Timing of Surveys<br />
Tuta absoluta is a multivoltine species (EPPO, 2005; Vargas, 1970). Given its<br />
biology, greenhouse surveys for T. absoluta should be conducted year-round,<br />
because environmental conditions inside these structures would allow<br />
continuous and overlapping generations to develop. Surveys in field grown<br />
host plants should begin as soon as seedlings are well-established. Times of the<br />
year will vary depending on geographical location.<br />
