Stage-specific predation and functional response of Orius insidiosus (Hemiptera: Anthocoridae) toward Diaphorina citri (Hemiptera: Psyllidae) and differential toxicity of formulated pesticide mixtures.

Stage-dependent predation by Euagoras plagiatus against Spodoptera frugiperda and Helicoverpa armigera larvae under laboratory conditions.

BACKGROUND Spodoptera frugiperda and Helicoverpa armigera are destructive noctuid pests resistant to multiple pesticides. This study quantified predatory performance, functional response, searching efficiency, and prey preference across developmental stages of Euagoras plagiatus against second-instar larvae of both pes...

Biological parameters of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) exposed to deltamethrin

Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) is a biological control agent whose efficacy may be affected by insecticides. The effects of Decis 25 EC® (deltamethrin) were evaluated through the provision of treated pupae of Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae) on the mortality, longevity, and...

Host age-mediated effects on fitness traits of five Anastatus parasitoids: Implications for optimizing biological control of Riptortus pedestris.

Overall, A. dexingensis and A. japonicus appear well suited for short-term suppression of R. pedestris through inundative releases, whereas the thelytokous A. gansuensis shows strong potential for long-term, sustainable population regulation, making it promising for augmentative biocontrol.

Population growth and predation efficiency of three phytoseiid species fed Panonychus ulmi in Egypt

The European red mite, Panonychus ulmi (Koch), is one of the most serious pests affecting apple orchards globally, with increasing cases of resistance to conventional chemical compounds. Despite its importance, little is known about the potential of the locally Egyptian predatory mites as biological control agents agai...

Predatory potential of Ceraeochrysa cubana (Hagen) (Neuroptera: Chrysopidae) against Raoiella indica Hirst (Acari: Tenuipalpidae)

The red palm mite, Raoiella indica Hirst (Acari: Tenuipalpidae), is an important pest of coconut plantations in tropical countries. Ecologically sound control strategies have been sought for this pest; however, biological control using native green lacewings against R. indica remains poorly investigated. The present st...

Bottom-up effects of strawberry cultivar resistance on the demographic and predatory performance of Neoseiulus californicus (Phytoseiidae) against Phytonemus pallidus (Tarsonemidae)
