Insecticide use and organophosphate resistance in the coffee leaf miner Leucoptera coffeella (Lepidoptera: Lyonetiidae) [PDF]

Bulletin of Entomological Research, 2002
AbstractIncreasing rates of insecticide use against the coffee leaf miner Leucoptera coffeella (Guérin-Méneville) and field reports on insecticide resistance led to an investigation of the possible occurrence of resistance of this species to some of the oldest insecticides used against it in Brazil: chlorpyrifos, disulfoton, ethion and methyl parathion.

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

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 527-535, June 2026.
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.

New records and new species of Miracinae (Hymenoptera: Braconidae) from Australia and Papua New Guinea, with a key to world Mirax species

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract The genera of Miracinae, currently in something of a state of flux, are discussed with respect to their morphological and molecular attributes. Centistidea Rohwer, 1914 is treated provisionally as a valid genus, distinct from Mirax Haliday, 1833, based partly on propodeal morphology, though this is acknowledged to be an unstable character ...
