Book Description
Organisms do not exist in complete isolation, they all interact with one another. These interactions can come from predators, parasites, competitors, and even mutualists. Here I test the hypothesis that pollination behaviors thought to expend more energy, may in fact be beneficial to the pollinator in terms of provisioning more resources for their progeny, as well as host plant. My study system is the obligate mutualism between two species of Joshua tree (Yucca brevifolia and Yucca jaegeriana) and their associated moth pollinators (Tegeticula synthetica and Tegeticula antithetica). I reconstructed sibships among pollinator larvae using DNA barcoding and microsatellite genotyping to infer instances in which female yucca moths had likely cross pollinated. I show that fruit seed and larvae totals were not significantly different between fruits that were a result of cross pollination and those that were not. I used regression modeling to see if the number of pollinator larvae influenced the number of seeds after accounting for climate variables. Here I saw a significant negative impact on seed totals, but also a strong effect from co-occurring seed predators. Other factors are likely to play a role in pollinators' return on investments which were unable to be incorporated for this study. These results are consistent with other studies demonstrating that moth interests are not in alignment with their host plant.

Book Description
Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The text also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant Stress-Insect Interactions Edited by E. A. Heinrichs "This is a far-reaching, seminal book that summarizes our understanding of the complexity of real-world ecology." —Choice This first major overview of the various abiotic and biotic stresses on plants outlines in detail what impact their responses have on their suitability as insect hosts. The effects of abiotic stress are catalogued in up-to-date research from leading specialists. The implications of plant stress on global food production in this era of diminishing croplands and rising populations is described, as well as avenues for the development of tolerant crop cultivars. 1988 (0 471-82648-0) 492 pp. Plant Resistance to Insects A Fundamental Approach C. Michael Smith This comprehensive text—developed out of the author’s vast field and academic experience—describes how biological and agricultural scientists identify and develop plant materials resistant to insects. Covers terminology and categories of resistance; investigative techniques for studying plant resistance; and crop management systems that use insect-resistant cultivars. Supplemented with tables detailing types and numbers of insect-resistant plant cultivars in the U.S. and formulae on quantifying plant tolerance of insects. 1989 (0 471-84938-3) 286 pp.
