“…Manuscript to be reviewed Discussion Currently, chemical poisoning using agents such as anticoagulant rodenticides and zinc phosphide remains one of the most important methods for rodent pest control (Haim et al 2007;Labuschagne et al 2016;Liu 2019). EBRM has recently been implemented in several countries, such as Vietnam and Indonesia as well as in the African continent, and mainly involves the use of trap-barrier systems, community rat hunting campaigns, and habitat management (Brown et al 2005;Brown & Khamphoukeo 2007;Jacob et al 2008;Massawe et al 2011;Singleton et al 2005;Wang et al 2017). The addition of fertility control as an ecologically friendly method has not yet been widely possible.…”

Background. Rodent pests can inflict devastating impacts on agriculture and the environment, leading to significant economic damage associated with their high species diversity, reproductive rates, and adaptability. Fertility control methods can indirectly control rodent pest populations as well as limit ecological consequences and environmental concerns caused by lethal chemical poisons. Brandt's voles, which are common rodent pests that are found in the grasslands of middle-eastern Inner Mongolia, eastern regions of Mongolia, and some regions of southern Russia, were assessed in the present study. Methods. We evaluated the effects of levonorgestrel, quinestrol, and a 1:1 mixture of the two (EP-1) on reproductive behavior as well as changes in the reproductive system, reproductive hormone levels, and toxicity in Brandt's voles. Results. Our results revealed that all three fertility control agents can cause sterility at a dosage of 2 mg/kg. However, quinestrol caused a greater degree of toxicity, as determined by visible liver damage and reduced expression of the detoxifying molecule CYP1A2. Of the remaining two fertility control agents, EP-1 was superior to levonorgestrel in inhibiting the secretion of follicle-stimulating hormone and causing sterility. We believe that these findings will help promote the use of these fertility control agents and, in turn, reduce the use of chemical poisons and limit their detrimental ecological and environmental impacts.

“…Though traditional physical tools like snap traps and cages are broadly used in rodent control in China, these tools are rarely used in large-scale rodent management because of high cost and high labor and time requirements. The trap barrier system (TBS) is a physical method originating from Malaysia (Lam 1983) that has been broadly applied in rodent management in Asia and Africa (Singleton et al 2005;Brown et al 2006;Belmain 2010;John 2014;Wang et al 2017). Originally, TBS was designed for rodent control in rice fields, which consist of an area of field with rice planted earlier as bait and surrounding plastic fence with traps (Lam 1983;Singleton et al 1998).…”

After TBS was introduced into China, it was adapted and broadly applied to rodent control in dry farmlands such as those used to grow maize (Wang et al 2017). Recent studies showed that the lure crop in TBS was unnecessary, and linear TBS with the same fence and traps as that of standard rectangle TBS set along farmland ridges could reach similar or even higher trap efficiency (Wang et al 2017).…”

China experiences serious agricultural damages from rodents, and, correspondingly, researchers in China are actively studying rodent biology and management. Following the popularization of ecologically-based rodent pest management and extension of the basic state policy of Ecological Civilization Construction in China, recent efforts in rodent control technologies are mainly focused on eliminating side effects of rodenticides and developing environmentally friendly techniques. Considering ecological functions of rodents to test their interaction with the environment is a promising design for understanding rodent populations in local ecosystems and for developing ecologically-based rodent management. Using ecological phenotypes and applying advanced techniques of molecular biology, genetics, and epigenetics might be useful for illustrating the deep regulatory mechanisms of fluctuations in rodent populations. However, facing the dual characteristics of rodents as pests and their roles as keystone species in many ecosystems, it is still a challenge to establish reasonable local thresholds to balance rodent management with the negative effects of rodent control on the environment in the future.

“…Although non-chemical methods of rodent control exist (Singleton et al, 2005b), these ecologically-based rodent management practices have largely been developed to deal with chronic rodent pest problems in agriculture as opposed to rodent outbreaks (Singleton et al, 2007). One successful non-chemical method of rodent control is the use of community-based trap barrier systems (TBS) to prevent rodent damage in lowland irrigated rice production systems (Jacob et al, 2010) and other cropping systems (Wang et al, 2017). A TBS consists of multiple-capture cage traps embedded within a plastic fence surrounding a rice crop that has been planted approximately two weeks earlier than the rest of the rice field, thus drawing rodents to the trap crop within the fenced area.…”

Impact of trap barrier systems on rodent damage to upland rice cropping systems during bamboo masting events

Synchronous bamboo masting events are well-known to cause rodent population outbreaks. In South Asia, Melocanna baccifera undergoes semelparous masting every 58 years leading to large rodent outbreaks and nearly 100% crop losses. Current crop protection methods used to control rodent outbreaks are largely based on large-scale use of chronic and acute poisons. Non-chemical control methods, such as the use of trap barrier systems (TBS), could be effective in such outbreak situations. However, TBS is currently used in lowland irrigated rice cropping systems, and thus would need to be evaluated and adapted to the upland rice production systems commonly found in the areas affected by bamboo masting induced rodent outbreaks. In this study we carried out field trials over two cropping seasons (2009 and 2010) in the Ruma area of the Chittagong Hill Tracts, Bangladesh during an on going bamboo masting event. Rodent activity was measured through active burrow counting in TBS fenced and unfenced rice crop fields. No rodent activity was found in TBS fenced fields in 2009, with some limited activity in TBS fenced fields in 2010. In 2010, the mean number of active burrows in unfenced fields was 8.66/ha, compared to 1.8/ha in the TBS sites. Rodent damage was measured by counting rice tillers cut by rodents, with no damage observed in TBS fenced fields in 2009, with some limited damage in TBS fenced fields in 2010 (0.26% damage), whilst unfenced field tiller damage was 3.2% during 2009 and 1.77% during 2010. The main rodent species captured by multi-capture traps in the TBS fences were Rattus rattus (70%), Mus musculus (19%), Rattus nitidus (5%) and Cannomys badius (5%). Rodent capture rates and crop damage were much lower than expected, which is arguably explained by an absence of rodent outbreaks in the selected communities, despite bamboo masting occurring in the surrounding forests around the rice fields. The using of TBS during the rodent outbreaks followed by Melocanna bamboo flowering is discussed in terms of the cost-benefits to prevent rodent damage in upland rice cropping systems.
