Abstract:
The proportion of possums with cyanide-shyness was assessed in four populations and ranged from 12 to 54%. These results supported anecdotal evidence of cyanide-shyness and showed that the problem could be significant in some populations. Non-toxic baiting with rhodamine dye as a marker indicated that more than 90% of possums were willing to accept the bait material, and pen trials showed that possums were able to eat the bait material but reject the cyanide paste placed in the bait. Shyness was therefore not a result of bait aversion but of direct rejection of the toxin. Attempts to induce shyness in possums by feeding them sublethal doses of cyanide, and the history of cyanide use in the trial areas, support the theory that at least in some areas cyanide-shyness is not a result of previous exposure (learned aversion) but of primary aversion. Current research to produce cyanide formulations with low emission rates of hydrogen cyanide aims to make the toxin effective even in areas where cyanide-shyness has developed.

Abstract:
Shyness to sodium monofluoroacetate (1080) in cereal bait can persist in sub-lethally poisoned possum (Trichosurus vulpecula) populations for at least 2 years. We investigated the use of non-toxic cereal ‘prefeed’ and ‘postfeed’ as ways of inhibiting and overcoming such shyness. The postfeed result was also compared with changing to a non-cereal, gel-based 1080 bait. Prefeeding had a significant effect on the number of possums that became ‘bait shy’ following an approximate LD20 1080 dose, with 97% of non-prefed possums developing an aversion to 1080 cereal bait compared with only 22% of prefed possums. In contrast, postfeeding with cereal was relatively ineffective in reducing the number of 1080 bait-shy possums, with mortality of these possums being 30% compared with 0% of non-postfed possums. In contrast, the gel 1080 bait killed 64% of 1080 cereal bait-shy possums. These results suggest that 1080 bait shyness can be markedly reduced by prefeeding non-toxic bait to possums prior to each control operation. However, this may not be the most cost-effective control option, given the observed efficacy of follow-up baiting with 1080 gel.

Abstract:
Development of aversions, or learned ‘bait-shyness’, in frequently poisoned possum (Trichosurus vulpecula) populations is becoming increasingly detrimental to the efficacy of pest-control operations in New Zealand. This experiment aimed to identify the effects of prefeeding, a common management procedure, on the subsequent development of aversions in possums. Wild possums (n = 96) were captured and acclimatised, then allocated to one of three treatments groups that for seven days received either (i) no prefeed, (ii) plain RS5 cereal baits, or (iii) green-dyed and cinnamon-lured RS5 cereal baits. The possums were then offered a standard green-dyed and cinnamon-lured RS5 bait that contained a sublethal dose (0.4 mg kg-1) of the toxin sodium monofluoroacetate (1080). The possums were tested for development of an aversion towards a toxic RS5 1080 bait, a prefeed bait, and a prefeed bait containing an alternative toxin, brodifacoum. Most (96%) of the non-prefed possums became averse to the 1080 bait after two exposures, compared with only 55% and 9% of the two prefed groups. Similarly, 90% and 92% of the non-prefed possums were averse to prefeed and brodifacoum baits, respectively, compared with 8% and 14% of the prefed possums. This suggests that pest managers can reduce the risk of ‘bait shyness’ by prefeeding. A further advantage of prefeeding is that if poison shyness develops, use of an alternative toxin such as brodifacoum in the original bait base may still be successful.

Abstract:
The probable cause of possums (Trichosurus vulpecula) becoming 'shy' towards 1080 [sodium fluoroacetate] bait, a growing problem in the control of this pest, was determined. Possums captured from North Canterbury, New Zealand, (n = 131) were offered sublethal baits (1 or 2.5 g) followed by lethal (6 g) baits 2 days later. Most possums became bait shy and the proportion becoming shy appeared to be related to the size of the initial sublethal dose. Most of a group of survivors retested after 3 months with toxic pellets were still shy. Shyness was not overcome by changing to a different mask (orange flavour, as opposed to cinnamon flavour) or toxin (brodifacoum), but changing to both a different bait base (carrot) and mask (orange) resulted in most shy possums eating a lethal quantity of bait. Possums therefore appeared to learn to recognise the bait base as the cue for avoiding poisoning. More shy possums than naive possums rejected non-dyed, non-masked, non-toxic pellets, confirming that shy possums recognised the bait base. Green dye appears to act as a secondary cue for avoiding pellets as a higher percentage of 'shy' possums than naive possums rejected dyed baits.

Abstract:
Management of rodent with rodenticide and trapping is frequently ineffective due to bait or trap shyness and neophobia. A study was conducted in the laboratory of Vertebrate Pest Division, BARI, Gazipur and field to increase the attractiveness of bait or trap to B. bengalensis and enhance the consumption of novel food by using different concentration of carbon disulfide (CS2). Study revealed that addition of CS2 improved bait acceptance of food. Five ppm concentration of CS2, rat consumed significantly greater amount of cereal bait than untreated plain wheat bait. In semi-natural field test, significantly greater number (59%) of rat was trapped in CS2 scented bait than without scented bait (41%). In the field study higher population reduction (85-91%) was achieved with CS2 scented zinc phosphide bait than without scented zinc phosphide bait (50%). That is 80% higher reduction of rodent population was achieved with CS2 treated zinc phosphide bait. From this study we conclude that CS2 can improve the efficiency and consumption of poison bait and can increase trap success.SAARC J. Agri., 14(1): 93-101 (2016)

Abstract:
A method is presented for quantitatively assessing the likely effectiveness of specific bait size and 1080 concentration for controlling brushtail possums with a known weight distribution. Data from aerial 1080 operations for the control of brushtail possums in New Zealand show that estimates of the bait size and toxic concentration required derived from the mean parameters [pest weight, bait size, and lethal dose (LD 95)] will not be accurate. This inaccuracy is most likely to lead to an underestimate of the amount of toxin presented to each animal, so that many operations currently run the risk of sub-lethally dosing possums and thereby possibly inducing some degree of poison shyness. On the basis of more accurate quantitative assessments of bait effectiveness we recommend that the 1080 concentration be increased to 0.15% and that baits less than 5 g be excluded to ensure that when mean possum weights are less than 3 kg more than 95% of possums are lethally dosed by a single bait.

Abstract:
Abstract Two new anticoagulants (bromadiolone—90% control) and (difethialone—87% control) gave excellent control of voles in field and laboratory tests. The older anticoagulants, chlorophacinone—84% control and diphacinone—75% control, and two zinc phosphide formulations (Bell Labs—84% control and Hopkins—79% control) also gave excellent field control of voles. The Ridall zinc phosphide formulation—61% control, and cholecalciferol (vitamin D3)—59% control did not perform as well as the other rodenticides previously mentioned. The antibiotic, oxytetracycline, killed from 40% to 80% of pine and meadow voles in laboratory trials when applied to cut apples, but only 10 to 30% when pelletized baits were presented. In a mixed pine and meadow vole orchard population, zinc phosphide raised the ratio of surviving pine to meadow voles while anticoagulants lowered the ratio. Thus, the rotation of rodenticides is thought to be desirable to prevent the shift of one species to the other in mixed populations and to prevent bait shyness from developing to zinc phosphide.

Abstract:
An individual will perform self-impression to be accepted by society and can establish a social relationship. Someone do the self presentation so they can be accepted by the environment. However, there are some people which have obstacle to do their self presentation to make a social relationship. We can called that condition with shyness. Social media can be well accepted a mediator for shy person to presented their self. The purpose of this research is to find out the correlation between shynees with self presentation on adolosence in social media. This research has done to 96 sample of 13 – 16 years old active user of social media like Facebook, Twitter, Path, Instagram, Blog, and Youtube. The result with Pearson Product Moment test says the coeficient correlation (r) between two variables is 0,281. That is shows that between the two variables have a positive correlation with the signification level is 0,006 (p < 0,05) which says that the two variables have a significant correlation.Abstrak: Individu akan melakukan pengelolaan kesan agar dapat diterima oleh masyarakat dan dapat menjalin sebuah hubungan sosial.
