The field incidence of the serpentine leaf miner, L. trifolii(Burgess) was severe during the fruiting stage of the crop and infestation was higher on lower surface of leaf in comparisons of upper surface. On the basis of cumulative susceptibility index test varieties viz. HS-102, SEL-14, Pant T-4, PS-8, PT-28, NDT-44, BT-117-5-3-1, Pusa Ruby (Check), KS-118, Pant Bahar, CO-3, Pant Hybrid-1, BBs...

The tomato leafminer, Tuta absoluta causing a huge economic problem in Egypt. effects of Agree 50% WG, Avaunt 15% EC, Excellent 1.9% Titan, Castor aqueous extract, K.Z oil, and Alboleum oil against the leaf- miner, T. (Meyrick) were evaluated. EC is succeeded management since it initially reduced infestation 80.42 78.29, respectively. Meanwhile, total mean reduction after 1, 3, 10, 15 days 79.2...

the tomato leafminer, tuta absoluta (meyrick), is one of the most important pests of tomato, solanum lycopersicum l., in iran. in this research, natural enemies diversity of t. absoluta and proportion of predators or parasitoids density to moth eggs or larvae density on five tomato cultivars including super strain b, super chief, mobil, korral, and early urbana y were studied in an experimental...

Shaded coffee agroecosystems traditionally have few pest problems potentially due to higher abundance and diversity of predators of herbivores. However, with coffee intensification (e.g., shade tree removal or pruning), some pest problems increase. For example, coffee leaf miner outbreaks have been linked to more intensive management and increased use of agrochemicals. Parasitic wasps control t...

A major challenge in network ecology is to describe the full-range of species interactions in a community to create highly-resolved food-webs. We developed a molecular approach based on DNA full barcoding and mini-barcoding to describe difficult to observe plant-leaf miner-parasitoid interactions, consisting of animals commonly regarded as agricultural pests and their natural enemies. We tested...

From the perspective of a specialist herbivore, how homogenous are individual tree crowns as patches of habitat? We partitioned variation in physical and chemical host leaf traits and in the abundance and performance of a specialist oak leaf miner, Tischeria ekebladella , into variation at different hierarchical levels. For the phenolic contents of the leaves, we examined variation among oak st...
