Baseline Susceptibility of the Field Populations of in Indonesia to the Proteins Cry1A.105 and Cry2Ab2 of .

Genetically modified MON 89034 corn ( L.) expressing () insecticidal proteins, viz. Cry1A.

Complex multiple introductions drive fall armyworm invasions into Asia and Australia.

The fall armyworm (FAW) Spodoptera frugiperda is thought to have undergone a rapid 'west-to-east' spread since 2016 when it was first identified in western Africa. Between 2018 and 2020, it was recorded from South Asia (SA), Southeast Asia (SEA), East Asia (EA), and Pacific/Australia (PA). Population genomic analyses enabled the understanding of pathways, population sources, and gene flow in this notorious agricultural pest species.

Inheritance and Realized Heritability of Resistance to Imidacloprid in the Brown Planthopper, Nilaparvata lugens (Hemiptera: Delphacidae), From Indonesia.

The brown planthopper, Nilaparvata lugens Stål., is a major insect pest causing serious damage to the rice crop in many rice-producing countries. The aim of the study was to determine the inheritance characteristics and realized heritability of resistance to imidacloprid in N.

Susceptibility of field-collected populations of the southwestern corn borer, Diatraea grandiosella, to Bacillus thuringiensis.

The susceptibilitity of newly hatched larvae of laboratory-adapted and field-collected populations of the Southwestern corn borer, Diatraea grandiosella (Dyar) (Lepidoptera: Crambidae), to a Bacillus thuringiensis protein (Cry1Ab) was examined using a larval feeding bioassay. D grandiosella populations were collected from five states: Missouri, Kansas, Texas, Tennessee and Kentucky. Using larval mortality as the end-point of the bioassay, the magnitude of differences in the susceptibility of the laboratory-adapted and the field-collected populations to Cry1Ab protein varied from one to 46 times depending on the time of observation and the standard of comparison (LC50 or LC95).
