feeding and oviposition preference of Helopeltis theivora （Hemiptera： Miridae） on tea in Northeast India

Insect Science 2006年第6期13卷 485-488页

作者： MANTU BHUYAN PRANAB R. BHATTACHARYYA Division of Plant Sciences and Ecology Regional Research Laboratory Jorhat. Assam India

feeding and oviposition preference studies of Helopeltis theivora Waterhouse, on leaves and stems of tea, Camellia sinensis L.（O）Kuntze, revealed that the insect mostly preferred the second leaf for feeding in comparison to the first, and the third leaf and stems; while the fifth instar nymphs were the most voracious feeders among the life stages, producing themost and largest feeding lesions. The insect preferred to oviposit mainly on stems and very few eggs are found on leaves.

Host preferences pine of the sawyer beetle, Monochamus alternates (Hope), during maturation feeding on 8 conifer trees and 40 masson pine provenances, were investigated using 3 types of laboratory bioassay of consistent feeding preference, feeding area and visitation frequency. M. alternatus adults have the highest frequency of feeding and prefer to feed on the branches of P. massoniana and P. densiflora and had significant host selectivity on 8 conifer trees in the area of Nanjing. The adult feeding vi...

preference of the Herbivorous Marine Teleost Siganus canaliculatus for Different Macroalgae

引用

Journal of Ocean University of China 2014年第3期13卷 516-522页

作者： YOU Cuihong ZENG Fangui WANG Shuqi LI Yuanyou Marine Biology Institute of Shantou University Guangdong Provincial Key Laboratory of Marine Biotechnology

The decomposition of a large amount of unexploited macroalgal resource along the coast of China often results in heavy environmental pollution. In order to pave a way of using macroalgae as the dietary ingredient of rabbitfish Siganus canaliculatus, one of a few farmed herbivorous marine teleosts in China, its preference(feeding selectivity) for different macroalgae was determined in this study. Seven seaweed species abundantly inhabiting the coast of east Guangdong Province were exposed simultaneously to rabbitfish juveniles in laboratory(multiple-choice feeding) with their content and absolute intake assayed. It was found that the most preferred algae were Ulva prolifera, Gracilaria lemaneiformis and Chaetomorpha linum, less preferred algae were U. pertusa and Porphyra haitanensis, and least preferred ones were Sargassum fusiforme and Corallina sessilis. Such an order did not change when one to four relatively preferred seaweeds were removed. The preferred seaweeds were richer in protein and soluble sugar thus higher in energy than the least preferred. In addition, this fish was found to favor filamentous and flat algae rather than calcified ones. Accordingly, the richness of nutrients and morphological characteristics determined the preference of S. canaliculatus for tested macroalgae.
