“…As a result, the food use efficiency and survival rates of immature stages decline, and the total larval developmental period increases. Afaq (2012) also reported that overall mortality was greatest at a larval density of 24 and least at a larval density of four.…”

“…Females oviposit singly or in clusters on stems, leaves, inflorescences, and axillary or terminal buds (Dhileepan et al 2000a(Dhileepan et al , 2000bDhileepan and McFadyen 2012). The eggs are yellowishorange, oblong, 1 mm in size, finely reticulated, and usually hatch within 4-5 days after oviposition Bali 1993a, 1993b;Sushilkumar 2005a;Afaq 2012). The newly emerged larvae eat inflorescences and new axillary buds (Dhileepan et al 2018).…”

“…Intraspecific interactions among Z. bicolorata have been shown to dramatically reduce the growth, development, and survival of the insect's developmental stages. Crowding due to increased larval density decreases area available for the larvae to move and increases competition among larvae for food (Omkar and Afaq 2009;Afaq 2012). As a result, the food use efficiency and survival rates of immature stages decline, and the total larval developmental period increases.…”

“…Photoperiod controls the circadian rhythm of an organism and is responsible for the time-activity allocation that characterises a species as diurnal, nocturnal, or crepuscular (Beck 1980). According to Afaq and Omkar (2016), various life history traits of Z. bicoloratahatching, moulting, eclosion, mating, oviposition, etc.are controlled by circadian rhythms. Although these rhythms are produced endogenously, they are entrained by the surrounding environment.…”

“…The studies revealed that twice-mated females and unmated males were preferred as mates for their superior reproductive performance and proven survivability. In addition, Afaq (2012) showed that females that had mated with previously mated males appear to be willing to mate again sooner than females that had mated with unmated males.…”

Parthenium hysterophorus Linnaeus (Asteraceae), commonly known as “congress grass,” is among the 10 worst weeds of India and is considered one of the world’s 100 most harmful invasive species. This species has been introduced accidentally into several countries, including India, and is a major agricultural and rangeland weed in more than 45 countries. It affects crop production, suppressing biodiversity, crop yields, the health of farm animals and human beings, and local and regional economies. Biological control has been found to be a cost-effective management strategy to control the weed, with the leaf beetle, Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae), considered an effective and safe biocontrol agent. Several studies have investigated the beetle’s biology, reproduction, and other life attributes. This review compiles the existing information about Z. bicolorata biology, growth, development, reproduction, food, and host specificity, and the effects of abiotic and biotic stressors on the insect’s life attributes. We anticipate that this review will helpful for improving strategies for this bioagent’s swift mass rearing and for developing classical biological control design for Parthenium weed.
