To compare host-searching and ovipositional behavior of Cardiochiles nigriceps Viereck (CN) in tobacco and cotton, behavior of CN females was observed on Hellothis virescens (Febricius)-infested plants and recorded using a Psion Organizer II with Observer software. Hover, search, oviposit, preen, rest, walk, agony-search, drop-search, and miss-search were the nine behaviors observed for each plant species. Agony-search was a searching behavior exhibited when CN females were prevented from… 
Oviposition Behavior of the Wheat Stem Sawfly When Encountering Plants Infested with Cryptic Conspecifics
TLDR
These findings support the use of management tactics relying on the manipulation of oviposition behavior, such as trap cropping, given that there is no evidence for response to previously infested hosts, the infested plants in a trap crop would remain as suitable as they were when uninfested, which could also lead to an increase in mortality caused by intraspecific competition.
Biology of Cardiochiles nigricollis Cameron, a Larval Endo-parasitoid of Cnaphalocrocis medinalis (Guen.) and Marasmia exigua Butler
TLDR
The parasitoid Cardiochiles nigricollis Cameron usually parasitize the fourth instar larvae of Cnaphalocrocis medinalis and Marasmia exigua, but this phenomenon was observed only during wet season and could possibly be due to occurrence of a heterogenous population of C. nigricolls in the field which responded gradually to fall in atmospheric temperature.
The Impact of Herbivore-Induced Plant Volatiles on Parasitoid Foraging Success: A General Deterministic Model
TLDR
A general model is developed to begin examining how timing of volatile release in relationship to host availability for parasitization impacts the utility of these cues to parasitoids and on the extent that this volatile release timing might increase or decrease the percent of herbivores that become parasitized.
Concepts and applications of trap cropping in pest management.
TLDR
A broader definition of trap cropping is proposed that encompasses the inherent characteristics of the trap crop plants themselves as well as the strategies associated with their deployment, which is more knowledge-intensive than many other forms of pest management.
Transmission of Ascovirus from Heliothis virescens (Lepidoptera: Noctuidae) by Three Parasitoids and Effects of Virus on Survival of Parasitoid Cardiochiles nigriceps (Hymenoptera: Braconidae)
TLDR
Observation of C. nigriceps populations in the field indicates this species survives even when ascovirus prevalence in H. virescens is high, and laboratory studies of this host–parasite–virus system showed C.Nigriceps larvae survived infection of their host if parasitoid larvae were at least second instars at the time of infection.

IS ATTRACTION FATAL? THE EFFECTS OF HERBIVORE-INDUCED PLANT VOLATILES ON HERBIVORE PARASITISM
TLDR
The results indicate that differences in parasitoid attraction to herbivore-induced plant volatiles do not contribute to H. subflexa's relatively low parasitism rate.
BEHAVIORAL ADAPTATIONS INCREASE THE VALUE OF ENEMY‐FREE SPACE FOR HELIOTHIS SUBFLEXA, A SPECIALIST HERBIVORE
TLDR
It is found that specialized host‐use and host‐acceptance behaviors are integral to the use of enemy‐free space on Physalis and strongly augment the effects of the structural refuge.
Efficiency of Cardiochiles nigriceps as a Parasite of Heliothis virescens on Cotton
TLDR
A 2-year study of the population density on cotton of a braconid parasite, Cardiochiles nigriceps Viereck, and the corresponding parasitism of Heliothis larvae indicates that 80% Parasitism of H. virescens (F.) on cotton can be achieved with 400–600 C.nigriceps females per acre.
The Ecology of Heliothis Species in Relation to Agroecosystems
TLDR
As key pests of several agricultural and horticultural crops, the four species I have singled out for review have attracted an enormous volume of research work and the literature on their ecology, biology and management is vast.
Parasitic wasps orient to green leaf volatiles
TLDR
The data show that leaf-feeding caterpillars can cause the release of GLVs, and that parasitic wasps can respond to these odors by flying upwind (chemoanemotactic response), which brings the wasps to their caterpillar hosts.
