- ... The Guatemalan potato moth Tecia solanivora (Povolny) recently invaded part of South America, colonizing zones where Phthorimaea operculella (Zeller), another potato moth species belonging to the same group, was previously established.

- ... In 2006, reports of potential Spodoptera frugiperda resistance to TC1507 maize in Puerto Rico were received. Subsequent investigation confirmed that pest populations collected from several sites in Puerto Rico were largely unaffected by the Cry1F protein in bioassays, with resistance ratios likely in excess of 1000. Since then, we have continued monitoring populations in Puerto Rico and in souther ...
