“…Tomato, Solanum lycopersicum L. (Solanaceae), production is damaged by the leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), which is considered as one of the most important pests in both greenhouse and outdoor production (Desneux et al 2010;Desneux et al 2011;Campos et al 2017). Native to South America, this Microlepidoptera has recently become an invasive pest on tomato crops in Europe (Desneux et al 2011) and Africa (Brévault et al 2014;Tonnang et al 2015).…”

The leafminer Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most important pests of tomato, reducing crop yields by up to 100% in greenhouses and fields, in several countries globally. Because synthetic insecticides lead to resistance and have adverse effects on natural enemies and the health of producers, alternative control methods are needed. In this study, we assessed the oviposition-deterring effect of basil plants, Ocimum gratissimum L. and O. basilicum L. (Lamiaceae), using dual-choice behavioural assays performed in flight tunnels. We found that both plants significantly reduced T. absoluta oviposition behaviour on a tomato plant located nearby. To evaluate the potential effect of basil volatile organic compounds, we formulated essential oils of both plant species in paraffin oil, and observed a similar oviposition-deterring effect. Gas chromatography analyses detected 18 constituents in these essential oils which the major constituents included thymol (33.3%), p-cymene (20.4%), γ-terpinene (16.9%), myrcene (3.9%) in O. gratissimum and estragol (73.8%), linalool (8.6%), β-elemene (2.9%) and E-β-ocimene (2.6%) in O. basilicum. Twenty and 33 compounds were identified of the volatiles collected on O. gratissimum and O. basilicum plants, respectively. The main components include the following: p-cymene (33.5%), γ-terpinene (23.6%), α-terpinene (7.2%), α-thujene (6.7%) and E-α-bergamotene (38.9%) in O. gratissimum, and methyl eugenol (26.1%), E-β-ocimene (17.7%), and linalool (9.4%) in O. basilicum. Four compounds (α-pinene, β-pinene, Myrcene, Limonene) were common in essential oils and plants. Our results suggest the valuable potential of basil and associated essential oils as a component of integrated management strategies against the tomato leafminer.

“…Native to South America, this Microlepidoptera has recently become an invasive pest on tomato crops in Europe (Desneux et al 2011) and Africa (Brévault et al 2014;Tonnang et al 2015). Tuta absoluta larvae destroy all aerial parts of plants (leaves, stems, fruits, buds and flowers), resulting in severe yield losses (i.e.…”

SummaryIn this study, the resistance of two (Aydın and Urla) populations of T. absoluta against five commonly used insecticides (indoxacarb, spinosad, azadirachtin, chlorantraniliprole and metaflumizone) were determined. Further, the activity of insecticide detoxifying enzymes [gluthation-S-transferase (GST) and esterase (EST)] was also evaluated to confirm the resistance. Aydın population of T. absoluta had higher resistant values 8-fold, 3.79-fold, 6.4-fold and 1.84-fold for indoxacarb, metaflumizone, spinosad and chlorantraniliprole, respectively against all insecticides except azadirachtin compared to the Urla population. It was determined that in comparison with T.absoluta population from Aydın, the Urla population can be more susceptible to other insecticides except azadirachtin. GST enzyme activity was 1.5-fold higher in Aydın than the Urla populations, however, EST enzyme had similar activity in both the populations. The results of study imply that T. absoluta populations from Aydın (Turkey) can be resistant against indoxacarb, metaflumizone, spinosad and chlorantraniliprole. Increased GST enzyme activity in resistant populations confirms this resistance development. Insecticides of plant origin like azadirachtin, for which least insecticide resistance was recorded, may be applied in combination with other methods to effectively control T.absoluta. Keywords: Tuta absoluta, resistance, enzymes, leaf dip ÖzetBu çalışmada T. absoluta'nın iki populasyonunun (Aydın ve Urla) en çok kullanılan 5 insektisite karşı (indoxacarb, spinosad, azadirachtin, chlorantraniliprol ve metaflumizon) direnç durumları tespit edilmiştir. Ayrıca detoksifikasyon enzimlerinin [glutation-S-transferaz (GST) ve esteraz (EST)] aktiviteleri de direnci doğrulamak için saptanmıştır. T.absoluta Aydın populasyonunun azadirachtin hariç diğer insektisitlere karşı (Urla populasyonuna göre) sırasıyla indoxacarb, metaflumizon, spinosad ve chlorantaraniliprol'e karşı 8, 3.79, 6.4 ve 1.84 kat direnç geliştirdiği gözlenmiştir. Aydın populasyonu ile karşılaştırıldığında Urla populasyonunun azadirachtin hariç diğer insektisitlere karşı daha duyarlı olabileceği saptanmıştır. GST enzim aktivitesi Urla populasyonuna göre Aydın populasyonunda 1.5-kat fazla iken, EST enzimi için her iki populasyonda benzer sonuçlar bulunmuştur. Çalışmanın sonuçları, Aydın (Türkiye)'dan alınan bir T. absoluta populasyonunun indoxacarb, metaflumizon, spinosad ve chlorantraniliprol'e karşı dirençli olabileceğine işaret etmektedir. Dirençli populasyondaki artan GST enzim aktivitesi, bu direnç gelişimini doğrulamaktadır. En az insektisit direnci rapor edilmiş olan bitkisel kaynaklı insektisit azadirachtin diğer metodlarla birlikte bu zararlının etkili bir şekilde kontrol edilmesinde uygulanabilir.

“…Then, it was detected in several European and North-African countries, mainly in Mediterranean region [5] . At the present time, it is quickly propagated apart from the Mediterranean region [7] . Most damage are concentrated in the apical and median parts of plants it is able to cause up to 80% or 100% of losses [8,6] .…”

In the Tunisian south, the heated greenhouses are an important axis of development of agriculture thanks to the big geothermal potential of this zone. Currently, this sector suffers from several phytosanitary problems. In the last years, a new insect, Tuta absoluta, threaten the cultures of cultivated tomatoes in heated greenhouses. To improve control of T. absoluta, the effectiveness of pheromone traps (associated or not with a source of light) and luminous traps (associated or not with water, with limed buckets for limed covers) were compared. The results show that the traps with pheromones significantly catch more adults of T. absoluta compared to all the other types of traps (average number of trapped adults of T. absoluta = 73.4 (± 142)). The luminous traps associated with water, with limed buckets as with limed covers show, as for them, an intermediate effectiveness. In spite of this slightly less effectiveness, the luminous traps have the advantage of low costs of production as well as the advantage of simultaneously capturing males and females of T. absoluta.
