Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

open access: yesPest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Effect of photoperiod on parasitization by Trichogramma principium (Hymenoptera: Trichogrammatidae)

open access: yesEuropean Journal of Entomology, 2007
The effect of photoperiod on parasitization of the eggs of the Angoumois grain moth, Sitotroga cerealella (Olivier, 1789) by Trichogramma principium Sugonyaev & Sorokina, 1976 was investigated under several photoperiodic regimes of L : D = 3 : 21, 6 : 18,

Evaluating predatory arthropods for the biological control of the invasive Thrips parvispinus (Thysanoptera: Thripidae) in greenhouse sweet pepper

open access: yesPest Management Science, EarlyView.
This study shows that Orius laevigatus, alone or with other predators, consistently achieved the highest suppression of Thrips parvispinus and improved plant productivity. Franklinothrips vespiformis coexisted with O. laevigatus, suggesting compatibility, while Amblyseius swirskii declined, indicating incompatibility. Individually, F. vespiformis and A.

Dietary restriction induces persistent multigenerational phenotypic effects in Phytoseiulus persimilis

open access: yesPest Management Science, EarlyView.
The study shows ancestral dietary restriction in Phytoseiulus persimilis produces persistent, sex‐specific, multi‐generational effects on survival and body size, with stronger maternal than paternal lineage influences despite nutritional recovery. Abstract BACKGROUND Transgenerational phenotypic plasticity (TGP) allows environmental effects to persist ...

Behavioral responses of adult female tobacco hornworms, Manduca sexta, to hostplant volatiles change with age and mating status

open access: yesJournal of Insect Science, 2002
We present evidence for two behaviors influenced by intact, vegetative plant odor -- upwind flight and abdomen curling -- in female Manduca sexta and demonstrate the influence of the age and mating status of the moths on these behaviors.

Electrophysiological Responses and Reproductive Behavior of Fall Webworm Moths (Hyphantria cunea Drury) are Influenced by Volatile Compounds from Its Mulberry Host (Morus alba L.)

open access: yesInsects, 2016
Hyphantria cunea (Drury) is an invasive pest of Morus alba L. in China. β-ocimene and cis-2-penten-1-ol among eleven electro-physiologically active leaf volatiles from M.

Is oviposition time and oviposition interval associated with the deposition of cuticle on the hen’s egg?

open access: yesBritish Poultry Science
1. The cuticle acts as a barrier to prevent microbial penetration of the eggshell. The reduction in the oviposition interval with selection for egg production and the activity of clock genes in the oviduct led to testing the hypothesis that the interval between successive oviposition of eggs would be related to the deposition of the cuticle. 2.

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

open access: yesPest Management Science, EarlyView.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.

Oviposition of the invasive two-spotted leafhopper on an endemic tree: Effects of an alien weed, foliar pubescence, and habitat humidity

open access: yesJournal of Insect Science, 2004
The two-spotted leafhopper, Sophonia rufofascia (Kuoh and Kuoh), is an exotic pest from South-East Asia that attacks a wide variety of plant species in Hawaii.
