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.

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.

Evidence of Cuticle Chemicals of Heortia vitessoides (Lepidoptera: Crambidae) Larvae Influencing the Aggregation Behavior of Conspecific Larvae

open access: yesInsects
Heortia vitessoides (Lepidoptera: Crambidae) is a severe pest of Aquilaria plants, which produce high-priced agarwood. The larval stage of this pest is gregarious, usually forming large aggregates during young instars and becoming solitary during the ...

Study of some biological aspects of the blowfly Chrysomya albiceps (Wiedemann 1819) (Diptera: Calliphoridae) in Jeddah, Saudi Arabia

open access: yesEgyptian Journal of Forensic Sciences, 2016
We reared Chrysomya albiceps (Wiedemann 1819) unadult stages (first larval instar, second larval instar, third larval instar and pupal stage) under four constant temperatures. Results proved that increasing temperature from 20 to 25, 30 and 35 °C reduced

External morphology of the first and second instars of Lecanodiaspis tingtunensis (Coccoidea: Lecanodiaspididae) [PDF]

open access: yes, 2003
The first and second instars of Lecanodiaspis tingtunensis are described and illustrated. First instars are distinguished from other species of Lecanodiaspis by the arrangement of dorsal 8-shaped pores in six complete longitudinal rows and a partial row ...

Bt agave: why it is time to explore a new biotechnological frontier

open access: yesPest Management Science, EarlyView.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.
