The present paper reports on two lamellicorn beetles: Adoretus tennuimacu-latus Waterh. and Liocola brevitarsis Lew. The former belongs to the subfamilyRutelinae and the later Cetoniinae. Adoretus tennuimaculatus has two generations per year at Lientang. Thefirst active period of adults mostly occured in June and the second period inAugust. After 7: 30 at night, the adults went out and stayed on various hostplant leaves feeding or copulating and then back into earth at dawn. Larvaewere not strict in selecting the soil but most of them lived in the garden soil,mound soil and. clay landside. Liocola brevitarsis has only one generation per year at Lientang. The adultperiod was from June to September and some of them lengthened out mid-Octo-ber. Adults flied out at day time and sucked the different part of hosts: as theflesh of fruit, the juice of tree and the corn ear, once in a few days. Larvaeselected the soils more strictly. They concentrated in compost and rich humussoil. Controlling methods: (1) To spray 0.5%γ666 or 25% DDT emulsion (250water:1 emulsion) once to the host leaves was effective in protecting against theadults of Adoretus till its last period of activity. (2) To shake the tree to makethe adults of Adoretus fall down and then unroll a piece of white cloth underthe tree to gather the adults. (3) To make a bamboo cylinder, 12-16 in. long,which was filled with rotten fruits and nectar, and trap all the adults of Liocolain this cylinder. (4) To clean out the compost before June in order to kill mostof the larvae and pupae of Liocola.

High percentage of chlamydospore germination of Neovossia horrida (Tak.)P.& K.with abundant basidiospore production was obtained by placing moistenedspores in a Petri dish with limited supply of water,the dish-cover being inkedblue to insure a favordable light condition.Moistened spores applied on the sur-face of kernels of a growing rice head enclosed in a paraffin paper bag was alsofound to germinate by producing a very short basidium and a large number ofbasidiospores.It is,therefore,concluded that not only light but also oxygen isrequired for normal germination of the spores of the rice kernel smut. Results of a series of inoculation experiments conclusively show that thefungus infects rice kernels during the milky dough stage.Basidiospore inoculationgives higher percentage of infection than chlamydospore inoculation. Field observation indicates that the incidence of high percentage of infectionis coincident with the excessive application of nitrogenous fertilizer.Fluctuationof the amount of infection from year to year is probably determined chiefly by theduration of high moisture period from heading to dough stage.There are someevidences of varietal difference in the susceptibility of rice to the kernel smut.

Sweet-potato wilt,a dangerous disease of sweet potatoes,has made itsappearance for more than 10 years in several districts of the south-easternKwangsi and south-western Kwangtung.During recent years it has been found tocause a heavy loss of sweet potato crop in these two provinces. Sweet-potato wilt is a kind of wilt disease which infects the fibrovascular ??bundles of the plant.It begins to infect the vine cuttings and those parts thatare in close contact with the sick-soil.The infected parts first show the water-soaked appearance and then extend upwardly,and eventually become blackenedand rotted.As a rule,ths leaves of the infected plants show an abnormal coloror pale yellow,and drooping appearance.In the meantime,the root tips of theadventitious roots of the vines lose their cortex and begin to lot.Wilting followsquite rapidly and finally the entire plant dies.If the disease infects the plantafter the potatoes beginning to form,it may extend throughout the vine and in-to the roots,causing the enlarged roots to show brown streaks and finally blackenedand rotted with pungent odor. The cause of the disease may appropriately be considered as due to bacteriaand Fusarium spp.Four types of bacteria,i.e.white smooth type,yellow smoothtype,white rough type and yellow rough type,are able to cause the disease.Atleast four kinds of Fusarium,i.e.white aerial mycelium type,white mycelium withred of a purple tint substratum type,pink mycelium with red of a purple tint sub-stratum type and without aerial mycelium type are responsible for the disease.Which is the main cause of the disease? Either bacteria or Fusarium alone or theboth in combination is able to cause the disease,further tests should be madebefore a definite conclusion may be drawn. The dissemination of the wilt organisms may appropriately be considered inthree ways,namely,(1) by infested roots and vines,(2) by sick-soil,and (3) byinsects,as the sweet-potato weevil (Gycas formicarius Fabr.).The former twoways of dissemination are more definite than the latter,however,further testsand observations should be made. According to the results of 2-years field experiments in Tsen-shi and Peh-liustations,it shows that different varieties of sweet-potato possess different resis-tance to the disease.Among several varieties tested,it is found that Tai-nung No.3being a promising one,because it yields very high and is highly resistant to thedisease and to the drought.Although it is occasionally found to be susceptibleto the disease in the experiment field of Tsen-shi and is more commonly foundin the experiment field of Lin-kwei.The second variety is Tai-nung No.46 dueto its high degree of disease resistance. The results of preliminary tests indicate that the method of reproduction byold vines would decrease both in disease resistance and in yield within the samevariety. From tests conducted in two different fields,i.e.one at dry land and the ??other in the rice field,it shows that the discrepancies were found in the occur-rence of the disease and also in the relation of the method of manuring to thepercent of infection. Dipping cuttings in different disinfectants did not show any significant results.There are discrepancies in both plowed and sunned field test and two methodsof setting the vines test.These may be due to methods of treatment,landand varieties used for experiment being different. According to the results of date of planting tests in Peh-liu,it indicates thatthe occurrence and the development of the disease are closely related to the highhumidity and the high temperature.These climatic factors affect the health ofthe early growth of the plant which in turn would increase the disease resistance.It is suggested that the most suitable date for planting sweet-potato in Peh-liu isin the first decade of August. In comparing the weather records of the three districts—Lin-kwei,Peh-liu andTsen-shi—in relation to the date of early and last occurrences of the disease,itshows that an average air temperature of 23.4-28.4℃ is most suitable for the oc-currence of the disease,and an average relative humidity of 80 per cent is alsoneeded for the infection of the disease.Based on these facts,we may say thatsweet-potatoes in Lin-kwei are capable to be easily infected by the wilt organisms.except the last date of the infection would be preceded 10-20 clays.Any otherregions with similar climatic factors,it is also very possible to be infected. According to the results of 2-years experiments and facts from surveys,sug-gestive control measures are proposed: (1) excluding the disease by regulationthrough the use of quarantines enforced by an inspection station empowered torestrict or eradicate diseased roots and vines to prevent them from becomingsources of infection in disease-free districts; (2) selection of disease resistant varie-ties in combination with cultural practices such as the use of more ash,suitableamount of lime and manure,and suitable date of planting to enable plants toescape or resist the disease.For the present time,we suggest that the use of Tai-nung No.3 in Tsen-shi and Peh-liu may meet the requirement,and promotingthe method of root reproduction in place of an old method of reproduction byrepeating vine cuttings from old vines can prevent the degeneration of the plantand decrease the infection of the disease.

甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之...

甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之一),临桂試驗田也会發生过多次。老藤繁殖会降低同一品种的抗病性和产量,值得我們注意。在旱地和水田不同試驗地上所得結果,可初步说明發病情况很不一致,追肥与不追肥处理的發病率也不一致。藥剂处理种苗效应不显著,翻晒土壤及二种种植法試驗结果不一致,想与試驗方法、試驗地不同和供試品种不同有密切关系。薯瘟的發生与發展和高温潮湿有密切关系,而这些气候因素对于植株的早期生??長壮健及增强抗病性也有关系。初步建議,在北流地区以立秋(8月上旬)种植較为适当。从临桂雁山、北流和岑溪三处的气候記录,和薯瘟开始發生与最后發生日期的記录看来,可以初步說平均气温23.4—28.4℃最适于薯瘟的發生。相对湿度平均在80%以上亦适于本病的發生。由此可見,在临桂雁山地区,薯瘟可能是容易發生的,不过停止發病日期会提早10—20天。其他地区如有相似气温与湿度情况,那也是会發生薯瘟的。根据二年試驗結果和調查所得情况,初步提出防治薯瘟的办法如次:(1)应采取种薯和种苗的檢疫措施,禁止病区的种薯运往無病地区,以防蔓延;(2)选育抗病品种为主,結合先进的栽培管理法;多施草木灰,适当施用石灰,根外追肥,适期种植等,以增强植株的抗病性,避免病害的侵染,保証丰产。目前在岑溪及北流地区,可先推广种植“台农三号”品种,并提倡以薯塊育苗,切勿采用老藤繁殖,以避免植株的衰退,减少薯瘟的發生。
