    ABSTRACT: Sorghum is the fifth most important cereal and suffers heavy damage from rice weevil Sitophilus oryzae, reducing their quality and quantity. Studies were conducted to identify the association of grain characteristics and their relationship with resistance to the rice weevil. The paper discusses the associations between sorghum seed parameters, insect oviposition, development data and grain weight loss. The important grain characteristics, viz., 100 seed weight was significantly positively correlated with grain hardness (0.55**) and median development period (0.47**) and significantly negatively correlated with grain weight loss (- 0.43*). However, the grain hardness was significantly negatively correlated with oviposition (- 0.49**), adult emergence (- 0.75**) and grain weight loss (- 0.82**) and was significantly positively correlated with median development period (0.85**). The pest parameter, viz., oviposition was significantly positively correlated with adult emergence (0.43*) and grain weight loss (0.55**). Two principal components (PCs) were extracted explaining cumulative variation of 76.2 %. Seed weight, grain hardness, oviposition, adult emergence, median development period and grain weight loss were the reliable variables for characterization of resistance to S. oryzae. The sorghum lines EC 24, EC 22, PEC 8, PEC 7, EP 78, EP 57, AKR 354 were classified as resistant to S. oryzae and these could be used in future breeding program as resistant sources.

    ABSTRACT: Mycosphaerella musicola produces various toxins known to play a key role in pathogenicity and disease development. In our study secondary metabolites produced by M .musicola was extracted and investigated using different parameters. The investigation was aimed to understand the phytotoxic resistance of locally growing different Musa genotypes (AB-Elakki (ELA), AAA-G9 (G9) and AAB-Nanjangud Rasa Baley (NRB)) against the crude extract and partially purified lipophilic TLC fractions extracted from the culture filtrates of M. musicola. Susceptible and resistant banana genotypes against the crude extract and partially purified fractions were analyzed by electrolyte leakage assay and leaf puncher assay. The results revealed that the crude extract and TLC fractions showed varied phytotoxicity among the banana leaves belonging to different age groups and different genotypes. Phytotoxicity studies allowed us to observe that ELA and G9 exhibited resistance to crude extract and TLC fractions, indicating that these genotypes are resistant to initial M. musicola infection.

    ABSTRACT: Pratylenchus brachyurus stands out among the major importance nematodes for the national agriculture, due your difficulty of control. Thus, the study aimed to evaluate the efficiency of resistance inductors in the nematode management in resistant and susceptible maize. It was studied the inductors acibenzolar-S-metil, Ecolife™ and manganese phosphite. The experiment was conducted in a factorial arrangement (2 × 4) composed for two maize genotypes (resistant and susceptible to nematode). Each inductor was applied, singly, seven days and one day before inoculation and seven days after inoculation to nematode. Untreated plants were used as control. The inductor Acibenzolar-S-metil was efficient to reduce the nematode population in both genotypes. Ecolife™ promoted the nematode reduction in susceptible genotype while the results were variable for manganese phosphite. In general, the inductors showed no significant effect on plant development and the same factor mainly affected by genotype.

    ABSTRACT: Transgenic Bt cotton BG II (cry1Ac +cry2Ab genes) in comparison with non-Bt cotton were evaluated for their effect on the development of Spodoptera litura in the IPM Laboratory of Department of Entomology, Punjab Agricultural University Ludhiana. The leaf and square of various Bt cotton cultivars viz. MRC 7017, BCHH 6488, BCHH 6588, Ankur 3028, NCS 855 and non-Bt cotton LH 2076 were fed to the neonates, first and second instars larvae of cotton leaf worm, S. litura. The neonates, 1st and 2nd instar larvae when fed on leaves of transgenic Bt cotton resulted in 100 per cent mortality as compared to non-Bt cotton (0.00). However, 2nd instar larvae fed on squares of Bt cotton resulted in 100 per cent mortality in most of the Bt cotton cultivars, MRC 7017, BCHH 6488, BCHH 6588 and Ankur 3028 except NCS 855 (82.16) and non-Bt (6.63). The developmental times of 2nd instar larvae of S. litura were different among Bt cotton cultivars and non-Bt cotton. The survived 3rd instar larvae fed on leaves in Ankur 3028 (11.11) followed by BCHH 6588 (7.14) and BCHH 6488 (7.4) continued to be 3rd instar even after 17 days, while those on non Bt cotton moulted to pupal stage (7.14). However, when larvae fed on squares of Bt cotton and non-Bt cotton, maximum pupation takes place in non Bt cotton cultivar, LH 2076 (93.33) followed by Bt cotton cultivar NCS 855 (17.85) after 24 days. The total developmental time of larvae in the Bt cotton was significantly longer than that of larvae on non-Bt squares. The higher weight of larvae fed on leaves was recorded in LH 2076 (19.72 mg). Similarly, after 10 days of release of S. litura on squares of different cotton cultivars higher weight of larvae was recorded in LH 2076 (25.671 mg) and lower in MRC 7017 (2.919 mg). The pupae that developed from the larvae that fed on non-Bt were heavier than those that developed from the larvae that fed on non-Bt cotton squares. After 27 days, 100 per cent adult emergence was recorded in non-Bt cotton cultivar, LH 2076 followed by single emergence in BG II cotton cultivar NCS 855. However, after 31 days, four adults were formed in case of NCS 855 but they were not able to survive for more than 2 days and all of them were males. It can be inferred that all BGII cotton cultivars were toxic to neonates, first and second instar larvae of S. litura under laboratory conditions.

    ABSTRACT: A leaf blight on oil palm, caused by Alternaria longipes, was found in an Elaeis guineensis plantation for the first time in Chiang Mai Province, Thailand. The fungus was isolated from the lesions and its pathogenicity was confirmed. The fungus was identified based on morphological characteristics and confirmed using comparisons of DNA sequences of internal transcribed spacer (ITS) regions 1 and 2 plus 5.8S rDNA. This report is the first on oil palm leaf blight disease caused by A. longipes.

    ABSTRACT: An age-stage two-sex life table was constructed in order to investigate the differences in population characteristics between Bradysia odoriphaga Yang and Zhang individuals reared on artificial diet, Chinese chive [Allium tuberosum], Welsh onion [Allium cepa], cucumber [Cucumis sativus], lettuce [Lactuca sativa], and Chinese cabbage [Brassica rapa pekinensis]. A population projection was also used to determine the potential trend of populations. The intrinsic rates of increase (r) of B. odoriphaga reared on artificial diet, Chinese chive, Welsh onion, cucumber, lettuce, and Chinese cabbage were 0.1477, 0.1545, 0.1295, 0.1405, 0.1294, and 0.0732 d-1, respectively. The highest net reproductive rate was 61.26 offspring per individual reared on Chinese chive, followed by 53.19, 49.90, 38.15, 30.54, and 16.20 offspring per individual for populations reared on artificial diet, Welsh onion, cucumber, lettuce, and Chinese cabbage, respectively. The mean generation times of B. odoriphaga ranged from 25.88 days when reared on cucumber to 37.86 days when reared on Chinese cabbage. B. odoriphaga feeding on Chinese cabbage had the longest total preoviposition period of female insects from birth (TPOP), larval and pupal period, and the lowest fecundity, and this insect reared on Chinese chive had the highest survival rate and reproductive value. The population projection revealed B. odoriphaga had explosive population growth in a relatively short time when reared on Chinese chive. These findings demonstrated that B. odoriphaga can successfully survive on artificial diet and five host plants, and our results showed the superiority of mass rearing B. odoriphaga on Chinese chives and the laboratory-prepared diet. These findings obtained under laboratory conditions also lay the basis for further studies of the population development of B. odoriphaga in the different host plants fields.

    ABSTRACT: One effective method for the management of soilborne pathogens is soil disinfestation. The basic idea is to treat the soil by drastic means, before planting, in order to eliminate the pathogens surviving there, thereby ensuring the health of the subsequent crop. There are two basic approaches to soil disinfestation: chemical, using fumigants, and physical, by heating the soil (mainly by steam). These approaches were developed in 1870, in the early days of plant pathology, and the chemical approach has dominated ever since.

    ABSTRACT: The solenopsis mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has emerged as an aggressive pest on a wide range of host plants in many countries. Mealybug demes were found on young tender leaves, twigs, inflorescence panicles and fruit peduncles of cashew Anacardium occidentale L. (Family: Anacardiaceae). Drying and curling of inflorescences, tender leaves and twigs were observed due to sucking of sap or saliva injection by nymphs and adults of mealybugs. The mealybugs were identified as Phenacoccus solenopsis Tinsley. The peak infestation of 20.73 mealybugs/ 5 cm twig was recorded in the months of April and May during 2012. The endoparasitoid Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae) was also recorded from mummies of P. solenopsis. This is the first report of P. solenopsis infestation on cashew, which may emerge as a sporadic pest of A. occidentale in India.

    ABSTRACT: Clematis manshurica Pupr. is a perennial herb in the Ranunculaceae family, which has been used as a valuable traditional Chinese medicine. Between 2012 and 2013, a powdery mildew causing significant damage to plants of C. manshurica occurred in the Medicinal Herb Garden in Shenyang Agricultural University, Liaoning province, China. The fungus from symptomatic tissues was identified as Erysiphe aquilegiae based on morphological characteristics and rDNA ITS sequence analysis. To the best of our knowledge, this is the first formal report of powdery mildew on C. manshurica caused by E. aquilegiae in China.

    ABSTRACT: A one-step RT-PCR was used to identify Tomato chlorosis virus (ToCV) (Crinivirus members) infections on some Tunisian cultures. Results provided evidence that the ToCV is the most prevalent virus on Tunisian tomato crops. Findings were validated with specific primers. Genetic analysis of ToCV isolates was explored based on sequence data of viral segments within the coat protein (CP), the heat shock protein (HSP70h) and the polymerase protein (RdRp). Synonymous (dS) and non-synonymous (dN) substitution rates and their ratio were analyzed. The patterns of mutations were shaped depending on the considered fragment from the three viral regions. Selective neutrality test was significantly negative, suggesting a recent expansion of ToCV isolates. Pairwise mismatch distribution gave a bimodal pattern and pointed to the clustering of ToCV isolates into two distinct geographical clades. Genetic haplotype network provided evidence of the existence of two distinct clusters. The star-like shaped pattern confirmed recent expansion of ToCV isolates.
