“…Low light is a stress to plants and can enhance the effect of defoliation damage on perennial species, including causing plant death if both the light and defoliation stress is severe (Baraza et al, 2004;Blundell and Peart, 2001;Lentz and Cipollini, 1998;Norghauer et al, 2008). Lockett et al (2012) observed a significant impact of Chiasmia assimilis (Warren) (Geometridae) on seedlings of prickly acacia [Acacia nilotica (L.) Delile subsp. indica (Benth.)…”

“…For example, defoliation can have a more severe effect on shaded plants relative to unshaded plants or on species that may be less shade tolerant (Baraza et al, 2004;Blundell and Peart, 2001; Lentz and Cipollini, 1998;Norghauer et al, 2008;Rogers and Siemann, 2003). Assessing the impact of candidate agents under a variety of environmental conditions and on different life stages of the target weed can aid our understanding of potential outcomes of weed biological control programs (Berg et al, 2015;Lockett et al, 2012). of ambient light in forest interiors and up to 34% of ambient light at forest edges (Averill, 2009;Milbrath, 2008).…”

Alien plants are invading protected areas worldwide, but there is little information from tropical Asia. Java has the longest record of human occupation in Asia and today supports 145 m people. Remnants of natural ecosystems survive in 12 small National Parks surrounded by dense human populations, making them highly vulnerable to invasions. We surveyed eight of these, along a rainfall gradient from lowland rainforest with >3000 mm annual rainfall to savanna with <1500 mm, and a 0–3158 m altitudinal gradient, using 403 10 × 5 m plots along trails. We found 67 invasive alien plant species, of which 33 occurred in only one park and two (Chromolaena odorata and Lantana camara) in all. Historical factors relating to plant introduction appeared to be as important as environmental factors in determining which species occurred in which park, while within parks canopy cover and altitude were generally most influential. Spread away from trails was only evident in open habitats, including natural savannas in Baluran National Park, threatened by invasion of Acacia nilotica. Existing control attempts for invasive aliens are reactive, localized, and intermittent, and insufficient resources are currently available for the early detection, prompt action, and continued monitoring that are needed.

“…A number of studies have reported that shading enhances the performance of weed biological control agents. For example, Lockett et al 38 recorded significant herbivory by a leaf-feeding geometrid, Chiasmiaassimilis (Warren) (Lepidoptera: Geometridae), on shaded Acacianilotica subsp. indica (Bentham) Brenan (Fabaceae).…”

Unravelling the responses of insect herbivores to light-environment-mediated variation in the traits of their host plants is central to our understanding of the nutritional ecology of, and factors driving the population dynamics in, these species. This study examined the effect of light environment (shaded vs full-sun habitat) on leaf toughness and leaf nutritional quality in Chromolaena odorata (an invasive species in West Africa) and related these attributes to the abundance, herbivory patterns and reproductive performance of a multivoltine specialist moth, Pareuchaetes pseudoinsulata (a biological control agent). In this system, plants growing in shaded areas in the field experienced more herbivory and had higher herbivore abundance than those growing in full-sun. In the laboratory, P. pseudoinsulata larvae consumed significantly greater amounts of shaded foliage relative to full-sun foliage. However, reproductive performance metrics such as mating success, pre-oviposition period, number of eggs laid, duration of egg laying, egg hatchability, and adult longevity in P. pseudoinsulata did not differ according to foliage types. Reduced leaf toughness, increased water and nitrogen contents in shaded leaves coincided with increased leaf consumption by the larvae of P. pseudoinsulata. In summary, this study showed for the first time that light environments affect herbivory patterns but not reproductive performance of P. pseudoinsulata and hypothesized that high foliar nitrogen and water contents in shaded leaves resulted in feedback and necessity consumption patterns.
