Concentrations of 22 elements in pinewood were compared with that in frass produced by insects representing the following taxa: Reticulitermes spp. (Rhinotermitidae), Zootermopsis nevadensis (Termopsidae), Incisitermes snyderi (Kalotermitidae), Hylotrupes spp. (Cerambycidae), Heterobostrychus spp. (Bostrichidae), Lyctus spp. (Bostrichidae), and representatives of the family Ptinidae (formerly Anobiidae). Twenty elements (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Si, Sr, and Zn) were measured using inductively coupled plasma‐optical emission spectroscopy (ICP‐OES), whereas carbon, hydrogen, and nitrogen percentages were measured using a CHN autoanalyzer. Chromium was the only element present at a statistically lower concentration in all frass types compared to pinewood. A comparison of pinewood to frass from those taxa that fed on pine revealed that Reticulitermes frass contained significantly higher levels of 15 elements, Zootermopsis 10, Ptinidae 5, Incisitermes 4, and Hylotrupes 1. Only Incisitermes frass showed a significantly higher percent carbon than pinewood and Reticulitermes, Zootermopsis, and Ptinidae showed significantly higher percent nitrogen. Examination of percent approximate digestibility (PAD) indicated that Reticulitermes frass had 14 elements that were ≥200% more concentrated than found in pinewood, whereas Zootermopsis had 6, Lyctus 5, ptinid 4, Hylotrupes and Heterobostrychus 3, and Incisitermes none. This survey of elements in frass indicates that saproxylic insects are, for the most part, not sequestrating but rather recycling (releasing) the store of micronutrients in wood biomass, with the greatest potential contribution to soil nutrient cycles attributable to subterranean termites.

“…Timber characteristics such as moisture, starch content and vessel size suitable for the insertion of the ovipositor of the lyctid beetles are the factors that determines the susceptibility of the timber to the pests (Peters et al 2002, Ito 1983). Kartika and Yoshimura (2013) confirmed the importance of starch and sugar to attract adult females of L. africanus to lay their eggs on starchy sites. In general, it is difficult to detect the initial stages of infestation of this beetle and is unnoticed until attack is much advanced.…”

The management of Lyctus africanus, one of the major dry wood pests in the tropical region is difficult due to its secluded habits and long lifecycle and therefore, its control measures are limited to the usage of insecticides. The insecticides particularly the metal salts are effective, but in some cases their leaching leads to concerns about environmental pollution. Nanometal particles are found to be more effective than metal salts. Presently available metal nanoparticles are synthesized using physical or chemical methods and their production results in toxic by-products and are costly. The current investigation deals with synthesis and use of metal nanoparticle for wood protection in an environmentally friendly and cost-effective way. The plant extracts that are reported to have wood preservative properties were used for the synthesis of metal nanoparticles. Copper oxide and zinc oxide nanoparticles were synthesized using leaf extracts of Lantana camara. The efficacy of the synthesized Lantana camara leaf extract and copper oxide or zinc oxide nanoparticle formulation as a wood protectant was tested against Lyctus africanus according to standard BIS. The formulation of copper oxide nanoparticle and Lantana camara leaf extract effectively protected the treated rubberwood blocks from Lyctus africanus attack, when compared to zinc oxide nanoparticle Lantana camara leaf extract formulation and can be developed into a stable, ecofriendly wood preservative.

“…Collecting such eggs unharmed from bamboo pieces would be very difficult, and an alternative method was needed. Kartika and Yoshimura [9] and Baba and Ainara [10] reported techniques utilizing nutrientcontaining filter paper to collect eggs of the powderpost beetle species Lyctus africanus and L. brunneus, respectively, and we adapted these techniques for D. minutus. Sheets of filter paper cut into 26 9 65 or 26 9 20 mm rectangles were soaked in an aqueous suspension containing 10% corn starch and 10% granulated sugar, and then dried at 60°C for 1 h. Five-layered laminates of treated filter paper were formed by folding sheets of 26 9 65 mm four times or stacking five sheets of 26 9 20 mm.…”

Nondestructive evaluation of egg-to-adult development and feeding behavior of the bamboo powderpost beetle Dinoderus minutus using X-ray computed tomography

The life history and feeding biology of the bamboo powderpost beetle Dinoderus minutus remain poorly understood because the beetles' oviposition, development, and feeding take place inside bamboo culms. In this study, X-ray computed tomography (CT) was employed to nondestructively quantify the progression of larval body size and tunnel size from the first instar to pupation. Eggs of D. minutus laid between laminates of nutrient-containing filter paper were easily collected. The newly hatched larvae were inoculated singly into pieces of internodes of madake (Phyllostachys bambusoides). The pieces were scanned using a microfocus X-ray CT system every 3-5 days to visualize the beetles' bodies and tunnels with resolutions of 18-60 lm/voxel. CT scans were continued after adult eclosion to analyze pre-mating adult feeding. The collected eggs were 0.84 ± 0.06 mm (mean ± SD) in length and the egg duration lasted 5.0 ± 0.8 days. Based on CT images, the larvae grew to 3.53 ± 0.23 mm in body length and turned into pupae of 3.42 ± 0.09 mm. The larvae bored tunnels with a length of 80.2 ± 4.8 mm and a volume of 68.0 ± 7.0 mm 3 over the larval period of 61 ± 11 days. Newly emerged adults remained in the bamboo pieces to feed before making exit holes in 8 ± 1 days after adult eclosion. During this period, they bored tunnels at rates of 2.64 ± 0.58 mm/day in length and 4.87 ± 1.10 mm 3 /day in volume.
