“…Nutritional indices were calculated (Manuwoto andScriber 1982, Farrar et al 1989) with some modiÞca-tions: Relative Growth Rate (RGR) ϭ (A Ϫ B)/B ϫ day, where A ϭ weight of live insects (mg) on the third day/number of live insects on the third day and B ϭ original weight of insects (mg)/original number of insects. Relative consumption rate (RCR) ϭ D/(B ϫ day), where D ϭ biomass ingested (mg)/number of live insects on the third day.…”

Bioactivities of the Leaf Essential Oil of <I>Curcuma Longa</I> (Var. Ch-66) On Three Species of Stored-Product Beetles (Coleoptera)

et al. 2002

Essential oil extracted from the leaves of turmeric, Curcuma longa L., was investigated for contact and fumigant toxicity and its effect on progeny production in three stored-product beetles, Rhyzopertha dominica F. (lesser grain borer), Sitophilus oryzae L. (rice weevil), and Tribolium castaneum Herbst (red flour beetle). Oviposition-deterrent and ovicidal actions of C. longa leaf oil were also evaluated against T. castaneum. The oil was insecticidal in both contact and fumigant toxicity assays. The adults of R. dominica were highly susceptible to contact action of C. longa leaf oil, with LD50 value of 36.71 microg/mg weight of insect, whereas in the fumigant assay, adults of S. oryzae were highly susceptible with LC50 value of 11.36 mg/liter air. Further, in T. castaneum, the C. longa oil reduced oviposition and egg hatching by 72 and 80%, respectively at the concentration of 5.2 mg/cm2. At the concentration of 40.5 mg/g food, the oil totally suppressed progeny production of all the three test insects. Nutritional indices indicate >81% antifeedant action of the oil against R. dominica, S. oryzae and T castaneum at the highest concentration tested.

“…Food consumption and utilization by another generalist Spodoptera species, the southern armyworm ( S. eridania ) were compared among maize lines with different DIMBOA levels, which had been bred for resistance towards O. nubilalis (Manuwoto and Scriber 1982). Penultimate instar S. eridania grew less when feeding on high DIMBOA plants, while showing lower ECD and ECI.…”

Plant defense and herbivore counter-defense: benzoxazinoids and insect herbivores

et al. 2016

View full text Add to dashboard Cite

Benzoxazinoids are a class of indole-derived plant chemical defenses comprising compounds with a 2-hydroxy-2H-1,4-benzoxazin-3(4H)-one skeleton and their derivatives. These phytochemicals are widespread in grasses, including important cereal crops such as maize, wheat and rye, as well as a few dicot species, and display a wide range of antifeedant, insecticidal, antimicrobial, and allelopathic activities. Although their overall effects against insect herbivores are frequently reported, much less is known about how their modes of action specifically influence insect physiology. The present review summarizes the biological activities of benzoxazinoids on chewing, piercing-sucking, and root insect herbivores. We show how within-plant distribution modulates the exposure of different herbivore feeding guilds to these defenses, and how benzoxazinoids may act as toxins, feeding deterrents and digestibility-reducing compounds under different conditions. In addition, recent results on the metabolism of benzoxazinoids by insects and their consequences for plant-herbivore interactions are addressed, as well as directions for future research.

“…Glucosinolates induced gut-irritant effects on the migratory locust, Locusta migratoria (Cottee et al, 1988), but ECI and RGR values were not affected when the locust ingested the plant's secondary compound, sinigrin (Bernays, 1990). This could be due to allelochemicals in maize reducing performance values of Spodoptera eridania (Manuwoto and Scriber, 1982).…”

The effects of diet on quantitative nutritional indices were measured in fifth-instar female nymphs of the grasshopper, Euprepocnemis plorans. Analysis of the main and interactive effects of feeding on the host plants lupine (Lupinus termis), horsebean (Vicia faba) or clover (Trifolium alexandrinum) and some of the plants' allelochemicals indicated that nymph performance was adversely affected by the hydrogen cyanide (HCN) and quinolizidine in horsebean and lupine respectively. Assimilation of clover was higher than of lupine or horsebean. Relative growth rate (RGR) was significantly higher in grasshoppers fed on clover than in those fed on either lupine or horsebean. Relative consumption rate (RCR) was in the order lupine > clover > horsebean. The efficiency of the digested and ingested food conversion were significantly lower in grasshoppers fed on lupine or horsebean than those fed on clover. The duration of the fifth instar was in the order horsebean > lupine > clover. Grasshoppers fed on horsebean or lupine lost weight during the experiment, with a greater weight loss recorded in those fed on horsebean. Grasshoppers contained the highest concentration of haemolymph proteins when fed on clover. Short-term feeding on lupine and horsebean resulted in 10 and 20 % mortality respectively, and nymphs that died on a horsebean diet were malformed.
