Inheritance of an oviposition behavior by an egg parasitoid [PDF]

Heredity, 2002
A quantitative genetic study revealed genetic and environmental sources of variance in percentage parasitism of European corn borer egg masses and secondary sex ratios by Trichogramma nubilale. Full and half-sib groups of T. nubilale were obtained from a nested mating design, which permitted the partitioning of the variance of T. nubilale parasitism of

First Report of Native Parasitoids of Halyomorpha halys (Hemiptera: Pentatomidae) in Greece

Insects, 2021
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an endemic species of East Asia; it was introduced into Europe in 2007. It has a wide range of hosts as it feeds on over 170 host plant species and significantly impacts crop production. In Greece, H.

What's my age again? Assessing the impact of stink bug egg mass age on host recognition by egg parasitoids <i>Trissolcus basalis</i> and <i>Trissolcus japonicus</i> (Hymenoptera: Scelionidae). [PDF]

Front Physiol
Wasps, from the genus Trissolcus, are egg parasitoids that are commonly used in biological control programs targeting stink bugs. They navigate a complex environment, relying on a diverse array of biochemical and ecological cues to locate their hosts ...

A review of Trichogramma Westwood parasitoids on eggs of Thaumetopoea pityocampa (Denis &amp; Schifferm&uuml;ller) in habitats of the Balkan Peninsula and Asia Minor [PDF]

Silva Balcanica, 2023
Studies on egg parasitoids of the pine processionary moth (Thaumetopoea pityocampa) were conducted during the period 1991-2018 in native localities of the pest on the Balkan Peninsula and in Asia Minor.

Chemical Cues in Tritrophic Interaction on Biocontrol of Insect Pest [PDF]

Journal of Pure and Applied Chemistry Research, 2017
Tritrophic interaction among host plant-herbivore-parasitoid involves chemical cues. The infested plant by herbivores has been reacted to produce volatiles which is a cue used by the herbivore parasitoids for host location.

Egg parasitoids of Thaumetopoea pityocampa in the region of Gyumyurdzhinski Snezhnik in Eastern Rhodopes, Bulgaria [PDF]

Silva Balcanica, 2023
The region of Gyumyurdzhinski Snezhnik in the Eastern Rhodopes is the closest in Bulgaria to the Aegean Sea. However, the climate is characterized by specific parameters that are determined by its relief.

Mechanical interaction of the egg parasitoid Anastatus bifasciatus (Hymenoptera: Eupelmidae) with artificial substrates and its host egg

Frontiers in Mechanical Engineering, 2022
Egg parasitoids play an important role in biological control of pest species attacking and killing their hosts at an early stage of their development. During the antagonistic coevolution with their hosts, egg parasitoids have developed a great ability to

Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]

, 2009
During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...

Life-history traits in closely related secondary parasitoids sharing the same primary parasitoid host: evolutionary opportunities and constraints [PDF]

, 2009
Thus far, few studies have compared life-history traits amongst secondary parasitoids attacking and developing in cocoons of their primary parasitoid hosts.
