Multi-pest monitoring on greenhouse tomato

Multi-pest monitoring on greenhouse tomato

Description: This protocol presents sampling and estimation methods to quantify the main pests on tomato in greenhouse.The main pests observed are <i>Trialeurodes vaporariorum</i>, <i>Bemisia tabaci</i> and <i>Tuta absoluta</i> and their natural enemies.

Secondary pests are also studied: leafminer flies (Lyriomyza sp), aphids (Aphys gossypi, Myzus persicae, Macrosiphum euphorbiae, Aulacorthum solani), mites (Tetranychus, Aculops) and the 3 main fungi present on greenhouse tomato: Botrytis cinerea, Leveillula taurica and Oidium neolycopersici.
2 sorts of monitoring are performed:

  • An estimation of the initial state of the pest populations, measured at the moment of the plantation
  • A weekly survey during the 3 first months of the crop, biweekly afterwards.

Use: The method can be used for pest surveys in greenhouse tomato experimentations. It can also help in the elaboration of decision rules in a crop protection context.
