“…Alternatively, preference for a humid area may indicate the use of humidity as a host habitat location cue for oothecal parasitoids to locate cockroach harborage sites. Due to high water loss rates (Appel et al, 1983), their synanthropic cockroach hosts (P. americana, Periplaneta fuliginosa (Serville), and Blatta orientalis (L.)) often distribute patchily in humid microhabitats around residential properties, such as tree holes, woodpiles, sewers, and crawlspaces (Fleet et al, 1978;Appel and Rust, 1985;Thoms and Robinson, 1987;Brenner, 1988;Tee et al, 2011a). The preference of E. appendigaster males for a humid area (76% RH) also supports the use of a humidity gradient as a host location cue for E. appendigaster females.…”

“…In this study, our results showed that reduced CP is critical for E. appendigaster and A. hagenowii to counteract the desiccation risk associated with small body sizes; the smaller the body size, the lower the CP values in these oothecal parasitoid wasps. This adaptive physiological trait resulted in lower water loss rates in these ootheca parasitoids (except A. hagenowii males) compared to their cockroach hosts of larger body sizes (P. americana, Periplaneta australasiae (F.) and B. orientalis: CP, 43.1-53.7; water loss rate, 1.82-2.44% h -1 ) (Appel et al, 1983).…”

“…Mass (water) loss in the first 2 h was used to calculate CP because maximal water loss occurred during this period as a result of the maximum water gradient between the insect and the desiccating chamber. The effect of reduced water loss rate at subsequent observation periods (due to changing body shape and hemolymph osmolarity and compartmentalization of water in the cuticle and body tissues) on interpretation of CP can be minimized (Appel et al, 1983;Mazer and Appel, 2001). We used Meeh's formula (Meeh, 1879), S = 12M 2/3 , to estimate body surface area of the parasitoid, where S = body surface area (cm 2 ) and M = initial mass (g) (Mazer and Appel, 2001).…”

“…(19.0 g cm Ϫ2 h Ϫ1 mmHg Ϫ1 ). The low CP explains the success of these cockroaches being ubiquitous widespread (Appel et al 1983). However, 79% TBW was lost in adult P. fuscipes 24 h after exposure to dry condition (Table 4; Fig.…”

Influence of Temperature on Survival and Water Relations ofPaederus fuscipes(Coleoptera: Staphylinidae)

The effects of four temperatures (15, 23.5, 28, and 35 degrees C) on the biological characteristics of the rove beetle Paederus fuscipes Curtis were studied, and its cuticular permeability also was measured. Specimens successfully developed to adulthood at each temperature tested, but development time of each preadult stage significantly decreased with increasing temperature. Both egg and L1 stages required at least 80 degree days above a threshold of approximately 10 degrees C to develop to the subsequent stage. The lengthy development time and high survival rate of preadults at 15 degrees C suggests that P. fuscipes can survive in a harsh environment during cold weather by hibernating, and this ability could allow preadults to succeed ecologically in temperate countries. However, adult longevity was short, and no fecundity was recorded at 15 degrees C. At 28 degrees C, P. fuscipes exhibited a high survival rate of adults, which had a longer life span and high fecundity; thus, the population had the highest intrinsic rate of increase (0.0788 +/- 0.0051 d(-1)) and the shortest mean generation time (48.57 +/- 1.43 d) at 28 degrees C. At this temperature, the population might reach a size that could facilitate invasion into residential areas. However, in the absence of a hygric environment, P. fuscipes was unable to survive despite favorable temperature. Unlike in adults and pupae, high cuticular permeability values were found in the larval stages. This indicates that larvae are highly susceptible to desiccation, and it explains why the distribution of P. fuscipes is restricted to moist habitats.

“…Experimental powder baits containing 0.25, 0.5, or 1.0% indoxacarb (DuPont), an experimental gel bait containing 0.25% indoxacarb, and commercial bait formulations containing 0.05% abamectin (Avert powder and gel baits) were supplied by Whitmire-MicroGen (St. Louis, MO). Water content and desiccation rate of the 0.05% abamectin and 0.25% indoxacarb powder and gel baits were determined because of the importance of water to cockroach biology (Appel et al 1983, Cochran 1983) and possible effects of bait dehydration on feeding and therefore bait toxicity (Appel 1992, Appel andBenson 1995). Bait (Ϸ0.5 g) was deposited on each of six preweighed aluminum pans and held at 25Ð28ЊC and 30 Ð 45% RH.…”

Experimental indoxacarb powder and gel baits were evaluated in the laboratory, and a gel bait was evaluated in subsequent field studies against the German cockroach, Blattella germanica (L.). In continuous exposure tests, LT50 values were 1.90 and 1.10 d for 0.25 and 1% indoxacarb powder baits, respectively. However, 0.25% indoxacarb gel bait had an LT50 value of 0.68 d, similar to a 0.05% abamectin gel bait formulated with the same bait base. There was no difference in toxicity between fresh and 7-d-old gel bait deposits. A pyrethroid-resistant strain of German cockroaches was significantly resistant to both abamectin and indoxacarb gel baits. Gel bait contained approximately 40% water, desiccated rapidly at 25-28 degrees C and 30-45% RH, but did not rehydrate when held at 56.7% RH for 3 d. Powder indoxacarb baits contained <1% water and did not desiccate or gain water. Indoxacarb gel bait (0.25%) was relatively nonrepellent (approximately 30%) and had positive maximum performance index values (approximately 100) in Ebeling choice box experiments. In field experiments in cockroach-infested kitchens, the 0.25% indoxacarb gel bait significantly reduced visual counts of German cockroaches approximately 74% at 3 d and >95% at 14 d. Indoxacarb baits are toxic, relatively nonrepellent, and can significantly reduce German cockroach populations.
