Chrysomela scripta, Plagiodera versicolora (Coleoptera: Chrysomelidae), and Trichoplusia ni (Lepidoptera: Noctuidae) Track Specific Leaf Developmental Stages

It is well recognized that host-specialized folivores prefer to feed on young in comparison to old leaves. However, the capacity of young leaf feeders to track speciÞc leaf developmental stages has not been clearly demonstrated. Using three insect folivores and two plant species, we show that nitrogen (N) fertilization changes leaf development and that herbivores track these changes in leaf dev...

Evaluation of feeding response,age specific survival and longevity of poplar leafbeetle chrysomela populi (coleoptera chrysomelidae) on five host plants

زیست‌شناسی مقدماتی سوسک برگخوار Chrysomela saliceti Suffrian (Coleoptera: Chrysomelidae)

سوسک‌های برگخوار جنس Chrysomela از آفات مهم نهالستان‌ها و صنوبرکاری‌ها به‌شمار می‌روند. گونۀ Chrysomela populi در بیشتر مناطق صنوبرکاری ایران فعالیت دارد و پژوهش‌هایی هم در مورد آن صورت گرفته‌ است، اما اطلاعات ما در مورد گونه‌های دیگر این جنس بسیار اندک است. زیست‌شناسی گونۀ Chrysomela saliceti با استفاده از حشرات زمستان‌گذرانی کرده در آزمایشگاه (حرارت 1 ± 25 درجۀ سان...

Immature stages of Spodoptera albula (Walker) (Lepidoptera: Noctuidae): developmental parameters and host plants.

This study aimed to detail the temporal and morphological parameters of the immature stages of Spodoptera albula (Walker 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase) and to gather information about their larval host plants. For this purpose, a new rearing method and artificial diet was employed and validated. The viability of the egg, larval, pupal and pre-pu...

Immature Stages of Spodoptera eridania (Lepidoptera: Noctuidae): Developmental Parameters and Host Plants

This study aimed to detail the temporal and morphological parameters of the immature stages of southern armyworm Spodoptera eridania (Stoll, 1782) with larvae feed on artificial diet, under controlled conditions (25 ± 1°C, 70 ± 10% relative humidity and 14-h photophase) and gather information about their larval host plants. The viability of the egg, larval, pupal, and prepupal stages was 97.82,...
