Weeds: reserves of parasitic phytonematode species populations

Advanced Agritechnologies, 2017
Цель. Анализ отечественных и зарубежных научных источников о роли сорняков как альтернативных хозяев фитонематод семейств Heteroderidae и Meloidogynidae.Результаты. Хозяевами нематод семейства Heteroderidae могут быть 350 видов сорняков из 40 семейств и 155 родов. Более половины из этих сорняков принадлежат к пяти семействам: Маревые Chenopodiaceae (37

The Effects of LED Daylength Extensions on the Daily Activity Patterns of a Greenhouse Biological Control Agent, Aphidius matricariae

Entomologia Experimentalis et Applicata, EarlyView.
We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, EarlyView.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Amendment of Potting Soil With Black Soldier Fly Byproducts Affects Fungus Gnat Development

Entomologia Experimentalis et Applicata, EarlyView.
The study's three experiments were conducted in accordance with the development stages of fungus gnats, with adults emerging from the four treatment substrates and being caught on sticky cards as a common indicator. The treatments were formed from peat‐free potting soil, either pure or supplemented with combinations of byproducts from black soldier fly

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

Entomologia Experimentalis et Applicata, EarlyView.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Laboratory Biology, Immature and Adult Morphology of Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae), Parasitoids of Drosophila Flies

Entomologia Experimentalis et Applicata, EarlyView.
This study investigates the laboratory biology and morphology of the parasitoid Trichopria drosophilae, which targets Drosophila flies, including the invasive Drosophila suzukii. Key findings include a detailed description of the parasitoid's egg, three larval instars, and pupal stage, as well as unique behaviors such as siblicide and encapsulation in ...

The Influence of the Plant Growth Regulator Maleic Hydrazide on Egyptian Broomrape Early Developmental Stages and Its Control Efficacy in Tomato under Greenhouse and Field Conditions

Frontiers in Plant Science, 2017
Broomrapes (Phelipanche spp. and Orobanche spp.) are holoparasitic plants that cause tremendous losses of agricultural crops worldwide. Broomrape control is extremely difficult and only amino acid biosynthesis-inhibiting herbicides present an acceptable ...
