“…In addition to NSKE, CLE also showed about 48.77% reduction in the mean number of H. armigera. This is in accordance with the findings of Barbozasilva et al [44]; they have reported that cis-dehydrocrotonin extracted from Croton cajucar bark inhibits the growth of Heliothis virescens. The percentage reduction of H. armigera in BLE treated plots may be due to the antifeedant and/or toxic effects.…”

“…According to Kubo et al [32] diterpenes from C. cajucara inhibit the growth of Heliothis virescens. The dichloromethane and ethyl acetate fraction of C. urucurana causes 65% mortality in the larvae of Anagsta kuehniella due to the action of phenolic compounds catechin and gallocatechin [33]. The adult mortality of Dystercus maurus was significantly higher in C. urucurana treated insects [34].…”

Aqueous extract of individual and mixed form of Azadirachta indica A. Juss seeds kernel and leaves of Milletia ferruginea, Hochst and Croton macrostachyus Hochst was tested against African bollworm, Helicoverpa armigera Hubner. Antifeedant activity of selected plant extract was tested at 1%, 2.5%, 5% and 10% concentration against 4 th instar larvae of H. armigera in the laboratory and 5% concentration was tested under field condition. All the tested plant extract showed 100% protection at 5% and 10% concentration. Among the various botanical treatment Neem Seed Kernel Extract (NSKE) and NSKE+BLE (Birbira Leaves Extract) was effective at 2.5% concentration with minimum pod damage. In the field observation among the botanicals, reduction of larval population in the treatment of NSKE, BLE and NSKE+BLE was statistically not significant (p>0.05; LSD). The lowest percentage pod damage (0.45%) was observed in Diazinon 60% EC treated plot followed by NSKE treated plot (3.90%) after second spray.The highest mean yield was obtained from NSKE treated plot (781 g) followed by Diazinon 60% EC treated plot (719.33 g), NSKE+BLE (656.67 g) and BLE treated plot (653.33 g). Five days after second treatment there was a significant difference in the mean number of ants between NSKE+BLE, control and other treatments. The highest mean number of spiders was observed in control plot (3.6) and lowest (0.3) was in plot treated with Diazinon 60% EC. The reduction of lady bird beetle population among the botanicals treated plots was statistically not significant (p>0.05; LSD). The mean number of wasp population was the highest in control plot (3.3) and there was no wasp observed in Diazinon 60% EC treated plot. In conclusion, even though Diazinon 60% EC was found to be effective by considering the interaction of beneficial in the field botanical preparations are much better particularly NSKE and also suitable to spray under rain fed condition to protect the crop by small farming communities.

“…Nutrients and secondary compounds of ingested foods do have significantly positive or negative effects on growth, survival, and potential fecundity of herbivorous insects via digestive physiology alteration (Mendiola-Olaya et al, 2000;Silva et al, 2009). Amount of consumed food and growth of lepidopteran larvae directly correlate with quality of nutrient input from host plants (Mendiola-Olaya et al, 2000;Silva et al, 2009).…”

“…Amount of consumed food and growth of lepidopteran larvae directly correlate with quality of nutrient input from host plants (Mendiola-Olaya et al, 2000;Silva et al, 2009). In the current study, it found considerable variability in both quality and quantity of different tomato cultivars because significant reductions were observed in values of larval weight and fecundity of C. chalcites.…”

Effects of six commercial tomato cultivars, Super Strain B, Super crystal, Hed rio grande, SUN 6108 f1, Rio grande UG and Cal.JN3 were determined on digestive physiology and life table parameters of Chrysodeixis chalcites (Esper). The highest values of consumed foods were determined in the larvae fed on Rio grande UG and Cal.JN3 while the lowest values were observed on SUN 6108 f1. Statistical difference was found in the pupal weight by the highest value on SUN 6108f1. The highest values of intrinsic rate of increase (r m ) and the net reproductive rate (R 0 ) were obtained on SUN 6108 f1 but the lowest values were obtained on Cal.JN3. Significant differences were also found in activities of digestive enzymes including specific proteases, α-amylase, glucosidases and TAG-lipase. Our findings showed that the highest and the lowest activities of specific proteases and TAG lipase were obtained on Rio grande UG and SUN 6108 f1, respectively. In addition, activities of the carbohydrases were the highest in the larvae fed on Cal.JN3. The demographical and physiological findings here revealed Cal.JN3 and Rio grande UG as the partially unsuitable cultivars for C. chalcites in comparison with other ones which may be recommended in integrated pest management. Keywords:Chrysodeixis chalcites, life table, digestive enzyme, tomato cultivar.Quality and quantity of host plants are described as presence of components affecting positively or negatively nutritional performance of herbivorous insects (Browne and Raubenheimer, 2003). These parameters depend on chemical compounds in host plants which are divided into four main groups including nitrogen-containing compounds, cyanogenic glycosides (glucosinolates), terpenoids and phenolics although some of them including alkaloids, phenolics, flavonoids and tannins are found occasionally in some families of plants (Schoonhoven et al., 1998). These chemicals, somehow defensive metabolites, are primarily toxic whereas others have anti-feedant and/or repellent properties leading to plant resistance against herbivorous insects. Host plant resistance occurs under three main mechanisms as antixenosis, antibiosis and tolerance by presence of secondary metabolites or morphological properties (Schoonhoven et al., 1998). Plants with antibiosis mechanisms may directly alleviate insect survival, size or weight, longevity and fecun-

“…About 500 μl of the larvae homogenate (0.8 μg of protein) were added to BAPNA and left to rest for 20 min at 37°C; after this, the reaction was stopped by adding 30% acetic acid (v/v). The trypsin activity was read in a microplate reader at 410 nm (ε, 10.0 mM -1 cm -1 ) in accordance with Silva et al (2009). The chymotrypsin activity was determined using N-succinyl-Ala-Ala-Pro-Phe-p Nitranilide (SAAP) as substrate.…”

This work describes the larvicidal activity of the ethanolic crude extract (EEB) as well as the hexanic (FH), chloroform (FCL), ethyl acetate (FAE) and remaining (FR) fractions obtained from Byrsonima intermedia leaves and bark against Aedes aegypti. Hexanic and remaining fractions from the leaves demonstrated larvicide activity against A. aegypti larvae on the 3rd stage, with LC 50 values of 250 and 125 μg/ml-1 , respectively, with less mortality as compared to the other fractions. Hexanic and remaining fraction from the leaves demonstrated larvicide acitivity against A. aegypti larvae on the 3rd stage, with LC 50 values of 250 and 125 μg/ml-1 , respectively, with less mortality as compared to the other fractions. Trypsin activities from gut of larvae treated with the extract or the fractions were significant (p < 0.05), and the major effects occurred with hexanic fraction (0.06 μmol min-1) and remaining fraction (0.09 μmol min-1) in the 1000 μg/ml-1 concentration, respectively. The same fractions inhibited chymotrypsin activity in 0.06 μmol/ml-1 (hexanic fraction) and 0.13 μmol/ml-1 (remaining fraction) at 1000 μg/ml-1. The inhibition was dose-dependent. The results show the inhibitory effects of the hexanic and remaining fractions from the leaves of B. intermedia on trypsin and chymotrypsin activity, which may be responsible for the deleterious effects on larvae mortality. The crude ethanolic extract and fractions of the bark does not inhibit the synthesis of trypsin compared to control. The results show the inhibitory effects of the hexanic and remaining fraction from the leaves of B. intermedia on trypsin and chymotrypsin activity, which may be responsible for the deleterious effects on larvae mortality.
