Mechanisms of aphid adaptation to host plant resistance
Current Opinion in Insect Science, 2018Host-plant resistant (HPR) crops can play a major role in preventing insect damage, but their durability is limited due to insect adaptation. Research in basal plant resistance provides a framework to investigate adaptation against HPR. Resistance and adaptation are predicted to follow the gene-for-gene and zigzag models of plant defense.

The ecology and evolution of host-plant resistance to insects
Trends in Ecology & Evolution, 1990Genetic techniques have yielded new insights into plant-herbivore coevolution. Quantitative genetic tests of herbivory theory reveal that in some cases insect herbivores impose selection on resistance traits. Also, some resistance traits are costly while others appear not to be, and genetic models can explain these results.

Host Plant Resistance Breeding
2019Biotic stresses are the damage to plants caused by other living organisms such as bacteria, fungi, nematodes, insects, viruses and viroids. Some of the biotic stresses that devastated the world in the past are the potato blight in Ireland, coffee rust in Brazil, maize leaf blight in the USA.

HOST-PLANT RESISTANCE IN PEST MANAGEMENT
Tropical Agrobiodiversity, 2021Host Plant Resistance (HPR) is an effective, economical and eco-friendly method introduced for pest management. The concept of HPR has been emphasized mainly in order to reduce the use of pesticides as it provides opportunities to improve research and extension documentation to assist producers. It can also be taken as an effective tool for sustainable

Biotechnological Interventions in Host Plant Resistance
2009abstract Host plant resistance forms an integral part of integrated pest management. Conventional host plant resistance is slow and difficult to achieve due to the involvement of quantitative traits at several loci. However, recent biotechnological interventions have opened up new opportunities for pest control by providing an access to novel molecules,

Insect Biotypes and Host Plant Resistance
2017The green plants and herbivorous insects are engaged in a constant struggle for dominance. Humans usually intervene in this struggle by developing pest-resistant genotypes and other pest management tactics. Upon failure of a previously successful tactic to which the insect population has apparently adapted, the latter is often considered to be a novel ...

Genetics of Pathogenicity in Viruses and of Resistance in Host Plants
1965Publisher Summary In nature, viruses and their host plants are constantly subjected to selective competition. Selection among viruses tends to raise or lower their degrees of pathogencity, such as to reach the most favorable level for their action in each host. Selection among host plants gradually increases the levels of resistance in all the hosts.

Insect Behaviour and Host Plant Resistance
International Journal of Tropical Insect Science, 1985This paper discusses insect behaviour and host plant resistance under single-plant species resistance and plant population resistance. Under single-plant species resistance, the effects of repellents, surface texture, shape and colour to insect behaviour are briefly reviewed and discussed.
