“…Based on the results of the laboratory tests, 10 cm pieces would be the most adequate size for this because they attracted the greatest mass recruitment. However, more studies are needed to support these hypotheses, since in addition to foraging behavior inherent to the species, other factors might interfere with termite foraging, such as edaphoclimatic conditions, presence of other food sources and predators, soil structure and humidity, and level of soil disturbance (Hu & Appel, 2004;Souza et al, 2009;Santos et al, 2010;Dow AgroSciences, 2013).…”

Influence of Food Resource Size on the Foraging Behavior of Nasutitermes corniger (Motschulsky)

et al. 2018

In general, termite foraging can be affected by physical and chemical factors linked to food. This study investigated if the wood length of Eucalyptus grandis W. Hill ex Maiden, as a food resource, influences the behavior of foraging events of Nasutitermes corniger (Motschulsky). Nests with mature and active colonies were collected in the field and transferred to glass cubes connected to a test arena under laboratory conditions. Wooden blocks of E. grandis, with a 2.5 x 2.0 cm rectangular cross section, were offered to termites in three different lengths: 5, 10 and 15 cm. Each test was repeated with 20 nests and lasted 60 minutes, when the following behavioral events and their duration were observed: initial exploration, initial recruitment and mass recruitment. At the end of each test, the quantities of termites (total, workers and soldiers) and gnawing workers were determined. The results show that longer blocks favored a higher occurrence of exploration and initial recruitment. However, the highest mass recruitment occurred with the 10 cm blocks. The length of the wood influenced the total number of termites recruited and gnawing workers; both were highest for the 10 cm blocks. There was no significant difference in relation to exploration time of the blocks and number of workers and soldiers recruited. Therefore, we conclude that wood length is a factor that can affect N. corniger foraging.

“…However, given the long time since their construction (>200 years), the quality of the wood had deteriorated due to environmental factors. Basidiomycete fungi can change the wood’s physical–mechanical properties and reduce the durability of wooden materials [ 48 ] that are preferred by termites [ 22 ]. Fungal mycelium can trigger and accelerate termite activity and consequently increase the level of wood destruction [ 4 , 49 ].…”

“…The timber and construction industries are suspected to be the most effective media for the spread of C. gestroi in Indonesia. Even though wood preservation methodsagainst C. gestroi are well developed [ 21 , 22 ], economic loss caused by this species is increasing in Southeast Asia [ 21 ], and Coptotermes spp. are known to be serious pests, attacking buildings in China [ 23 ], Malaysia [ 24 ], and Indonesia [ 25 ].…”

Surveys of the conditions of termite attack were conducted in two regencies, Pidie and Greater Aceh, Aceh Province, Indonesia (40 houses in each location). Interviews were also conducted with home owners to collect data on the building history; culture, such as daily life in the house; the frequency and intensity of termite attacks; and traditional knowledge for avoiding and/or suppressing termite attacks. We found that 51% of traditional houses were infested by two termite species: Coptotermes gestroi and Nasutitermes matangensis. The lower parts of traditional houses were frequently attacked and severely damaged by termites. Previous land use and the ages of the traditional houses affected the intensity of the termite attacks. Several measures for avoiding and/or suppressing termite attacks on cultural heritage buildings are also proposed.

“…Food preference tests showed that N and P are phagostimulants in the termite diet [11,31]. Properties such as hardness (density) and secondary compound contents can also be determinants of the choice and consumption of food items [32,33,34,35].…”

Wood is the main dietary item for most termites; however, supplementation with certain nutrients may occur via the ingestion of other available food resources in the ecosystem. The objective of this study was to evaluate the consumption of lichens with different C, N, and P contents by Constrictotermes cyphergaster under laboratory conditions, and estimate the intake of this substrate by this species in a semi-arid area of Northeast Brazil. The foraging activities of fifteen field colonies were monitored over 15 days from 6:00 p.m. to 6:00 a.m., and the lichens that were consumed were identified. Blocks of lichen thallus (1.5 × 1.5 cm) of four lichen species were offered to the termites in the laboratory. The mean total consumption rate of lichen by C. cyphergaster was 0.032 mg lichen/g termite (fresh weight)/day. Dirinaria confluens was the lichen most consumed by termites (0.010 mg lichen/g of termite (fresh weight)/day), followed by Lecanora spp. and Haematomma persoonii at a mean consumption of 0.008 and 0.006 mg lichen/g termite (fresh weight)/day, respectively. Based on the size of the C. cyphergaster populations, the estimated lichen consumption rate was 105.12 g lichen/ha/year. Lichen consumption was significantly affected by the N content and the C:N and C:P ratios, with the N content being the factor that best explained the consumption by the termites. The results suggest that C. cyphergaster can use lichens as a supplemental source of nutrients, especially nutrients that are found in low concentrations in wood.
