We summarize the economic importance, biology, and management of soft scales, focusing on pests of agricultural, horticultural, and silvicultural crops in outdoor production systems and urban landscapes. We also provide summaries on voltinism, crawler emergence timing, and predictive models for crawler emergence to assist in developing soft scale management programs. Phloem-feeding soft scale pests cause direct (e.g., injuries to plant tissues and removal of nutrients) and indirect damage (e.g., reduction in photosynthesis and aesthetic value by honeydew and sooty mold). Variations in life cycle, reproduction, fecundity, and behavior exist among congenerics due to host, environmental, climatic, and geographical variations. Sampling of soft scale pests involves sighting the insects or their damage, and assessing their abundance. Crawlers of most univoltine species emerge in the spring and the summer. Degree-day models and plant phenological indicators help determine the initiation of sampling and treatment against crawlers (the life stage most vulnerable to contact insecticides). The efficacy of cultural management tactics, such as fertilization, pruning, and irrigation, in reducing soft scale abundance is poorly documented. A large number of parasitoids and predators attack soft scale populations in the field; therefore, natural enemy conservation by using selective insecticides is important. Systemic insecticides provide greater flexibility in application method and timing, and have longer residual longevity than contact insecticides. Application timing of contact insecticides that coincides with crawler emergence is most effective in reducing soft scale abundance.

“…Temperature is the most influential weather parameter that greatly affects the population dynamics of insect pests (Arun, 2003) [63] . Baker et al (2012) [64] observed that the abundance of the insect pest and disease is correlated with weather factors (Khan et al 2020) [65] , showing the lowest population density in winter season when air temperature usually goes down. Seasonal population dynamics of any pest provide insight into the relationships of weather factors with insect pests and diseases.…”

The main aim of this review is to document the insect pests and diseases of jackfruit (Artocarpus heterophyllus L.) and their management in Bangladesh compared to other jackfruit growing countries. This article was based on mostly literature review. A. heterophyllus being the national fruit of Bangladesh, is widely consumed by most of the rural people. All parts of the fruit and tree are used as human food, animal feed and wood source for furniture. Jackfruit contains anti-bacterial, anti-diabetic, anti-oxidant, anti-inflammatory and anti-helminthic properties. The fruit is rich in carbohydrates, minerals, carboxylic acids, dietary fiber, vitamins and minerals. The seed is rich in manganese, magnesium, potassium, calcium iron and lectins and thus meets up nutritional requirements for the rural people. Despite the importance, a number of insect pests and diseases attack jackfruit plant and fruit. Shoot and fruit borer (Diaphania caesalis Walker) and trunk borer (Batocera rufomaculata De Geer) have been reported as major insect pests, while stem and fruit rot (Rhizopus artocarpi), bacterial dieback, pink disease (Pelliculana salmonicolor), leafspot (Phomopsis artocarpina), fruit bronzing (Pantoea stewartia Smith) and Gummosis (Phomopsis artocarpi) have been reported as major diseases. The pruning and training are an effective management technique for the insect pests and diseases. This technique provides well ventilation and reduces relative humidity at tree canopy level. Bordeaux paste is a common fungicide for the management of jackfruit borer pest and rhizopus rot, leaf spot, dieback and gummosis diseases. This paper has heighted the multifarious benefits of jackfruit plant and described the problems and solutions of jackfruit cultivation in agroforestry system of Bangladesh.

Seasonal abundances of the sucking insects, namely mealy bug, white fly and scale insects, and chewing insect viz., fruit fly was monitored during September, 2016 to June, 2017 in a guava Psidium guajava orchard. Sucking insect was monitored by weekly observation on the leaves and chewing insect was captured using methyl eugenol trap. The mealy bug, white fly and scale insects were abundant during 4th week of November to 4th week of January and they showed fluctuations in their population. The mealy bug, white fly and scale insects had peak abundance in the 1st week of January, 4th week of November and 1st week of December, respectively. The scale insect revealed significantly higher abundance compared to other sucking insects. Two species of fruit fly, namely Bactrocera tryoni and B. dorsalis were found in the guava orchard and B. tryoni showed significantly higher abundance compared to B. dorsalis both in winter and summer seasons. In winter, B. tryoni reached the peak abundance in the 2nd week of January and their peak abundance in summer occurred in the 1st week of May. The daily mean temperature and relative humidity influenced the abundance of the sucking and chewing insects. Temperature individually contributed 30.0, 59.6, 59.3% abundance and temperature with relative humidity had 34.8, 60.9 and 73.5% abundance on mealy bug, white fly and scale insect, respectively. The effect of temperature on the abundance of fruit fly in winter and summer were 42.6 and 50.3%, respectively and the combined effect of temperature with relative humidity were 68.7% in winter and 61.9% in summer.
