An Evaluation of Spodoptera littoralis and Spodoptera exigua as Natural Prey for the Generalist Predator Chrysoperla carnea. [PDF]

Insects
Chrysoperla carnea (Stephens) is a common generalist predator in agroecosystems, frequently used for the control of soft-bodied pests in augmentative releases. Better knowledge of its interactions with secondary natural prey is necessary to optimize field biocontrol performance. This work evaluates the eggs and early larvae of Spodoptera exigua (Hübner)

Spodoptera littoralis-Induced Lectin Expression in Tobacco [PDF]

Plant and Cell Physiology, 2009
The induced defense response in plants towards herbivores is mainly regulated by jasmonates and leads to the accumulation of so-called jasmonate-induced proteins. Recently, a jasmonate (JA) inducible lectin called Nicotiana tabacum agglutinin or NICTABA was discovered in tobacco (N. tabacum cv Samsun) leaves.

Influence of overflooding ratios on fruit damage and population growth of Thaumatotibia leucotreta (Meyrick): implications for the sterile insect technique program

Pest Management Science, EarlyView.
Number of infested fruits, larval entries and F1 adults decreased as sterile males increased. Control cages had higher fecundity and fertility compared to treatment cages. Release ratios, 40:1 and 60:1 can enhance the efficacy of SIT. Abstract BACKGROUND Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is a significant pest of citrus in ...

Defining the parameters of comet assay for reliably detecting DNA damage as a marker of X‐ray based irradiation in insects treated with non‐lethal doses for export fruit sanitation

Pest Management Science, EarlyView.
Houseflies, clover root weevils, and mangoes were used to demonstrate the comet assay's adaptability. Our findings indicate that the comet assay can reliably detect irradiation‐induced DNA damage in both insects and fruit. However, the assay parameters require careful adjustment to account for differences in insect tissue types and life stages ...

Prediction of mixture toxicity of essential oil constituents using nonparametric and parametric models against Musca domestica L.

Pest Management Science, EarlyView.
This study evaluated the predictive performance of mixture toxicity models for binary blends of essential oil constituents against Musca domestica. Parametric models (BRAID, Zimmer, MuSyC) outperformed conventional null models by accounting for synergistic or antagonistic interactions, highlighting the need for model selection based on interaction ...
