“…Synergistic (greater than additive) gene interactions have been noted previously in pesticide-resistant strains of insects (Arnold and Whitten, 1976;Raymond et al, 1989;Shono et al, 2002). However, examples of field-collected strains containing synergistically interacting genes are very rare.…”

Phosphine, a widely used fumigant for the protection of stored grain from insect pests, kills organisms indirectly by inducing oxidative stress. High levels of heritable resistance to phosphine in the insect pest of stored grain, Rhyzopertha dominica have been detected in Asia, Australia and South America. In order to understand the evolution of phosphine resistance and to isolate the responsible genes, we have undertaken genetic linkage analysis of fully sensitive (QRD14), moderately resistant (QRD369) and highly resistant (QRD569) strains of R. dominica collected in Australia. We previously determined that two loci, rph1 and rph2, confer high-level resistance on strain QRD569, which was collected in 1997. We have now confirmed that rph1 is responsible for the moderate resistance of strain QRD369, which was collected in 1990, and is shared with a highly resistant strain from the same geographical region, QRD569. In contrast, rph2 by itself confers only very weak resistance, either as a heterozygote or as a homozygote and was not discovered in the field until weak resistance (probably due to rph1) had become ubiquitous. Thus, high-level resistance against phosphine has evolved via stepwise acquisition of resistance alleles, first at rph1 and thereafter at rph2. The semi-dominance of rph2 together with the synergistic interaction between rph1 and rph2 would have led to rapid selection for homozygosity. A lack of visible fitness cost associated with alleles at either locus suggests that the resistance phenotype will persist in the field.

“…cyclodiene resistance in most insects via Rdl) or polygenic (e.g. pyrethroid resistance in house flies (Keiding, 1999;Shono et al, 2002) or organophosphate resistance in Culex mosquitoes ). With continued selection, new resistance alleles can arise and replace existing alleles (Chevillon et al, 1999;Lenormand et al, 1999;Raymond and Pasteur, 1996;Rivet et al, 1993).…”

“…Two major resistance mechanisms have evolved in response to pyrethroid use: mutations in the voltage-sensitive sodium channel (kdr, super-kdr, and kdrhis) and P450 monooxygenase-mediated detoxification. The Vssc1 kdr allele (L1014F) has been found globally, while the super-kdr allele (M918T+L1014F) has been found in Europe and Asia (Huang et al, 2004;Shono et al, 2002;Williamson et al, 1993), but not in the USA (Liu and Yue, 2001;Scott and Georghiou, 1986;Shono et al, 2002). The M918T mutation is not found in the absence of the L1014F mutation (Soderlund and Knipple, 2003) and it appears that the super-kdr allele evolved from the kdr allele (Rinkevich, 2005).…”

“…There is evolutionary plasticity in the evolution of resistance via monooxygenase-mediated detoxification (Festucci-Buselli et al, 2005;Scott and Kasai, 2004), with different P450 genes responsible for resistance in different populations. For example CYP6D1v1 confers pyrethroid resistance in house flies in the eastern USA, but not in Japan (Shono et al, 2002).…”

SUMMARY Because the eyes of insects cannot be moved independently of the head,information about head posture is essential for stabilizing the visual world or providing information about the direction of gaze. We examined the external anatomy and physiological capabilities of a head posture proprioceptor, the prosternal organ (PO), located at the base of the neck in the black soldier fly, Hermetia illucens (L.) (Family: Stratiomyidae). The PO is sexually isomorphic and is composed of two fused plates of about 130 mechanosensory hairs set in asymmetrical sockets whose orientation varies across the organ. A multi-joint mechanical coupling between the head, neck membrane, and contact sclerites deflects the hairs more or less to increase or decrease their level of excitation. The PO sensory afferents project to the central nervous system (CNS) via a pair of bilateral prosternal nerves (PN) to the fused thoracic ganglia. Simultaneous recording of spiking activity in the PN and videotaping of wind-induced and voluntary head movements around all three axes of head rotation reveal that a few PN afferents are active at rest, but activity increases tonically in response to head deflections. Activity is significantly modulated by change in head angles around the pitch (±40°), yaw (±30°) and roll (more than±90°) axes, although the dynamic range of spiking activity differs for each axis of rotation. Prosternal nerve afferents are bilaterally excited(inhibited) by pitch down (up); excited (inhibited) by head yaw toward the ipsilateral (contralateral) side; excited by roll down toward the ipsilateral side, but little inhibited by roll toward the opposite side. Although bilateral comparison of activity in PN afferents reliably encodes head posture around a given rotational axis, from the point of view of the CNS, the problem of encoding head posture is ill-posed with three axes of rotation and only two streams of afferent information. Furthermore, when the head is rotated around more than one axis simultaneously, mechanical interactions in the neck modify the responses to postural changes around the three rotational axes, which adds further ambiguity to reliable encoding of head posture. The properties of the PO in this relatively basal fly species are compared to those of higher flies and possible mechanisms of disambiguation are discussed.
