Abstract

Simulated windrow experiments revealed that 32.0 ± 8.4% or 3rd-instar Agromyza frontella (Rondani) larvae completed development and formed puparia in alfalfa hay during field curing; 1st- and 2nd-instar larvae suffered almost complete mortality. Under a management schedule where first harvest was at 10% bloom, adult emergence was 45% higher from soil under windrowed hay than from soil under strips immediately raked. Development of A. frontella in hay being field-cured is discussed in relation to crop pest management and crop management options.

Résumé

Lors d'expériences d'andainage simulé, 32.0 ± 8.4% des larves de 3ième stade de la mineuse Agromyza frontella (Rondani) ou complété leur développement et formé le puparium à partir de foin en séchage sur le champ; les larves des 1er et 2ième stades sont mortes en grande majorité. Dans un programme de coupe où la première récolte fut effectuée à 10% de floraison, l'émergence des adultes à partir du sol sous le foin andainé s'est avérée de 45% supérieure à celle à partir des bandes de sol immédiatement dénudées. Le développement d'A. frontella dans le foin en séchage sur le champ est considéré en rapport avec la lutte intégrée et les différentes options culturales.
