پارامترهای جمعیتی بید گوجه فرنگی Tuta absoluta (Meyrick) (Lep.:Gelechiidae) روی سه گونه‌ی گیاهی تیره‌ی بادمجانیان در شرایط آزمایشگاهی

چکیده بید گوجه فرنگیTuta absoluta (Meyrick)  یکی از آفات کلیدی و خطرناک گیاهان تیره‌ی بادمجانیان به ویژه گوجه‌فرنگی است. این حشره، آفتی محدودخوار است که موطن اصلی آن امریکای جنوبی و کشور پرو می‌باشد. بدلیل اهمیت بالای آفت و خسارت جبران ناپذیر آن روی تیره‌ی بادمجانیان، پارامترهای جمعیتی این حشره روی میزبان‌های گوجه­فرنگی، بادمجان و فلفل با تهیه‎ی جدول زندگی، تعیین گردید. آزمایش‌ها در شرایط دمای...

Neochrysocharis formosa (Westwood) (Hymenoptera: Eulophidae), a newly recorded parasitoid of the tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), in Argentina.

We report the first record of Neochrysocharis formosa (Westwood) parasitizing larvae of the tomato moth, Tuta absoluta (Meyrick), in tomato crops in Northern Buenos Aires Province, Argentina. Tomato moth larvae were sampled during four consecutive growing cycles, between 2003 and 2005, in 10 sites. Neochrysocharis formosa was present only in organic outdoor and protected crops, and predominantl...

Encapsulation and Self-Superparasitism of Pseudapanteles dignus (Muesebeck) (Hymenoptera: Braconidae), a Parasitoid of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)

Endoparasitoids can be killed by host encapsulation, a cellular-mediated host immunological response against parasitism that involves hemocytes aggregation. As a counteracting strategy, many parasitoids can evade this host response through self-superparasitism. The objectives of this study were: 1) to describe the parasitoid Pseudapanteles dignus (Hymenoptera: Braconidae) early immature stages ...

Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae).

Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. Larval developmental time, pupal weight, mean fecundity and an ...
