1. 1. Effect of Touch on Cotton and Maize : influence on plant morphology and feeding preference in Spodoptera littoralis

   University essay from SLU/Dept. of Plant Protection Biology

   Author : Anna Magnusson; [2022]
   Keywords : Mechanical stimuli; cotton; maize; thigmomorphogenesis; Spodoptera littoralis; induced defence; plant-plant interaction;

   Abstract : Plants are constantly exposed to touch and mechanical stimuli in natural environments, from rain, wind, animals and plant neighbours. However, current knowledge and understanding of how touch physiologically affects plants are limited. READ MORE

3. 2. Can alteration in host odor blends change the olfactory preferences in Spodoptera littoralis?

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Hanna Olovsson; [2017]
   Keywords : host preference; Spodoptera littoralis; induction of feeding; cotton; olfactometer; y-tube;

   Abstract : Gustatory and olfactory stimuli have been shown to induce feeding preferences in generalist phytophagous insect species. Generalists have to process a lot of information while performing host selection and it has been suggested that this may be a limitation, while it makes the host detection slower than for specialist species that process a lower amount of information.

4. 3. The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Joakim Sjöstrand; [2014]
   Keywords : Spodoptera littoralis; Agriotes lineatus; insect resistance; cotton; gossypium;

   Abstract : A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.

5. 4. Feeding preferences and foraging in Larvae of Manduca sexta and Spodoptera littoralis : a laboratory study based on olfaction

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Elin Nyström; [2013]
   Keywords : Manduca sexta; Spodoptera littoralis; larvae; foraging; olfaction; larval dual choice test; induced feeding preference;

   Abstract : Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. READ MORE

6. 5. Olfactory response in caterpillars of Pieris rapae for host recognition

   University essay from SLU/Dept. of Ecology

   Author : Tomas Schön; [2011]
   Keywords : Pieris rapae; Brassicaceae; glucosinolate; volatiles; feeding preferences; food choice; caterpillar;

   Abstract : Plants interact with phytophagus insects through release of volatile chemical compounds. They can either function as a defense against herbivores by attracting predators and parasitoids, or they can act as an attractant for the herbivores themselves. READ MORE
