Evaluation of bio-rational insecticides to control Helicoverpa armigera (Hübner) and Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) fed on Vicia faba L. [PDF]

open access: yes, 2008
Two botanical pesticides, Neem Azal-T/S (NA) and Quassia amara, one biopesticide, Bacillus thuringiensis subsp. aizawai (Bta) and one combination of Bta + NA were tested against 2nd and 4th instar larvae of the noctuids Helicoverpa armigera (Hübner) and ...

The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

The Toxicity and Biochemical Activity of Spinosad, Emamectin Benzoate and Dinotefuran on Spodoptera littoralis (Boisd.) [PDF]

open access: yesJournal of Plant Protection and Pathology
The failure of the traditional insecticides to control cotton leafworm Spodoptera littoralis led to severe losses in different crops as a result of resistance development.

Laboratory Studies on Spinosyns Compounds Against Different Pests [PDF]

open access: yesAcarines: Journal of the Egyptian Society of Acarology, 2009
Spinosyns are new neurotoxins mixtures produced during fermentation of a soil actinomycete that have high activitytowards different pests. Spinosyns compounds were represented in Spinosad and its evoluted compound ,Spinetoram,which were tested for their ...

EFFECTS OF CERTAIN INSECTICIDES ON EGGS OF SPODOPTERA LITTORALIS [PDF]

open access: yesEgyptian Journal of Agricultural Research, 2014
Seven chemical insecticides were tested for their ovicidal activity against Spodoptera littoralis eggs, using two methods, namely dipping of tafla leaves containing 0-1 day old eggs and o-day old eggs were deposited on insecticide residues on tafla leaves. Rynaxypyr was the most promising. It was taken as the standard insecticide and given an arbitrary

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

open access: yesEcological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Paving the Way for Plant‐Based Bioproduction of (Z)‐13‐Octadecenoic Moth Pheromone Compounds

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sex pheromones are eco‐friendly agents to control pest insects. Yet, the cost of synthetic pheromone production has restricted their use essentially to high value crops. Plant‐based bioproduction of pheromone compounds offers a promising and sustainable alternative, opening up for the deployment of pheromone‐mediated pest control also in row ...

Antifeedant Activity Evaluation of Withanolides from Jaborosa integrifolia

open access: yesMolecules, 2000
Antifeedant activity of the 4-deoxi-27-hydroxi-withanolides (1, 2 y 3) isolated from Jaborosa integrifolia (Solanaceae) was investigated in caterpillar Spodoptera littoralis on Leaf Disk Choice Bioassay.

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...
