Influence of age and diet on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae) a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae)
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.
Reproductive Biology and Functional Response of Dineulophus phtorimaeae, a Natural Enemy of the Tomato Moth, Tuta absoluta
- BiologyJournal of insect science
The ovigeny strategy of D. phtorimaeae was analyzed throughout the adult female lifetime, and the functional response of females offered a type I functional response to T. absoluta, and egg production resulted in extremely synovigenic behavior.
A quantitative framework for ovarian dynamics
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.
Mating and host density affect host feeding and parasitism in two species of whitefly parasitoids
The results suggest that only mated female parasitoids with host‐feeding behavior should be released in crop systems to increase their bio‐control efficiency.
Effect of food supply on reproductive potential of Eretmocerus warrae (Hymenoptera: Aphelinidae)
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.
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.…
Effects of Food Deprivation on Host Feeding and Parasitism of Whitefly Parasitoids
- BiologyEnvironmental entomology
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. The…
Intraspecific Competition Between Adult Females of the Hyperparasitoid Trichomalopsis Apanteloctena (Hymenoptera: Chelonidae), for Domination of Cotesia kariyai (Hymenoptera: Braconidae) Cocoons
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).

Host-feeding and oviposition by parasitoids on hosts of different fitness value: Influences of egg load and encounter rate
- BiologyJournal of Insect Behavior
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.

The Effect of Resorbing Eggs upon the Sex Ratio of the Offspring in Nasonia Vitripennis (Hymenoptera, Pteromalidae)
The effect of availability of host puparis upon the sex ratio of the parasite Nasonia vitripennis has been studied and it is suggested that the increase in the percentage of males is related to the increased in the number of eggs undergoing resorption in the ovarioles at the time of oviposition.
Host Utilization by Bracon hebetor
The rates of accumulation and utilization of these hosts are a significant part of the natural dynamics of parasite populations and may be manipulated for pest management.
Habrobracon Brevicornis Wesm
I have submitted the insect in all of its stages of life to the action of temperatures varying from in the neighborhood of zero through freezing to the death point of 46Â° C., in an air conditioning chamber, and found that it has reacted in a special way.
An Interesting Habit of a Wax Moth Parasite.
During the fall of 1916, while rearing the bee moth, Galleria mellonella in the insectary for experimental purposes, a Pteromalid parasite Dibrachys clisiocampae Fitch† was observed to be very common…
The Influence of Diet upon the Adult Life Span of Two Species of Bracon
In Bracon, the life span of the females seems to be independent of their fecundity, and the genotype of the organism is a determining factor in the role of nutrition in relation to longevity.

Comparative Behavior and Competition Between Two Aphid Hyperparasites: Alloxysta victrix and Asaphes californicus (Hymenoptera: Cynipidae; Pteromalidae)
The numerical abundance and apparent competitive superiority of Alloxysta over AsAPhes in previous field studies is due not merely to its greater specificity and higher searching efficiency, but to its ability to compete successfully with Asaphes by increasingly surviving attack the later this occurs during its development inside the mummy.
Biology and Distribution of Tetrastichus incertus1, a Parasite of the Alfalfa Weevil2
Results from laboratory experiments indicate that both photoperiod and parent parasites have effects on incidence of larval diapause.
Influence of Continuous Light on Oöcyte Maturation in Bracon hebetor
Because continuous light stimulated oocyte maturation in B. hebetor and decreased the reproductive potential of the host insect, the Indian meal moth, Plodia interpunctella, the use of light provides a potential means for developing more effective biological control methods against P. interp punctella.
