TLDR
It is demonstrated that the level of parasitism is highest for lower levels of C. cinctus infestation, in fields where parasitoids are either scarce or abundant, and developed redistribution strategies for introducing these parasitoid at sawfly infested locations where they are currently present at negligible levels are discussed.About:

Sex differences in phenotypic plasticity affect variation in sexual size dimorphism in insects: from physiology to evolution.
TL;DR: Adaptive hypotheses proposed to explain sex differences in plasticity, including those that predict that plasticity will be lowest for traits under strong selection (adaptive canalization) or greatest for trait under strong directional selection (condition dependence), are explored.

Causes and consequences of cannibalism in noncarnivorous insects.
TL;DR: Cannibalism can be adaptive by improving growth rate, survivorship, vigor, longevity, and fecundity, and it also can play an important role in regulating population density and suppressing population outbreaks, stabilizing host plant-insect relationships, and reducing parasitism rates.

TL;DR: This chapter discusses Grasshoppers and locusts, a group of insects that have a tremendous impact on agricultural production throughout the world and are referred to collectively by the common name “acridoids.”

Biology and Integrated Management of Wheat Stem Sawfly and the Need for Continuing Research
TL;DR: The wheat stem sawfly, Cephus cinctus (Hymenoptera: Cephidae), is historically one of the most important economic insect pests in the northern Great Plains of North America as discussed by the authors.

WASP PARASITOID DISRUPTION OF HOST DEVELOPMENT: Implications for New Biologically Based Strategies for Insect Control*
Nancy E. Beckage,Dale B. Gelman +1 more
TL;DR: An overview of the manipulative capabilities of wasp-injected calyx fluid containing polydnaviruses and venom, as well as the Parasitoid larva and the teratocytes that originate from the serosal membrane that surrounds the developing embryo of the parasitoid are presented.

Fitness consequences of cannibalism in the fall armyworm, Spodoptera frugiperda
Jason W. Chapman,Trevor Williams,Ana Escribano,Primitivo Caballero,Ronald D. Cave,Dave Goulson +5 more
TL;DR: The only detectable fitness benefit associated with cannibalism was a positive correlation between the number of victims consumed and development rate under conditions of low food availability; on balance, cannibalism appears to be costly.
SADIE: software to measure and model spatial patterns
TL;DR: The current status of the SADIE system for measuring and testing for spatial pattern in data from a single species and for spatial association in data for two species is outlined.

A new index of aggregation for animal counts.
Joe N. Perry,Mark Hewitt +1 more
TL;DR: A new index is described that is especially appropriate for measuring the aggregation of entomological data in the form of counts per sample unit and that can make use of spatial information when it is available.
