Laboratory Biology, Immature and Adult Morphology of Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae), Parasitoids of Drosophila Flies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study investigates the laboratory biology and morphology of the parasitoid Trichopria drosophilae, which targets Drosophila flies, including the invasive Drosophila suzukii. Key findings include a detailed description of the parasitoid's egg, three larval instars, and pupal stage, as well as unique behaviors such as siblicide and encapsulation in ...

The payoffs to agricultural biotechnology: an assessment of the evidence [PDF]

open access: yes
Transgenic crops are relatively new technologies being adopted rapidly in the United States and in a few other countries. The economic impacts of these technologies have, thus far, been estimated in a piecemeal fashion.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

Galleria mellonella (L.) (Pyralidae) und Spodoptera exigua (Hübner) (Noctuidae): Wirkungsunterschiede zwischen XenTari® (Bacillus thuringiensis aizawai), NeemAzal T/S® und ihren Kombinationen [PDF]

open access: yes, 2008
Both, G. mellonella and S. exigua, are most important pests in tropical countries. G. mellonella has five to six generations per year (Abid et al. 1997; Ali 1996), there, and feeding in bee combs they find, besides wax, residues of honey, insect skin and

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

Increased insecticide use in cotton may cause secondary pest outbreaks

open access: yesCalifornia Agriculture, 1976
Pink bollworm, Pectinophora gossy-piella (Saunders), invaded southern California's lower desert valleys during the 1966 cotton growing season. Because of the widespread, damaging infestation levels, multiple applications of broad-spectrum insecticides ...
