population Interactions
TLDR
Their great diversity and the high levels of parasitism that they often inflict on host populations have made parasitoids popular subjects for ecological studies in the field and for studying foraging and oviposition behavior under controlled conditions. Expand
Optimal Foraging Theory: A Critical Review
TLDR
It follows that the proportion of individuals in a population foraging in ways that enhance their fitness will tend to increase over time, and the average foraging behavior will increasingly come to be characterized by those characteristics that enhance individual fitness. Expand
Aggregation in field parasitoid populations: foraging time allocation by a population of Diadegma (Hymenoptera, Ichneumonidae)
TLDR
While Diadegma may select and forage preferentially on plants with higher host density, they do not exhibit the tendency, predicted by some optional foraging models, to exploit progressively less profitable plants during a foraging bout. Expand
Host quality effects on sex ratio of the parasitic wasp Anisopteromalus calandrae (Chalcidoidea, Pteromalidae)
TLDR
Evidence was found for the hypothesis that in Anisopteromalus offspring sex-ratio depends on clutch size, and a simple model is proposed to describe the succession of sex-Ratio decisions made under different conditions of host quality. Expand
LABORATORY STUDIES OF COMPETITION AMONG THREE SPECIES OF HYMENOPTEROUS HYPERPARASITES
TLDR
Marietta was the most efficient; it eliminated the population of the host whereas Cheiloneurus and Pachyneuron were not able to do so, and the superiority of Marietta may be partly due to the fact that it is capable of utilizing its competitors as hosts, whereas they cannot develop upon it. Expand
