J. F. ROBINSON

Development, longevity, and reproduction of fall armyworms, Spodoptera frugiperda (J. E. Smith), from Louisiana (LA) and Puerto Rico (PR) were studied on an artificial diet and on rice foliage. PR larvae developed more slowly than LA larvae and produced lighter adult females. This difference did not extend to adult longevity or reproductive parameters, but the next generation of first instars was smaller. Developmental parameters were not influenced by diet. The results suggest the possibility of a genetic difference between the two populations, indicating some degree of reproductive isolation.

Effects of fall armyworm, Spodoptera frugiperda (J. E. Smith), feeding on rice, Oryza sativa L., were studied in the field during 1983 and 1984. Increased S. frugiperda infestation levels resulted in increased rice defoliation, reduced plant and panicle density, and reduced rice yields. Yield component studies indicated that lower yields on infested plots were the result of reduced plant stand and panicle density. Kernel weight and percent filled kernels were not affected. Yield reductions were linearly related to S. frugiperda larval density. The linear model [E(y) = bx1] accounted for a large proportion of the variance of yield reduction during both years.

A method for screening rice, Oryza sativa L., germ plasm for resistance to the fall armyworm, Spodoptera frugiperda (J. E. Smith), in a greenhouse was developed. In evaluation of >5,000 rice cultivars, moderate resistance to S. frugiperda larval defoliation was detected in plant introductions (PI) 160842, 346830, 346833, 346840, and 346853. Moderate levels of resistance were also detected in United States cultivars 'Honduras', 'Newrex', and 'Chinese', and in O. glaberrima Steud accessions 101800, 102554, and 369453. Differences in performance of PI 160842 in choice and no-choice experiments indicated that nonpreference resistance exists in this cultivar.

The rice water weevil (RWW), Lissorhoptrus oryzophilus Kuschel, was studied on the rice plant introduction PI 321264 (moderately RWW resistant) and the variety `Saturn' (RWW susceptible) in 1981 and 1982. PI 321264 sustained significantly (P < 0.01) lower larval populations and was significantly (P < 0.01) less preferred for feeding and oviposition than `Saturn.' Manly's instar duration determination technique revealed that the length of each larval instar was 1.20 (I), 2.56 (II), 7.14 (III), and 10.33 (IV) days, respectively. Taylor's power equation and Iwao's distribution function strongly indicated a clumped distribution pattern for immature RWW on each rice genotype for both years. The equation logeTn = loge(D20/a/b - 2) + (b - l/b - 2)logen indicated that 15 samples of `Saturn' and 19 samples of PI 3212564 are needed to estimate RWW larval populations with a relative variance of 10%.

A total of 106 cultivars of rice, Oryza sativa (L.), introduced, selected, or developed in the United States since the 1700s were evaluated for resistance to rice water weevil, Lissorhoptrus oryzophilus Kuschel, larval infestation, and adult foliage feeding in 1979 and 1980. The Phihppine cultivars Bontoc, Finindoc, and Carangiang; Nira, a pure line selection from an unknown Philippine variety: and Dawn, a hybrid with Philippine parents, all had significantly (P < 0.05) lower L. oryzophilus larval infestations than the most susceptible cultivars evaluated. Roots of Nira had 15% more small larvae and 12 and 3% fewer medium and large larvae, respectively, suggesting the presence of a growth-inhibiting factor(s). One-third of the 17 cultivars of Philippine origin had low L. oryzophilus larval populations (0 to 15 larvae per 9.2-cm soil-root core), whereas 37 other cultivars from six other centers of origin had either intermediate (16 to 30 larvae per core) or high (>30 larvae per core) larval populations.

The responses of Arkansas, Louisiana, and Mississippi populations of Lissorhoptrus oryzophilus Kuschel to topical application of carbofuran were studied during June, August, and October 1978 and March 1979. LD50s ranged from 4 to 12 ng/weevil, but were not significantly different (P ≤ 0.05) from previous baseline data; however, weevils from the northern most location (Stuttgart, AK) were ca. 30% more susceptible than weevils from 4 other locations. The mean weights of all weevils collected were significantly greater (P≤0.05) in June and August than in October or March. The 72 h LD50 for L. oryzophilus adults treated with 9 organophosphate, carbamate, and synthetic pyrethroid insecticides ranged from 8 ng/weevil (permethrin) to 389 ng/weevil (methyl parathion). None of the compounds tested were as toxic as carbofuran (7 ng/weevil). Permethrin and fenvalerate were significantly (P ≤ 0.05) more toxic to weevils at 16° than at 27°C.

... Data on FAW parasitoids and parasites fromTable 1 have been summarized as the number of species in each taxon reported from different geographical regions (Table 2).

... Other options such as chitin synthesis inhibitors (benzoylureas) and pyrethroids were first tested in the early 1980s. Fenvalerate was noted as having similar control as carbofuran, with the added bonus of having higher toxicities at low temperatures (Rahim et al. 1981). Trimufluron and diflubenzuron were also tested and found to have ovicidal activity and increased mortality in first-instar larvae (Smith et al. 1985, Smith and. ...

... In other studies, even though movement of A. glycines was shown to vary on resistant and susceptible soybean varieties in the greenhouse, spatial patterns of the insect in the field did not vary among varieties (da Silva Queiroz et al. 2018). Another study in rice was unable to detect differences in spatial patterns of the rice water weevil, Lissorhoptrus oryzophilus Kushel (Coleoptera: Curculionidae) on resistant and susceptible rice genotypes (Cave et al. 1984). More research is needed on how crop genotype may influence spatial patterns of insect pests. ...

... Levels of rice plant resistance to rice water weevil and fall armyworm have been documented in a wide range of commercial rice varieties under greenhouse or field conditions over the past few decades (Pantoja et al. 1986, Lye and Smith 1988, Vyavhare et al. 2016, Mohamad Saad et al. 2018). These studies have found significant variation in the levels of resistance of rice genotypes to the rice water weevil and/or fall armyworm, but none of these prior studies have investigated associations between resistance and EWs. ...

... Its larvae are caterpillars that act as leaf-chewing herbivores and these have an affinity for grass crops. Levels of S. frugiperda infestation are linked linearly to increases in rice defoliation, reductions in plant and panicle densities, and reductions in rice yields (Pantoja et al., 1986). Temperate japonica cultivars also tend to be more susceptible to FAW and other chewing insect herbivores than cultivars from other rice varietal groups (Heinrichs, 1986;Wang et al., 2022). ...

... Por isso, cultivares resistentes ao inseto, ao viabilizarem a redução de perdas de produção e da aplicação dos referidos inseticidas, são estratégicas para aumentar a rentabilidade dos arrozais e minimizar riscos de contaminação ambiental por resíduos químicos (Stout et al., 2001;Smith, 2005; Martins et al., 2017). Estudo pioneiro da resistência de arroz a O. oryzae no Brasil revelou menor infestação larval da cultivar Dawn (Him Him, 1980), que, posteriormente, foi relacionada como fonte de resistência ao gorgulho-aquático Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), nocivo à cultura nos Estados Unidos da América (Smith;Robinson, 1982;Heinrichs et al., 1985). A análise de cultivares comerciais e linhagens elites de programas de melhoramento genético de arroz, quanto à infestação de O. oryzae, evidenciou resistência dos tipos antixenose, antibiose e tolerância Terres, 1995), conforme descritos por Panda;Khush (1995), também detectados para L. oryzophilus (N'Guessan et al., 1994ab). ...

... The results of the present study are in close approximation with the findings of Ramalho et al. (2011) who opined that relative growth, consumption and metabolic rates as well as other nutritional indices were lower when larvae fed with Bt cotton leaves than those fed on non-Bt cotton. Similar kind of investigation was also carried on rice by Pantoja et al. (1987) on two strains of fall armyworm who reported that there were no significant differences in approximate digestibility or efficiency of conversion of ingested food. Further, it was said that ECD was identical for both FAW strains. ...
