Results obtained revealed that the prey species had significant effect on the development and predation rate of H. convergens immatures. The shortest total larval developmental period (12.82 days) was observed for the beetle fed on A. craccivora, whereas the longest (16.32 days) was recorded for the beetle fed on H. pruni. H. convergens consumed significantly more individuals of H. pruni (278.34) during its larval period than A. craccivora (186.76), B. brassicae (227.87) and A. illinoisensis. (211.94). The lowest immature stages mortality rate was recorded when they were fed on A. craccivora (6.47%), followed by those fed on A. illinoisensis (8.05%), B. brassicae (9.65%) and H. pruni (13.6%). Meanwhile, adult females consumed significantly more individuals of H. pruni (4937.40) than B. brassicae, A. illinoisensis (3693.92, 3432.15) and A. craccivora (2953.5). Highest fecundity (564.00 eggs) was recorded when females of H. convergens were fed on A. craccivora. In addition, beetle adult females and males that fed on H. pruni had significantly longer life span than those fed on the other three aphid species. The investigation provides useful information for the utilization of the H. convergens predator in IPM programs to protect faba bean, cabbage, grapevine and stone fruit trees from aphids as well as other sap sucking pests.

Plant extracts were separately tested under laboratory conditions against the beetles using a topical spray. Beetles were sprayed with plant suspensions at different concentrations (1, 2 and 3 ml/L) for both Tondxier and Palazin. Mortality was recorded daily for 15 days while beetles were kept on wheat flour. Both Tondxier and Palazin had an impact on T. castaneum. Commercial Tondxier was more effective than Palazin at the same concentrations tested. Nevertheless, significant differences in the mortality rate at the end of the experiments between second, and 5 th instar larvae and adults treated with Palazin and Tondxier extracts were observed. Second and 5 th instar larvae were more susceptible, and adults were more resistant to Palazin and Tondxier treatments. This study showed that mortality rate increases with increased concentration and length of exposure times. Results obtained suggested that the two plant extracts of Palazin and Tondxier used in this study can be used as potent insect control agents.

Arab Journal of Plant Protection, 41(1): 1-7. https://doi.org/10.22268/AJPP-41.1.001007 Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a polyphagous insect pest causing major losses of corn crop in Pakistan. Biology and feeding potential of S. frugiperda was evaluated on three economically important crops including maize, Zea maize L. (Poaceae); sorghum, Sorghum bicolor L. (Poaceae); and cabbage, Brassica oleracea L. (Cruciferae) under laboratory conditions. The findings of this study showed that relative consumption rate (RCR) of S. frugiperda was 3.61 mg/mg/day, relative growth rate (RGR) was 0.78 mg/mg/day, the efficiency of conversion of ingested food (ECI) was 31.6%, and approximate digestibility (AD) was 56.46% feeding on maize leaves and was higher compared to other host plants. However, RCR (0.687 mg/mg/day), RGR (0.29 mg/mg/day), ECI (17.5%) and AD (33.96%) values were lower when larvae fed on cabbage leaves. Similarly, large larval instars completed their development faster when they fed on maize leaves. The larval mortality rate was also lower (13.3%) when they fed on maize leaves as compared to sorghum (20.0%) and cabbage (36.7%). Overall, it is concluded that the maize crop was the most suitable host plant for S. frugiperda as the growth and development of the insect was higher compared to other host plants in this study. But in the absence of a favored host i.e. maize, it can feed and develop on other hosts such as sorghum and cabbage. Information on the biology and feeding indices of pests could be very useful in developing integrated pest management tactics and improving crop production.

Therefore, it has received a lot of attention through the ages. Despite this importance, it is still facing many problems in all countries especially in Iraq. One of the obstacles of honeybee industry development is the aggressive behavior of this beneficial insect. This review examined the complex integration of external stimuli, reactions, and response to olfactory, visual, and mechanical signals. It was concluded that the strength of the colony, its queen health, her production of eggs, and the abundance of food sources, all have a role in determining the aggressiveness of bees. The physiological explanation of this behavior is the secretion of alarming pheromone, isopentyl acetate, which leads to an increase in the level of serotonin and dopamine in the brains of bee workers. Moreover, the location of the olfactory and visual receptors, and the number of sensory cells in the antennae, which varies according to honeybee races, resulted in a complex response of defensive reactions that include guarding, recruiting, alerting, attracting, culminating, biting, stinging, and pursuing.

All sub-lethal concentrations caused a significant decrease in oviposition period, total fecundity, longevity, and total life span of C. carnea compared to the control. Maximum and minimum mean lifespan of C. carnea individuals were observed in the untreated group and LC30 concentration of novaluron. Total fecundity varied from 153.47 offspring/individual in treatment with LC30 novaluron to 300.12 offspring/individual in the control treatment. The highest value for intrinsic and finite rate of increase (r, λ) was obtained by the concentration of lambda-cyhalothrin. The net reproduction rate (R0) reached its lowest level in novaluron treatment. As a result, the effects of sublethal concentrations of lufenuron, novaluron, and lambda-cyhalothrin on C. carnea were assessed and discussed to design improved integrated management programs.

The nematodes associated with citrus slow decline were isolated and phenotypically diagnosed based on microscopic examination of the infected stained roots, and juveniles in the soil based on the phenotypic characteristics of the citrus nematodes. Infestation rate in citrus orchards was assessed, and the severity of infestation was determined based on the number of females in 2 gm roots and the number of juveniles in 100 gm of the rhizospheric soil surrounding the roots. The causes of infection dissemination and the factors that contribute to the increase of infection in the severely affected orchards were investigated. The results of the field survey showed the presence of citrus nematodes infestation in all orchards and in all regions. The incidence and severity of citrus nematode infection differed between the different sites. It was found that the severity of infection was significantly higher with older trees compared to newly established orchards with young plants. The results of the questionnaire accompanying the field survey showed that most citrus orchards were not subject to nematode control practices.

Arab Journal of Plant Protection, 41(1): 18-27. https://doi.org/10.22268/AJPP-41.1.018027 Using chemical pesticides has several adverse effects on the environment and human health. Therefore, natural plant extract products may provide an alternative to chemical pesticides for the control of stored pests and reduce the impact caused by chemical pesticides. The use of aromatic essential oils in the management of insect pests has recently gained popularity due to their chemical composition and the presence of many important compounds for controlling harmful insects, such as stored grain pests. A series of laboratory studies were conducted to determine the lowest dosage of the insecticide Abamectin combined as (1:1) with Eucalyptus oil against the insect's adult, third, and fifth stage larvae khapra. In addition, the repellency or attraction of Eucalyptus oil has been examined. The findings indicated that various concentrations of Abamectin were used against the khapra beetle; the death rates of the concentrations (0.6 and 0.15 ml/L) were 91.67 and 78.33% compared to the control. The concentration 0.3 and 0.15 mg/L when mixed with Eucalyptus oil (1:1) gave 98.33 and 86.67% mortality, respectively, compared to the control, which was 0.00%. The result also indicated that mortality rates were highest by the concentration of 0.6 ml/L with a death rate of 85.55 and 80.00% of the third and fifth instar larvae, while the concentration of 0.15 ml/L gave death rates of 74.44 and 67.77%, respectively. the addition of Eucalyptus oil at a ratio of 1:1 to the insecticide concentrations 0.3 ml/L led to an increase in the mortality rates of the third and fifth instar larvae that reached 88.89 and 85.55%, respectively. Likewise, the death rates of using the insecticide concentration of 0.15 ml/L were 81.11 and 82.22%, respectively. The study also indicated the effect of Eucalyptus oil alone on the percentage of death of adults, the third and fifth instars of the Khapra beetle were 83.33, 48.61 and 65.55%, respectively, whereas the death rate for the control treatment was 1.67%. The study also confirmed that Eucalyptus oil had an 83.00% repellant effect on adults, whereas it had an 84.50% attraction effect on fifth-stage larvae. The study suggests using these essential oils as a potential safe alternative to insecticides.
