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 />
