Journal of Forest Science, 2002 A new method for evaluating damage caused by tenthredinids to Norway spruce stands is based on defoliation of the top whorls. A scale with four classes of defoliation was established that is easy to use. Defoliation can be displayed graphically on a grid

The predatory behavior of ants: an impressive panoply of morphological adaptations
Insect Science, EarlyView.This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Response of Lowland Rice Plants to Simulated Insect Defoliation in West Africa [PDF]
, 2002 Field experiments were conducted to investigate the impact of simulated insect-caused defoliation on irrigated rice. Defoliation levels tested were 0% (control), 25% defoliation at 21 days after transplanting (dat), 25% defoliation at 41 dat, 25 ...

Insect Science, EarlyView.The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Location and Condition of Whitemarked Tussock Moth (Lepidoptera: Lymantriidae) Cocoons in a Michigan Black Walnut Plantation [PDF]
, 2017 Whitemarked tussock moth, Orgyia leucostigma, cocoons were monitored in a black walnut, Juglans nigra, plantation in Michigan from 1978 to 1981. Larvae spun cocoons on the exposed bark of the bole (29.6070), in crevices on the bole formed by pruning ...

Insect Science, EarlyView.We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.
