Density-Dependent Growth and Fitness in Dastarcus helophoroides (Coleoptera: Bothrideridae)
TLDR
Findings suggest six larvae per host would achieve the highest adult fitness and would enhance mass-rearing techniques as part of IPM strategies for longhorn beetles.
Parasitism of cassava mealybug by Anagyrus lopezi: Effects of varying host and parasitoid densities
TLDR
The objectives of this study were to understand the influence of host and parasitoid densities on functional response and mutual interference of the Parasitism of cassava mealybug by Anagyrus lopezi, by altering either the host or parasitoids density while keeping the other constant.
Host population density and presence of predators as key factors influencing the number of gregarious parasitoid Anaphes flavipes offspring
TLDR
It is suggested that in comparison to solitary parasitoids, the gregarious parasitoid A. flavipes can better respond to various external factors and can more flexibly change its population density.
Effect of supplementary nutrition on the reproduction and mating behaviour of Habrobracon hebetor (Hymenoptera: Braconidae)
TLDR
The survival of mated male wasps was markedly prolonged after feeding with different types of nutrients and that of unmated males were markedly prolonged except when provided with yeast solution, and providing female wasps with supplementary nutrition did not affect their longevity.
Predation of fruit and seed of Aloe pretoriensis - A little known effect on reproductive output in aloes
TLDR
Aloe pretoriensis serves as host to a variety of phytophagous insects and their associated parasitoids, which impacts considerably on its reproductive output with possible implications for the future conservation of this aloe species.
Reproductive strategy as a major factor determining female body size and fertility of a gregarious parasitoid
TLDR
It is demonstrated that the variable reproductive strategy (VRS) of wasp A. flavipes causes a plasticity in body size and future number of offspring, which is similar to the generally known “trade‐off” scheme.
Scarcity of hosts for gregarious parasitoids indicates an increase of individual offspring fertility by reducing their own fertility
TLDR
It was shown that with a scarcity of hosts, the mothers increased the number of their female offspring, and thus, they obtained more offspring in the F2 generation, and other costs and benefits of the gregarious strategy in relation to superparasitism were tested and discussed.
An intergenerational approach to parasitoid fitness determined using clutch size
TLDR
It is shown that with a range of hosts simultaneously utilized by female parasitoids, identical fertility in the F1 generation can lead to distinctly different fertility values in theF2 generation, which provides an intergenerational perspective for determining individual fitness of gregarious Parasitoids and new possibilities for the modelling of parasitoid population density.

Alternative hosts of Sclerodermus pupariae (Hymenoptera: Bethylidae), a larval parasitoid of the longhorn beetle Massicus raddei (Coleoptera: Cerambycidae).
TLDR
The results of the present study indicated that the biocontrol program using S.pupariae could have sustainable control effects on M.raddei, and the larvae of the two cerambycids always existed during the unfavorite developmental periods of M.myops.
Studies on Control Young Larvae of Massicus raddei(Coleoptera: Cerambycidae) by Applying Parasitoid Sclerodermus pupariae(Hymenoptera: Bethylidae) and its Supercooling Point
TLDR
The present study indicates that the parasitoid is a superior biocontrol agent of the oak longhorned beetle in its young larval stage.
The developmental strategies and related profitability of an idiobiont ectoparasitoid Sclerodermus pupariae vary with host size
TLDR
Assessment of host profitability revealed that medium‐sized hosts presented the best fitness return for the parasitoids, suggesting that this bethylid parasitoid can achieve a compromise in optimisation of the two most important fitness functions when encountering an abundance of different-sized hosts.
Effects of learning experience on behaviour of the generalist parasitoid Sclerodermus pupariae to novel hosts
TLDR
Findings suggested that adaptive learning significantly enhanced the ability of a generalist parasitoid to utilize a novel host and may provide a new approach to controlling non‐natural hosts using generalist Parasitoids.
Studies on biological control of Anoplophora glabripennis (Coleoptera:Cerambycidae) with a parasitoid, Sclerodermus guani (Hymenoptera:Bethylidae)
TLDR
It was indicated that good control results has been achieved with the parasitoid ratio and host 8-10:1 during releasing, and the field experiment showed that the 1st-3rd instar larvae of the cerambycid could also be controlled by the Parasitoid.
Host-Size Mediated Trade-Off in a Parasitoid Sclerodermus harmandi
TLDR
The existence of trade-off occurring during host-parasitoids interactions according to host size related quality is demonstrated by demonstrating the selection of the most profitable host size for parasitoid development.
Host–parasitoid community model and its potential application in biological control of cereal stemborers in Kenya
TLDR
A two-host–two-parasitoid model was constructed and indicated that the coexistence of stemborer host populations are determined by their population growth rates, the degree of aggregation of the parasitoids and their searching efficiency, and in the regions where both the invasive and the predominant native host species were suitable to either parasitoid species, stemborers densities would be reduced to and controlled at low densities.
Study on Optimal Parasitoid-host Ratio of Breeding Bethylid with Larvae of Monochamus alternatus
TLDR
The results showed that 3∶1 parasitoid-host ratio was the best choice for breeding these two species of ethylids regarding to each index mentioned above.
Host marking behavior in phytophagous insects and parasitoids
TLDR
The role of Marking Pheromones (MPs) as signals of brood presence in both phytophagous and entomophile insects is reviewed and it is suggested that MP systems are model systems for the study of animal signaling and its evolution.
